Ms. Moreno’s intenSati program helped bring positive psychology into the exercise world.Patricia Moreno, who injected a dose of spirituality into the world of fitness and created a popular exercise program called intenSati, which became a staple at some Equinox gyms and a presence on YouTube, died on Jan. 22 at her home in Los Angeles. She was 57.The cause was cervical cancer, her wife, Kellen Mori, said.Ms. Moreno began teaching workout classes more than two decades ago and founded intenSati in 2002, melding the word “intention” with the Sanskrit term “sati,” for mindfulness or awareness. Between bouts of kickboxing and aerobics, she would intersperse refrains like “I am worthy of my own love” or “Everything I need is within me,” adding liberal doses of mindfulness, journaling and other self-help practices.It was a melding of spirituality and exercise, something relatively new.Posted online, her workouts and spoken positive mantras — which she termed “affirmations” —  drew a sizable following, including 6,500 YouTube subscribers and 18,000 Instagram followers. The program includes more than 1,000 “intenSati Leaders,” who teach their own classes, and has brought in about $5 million in revenue, according to Lucy Osborne, who took over intenSati after Ms. Moreno’s death.Ms. Moreno’s method resonated with those seeking spiritual and emotional connections to wellness. “People cry in class all the time,” she told Cosmopolitan magazine in 2013. “Whenever I train new intenSati instructors I always tell them, ‘If people are crying, you’re doing your job right.’”One of those instructors, Natalia Mehlman Petrzela, is also a professor of history at the New School in Manhattan and is writing a book about fitness in America. “Today, there are many programs that marry the language of enlightenment with intense exercise,” she said in an email, “but Patricia, who came out of the aerobics world of the 1980s and who was a serious student of yoga and meditation, was very early to integrate the two.”What sets intenSati apart from other fitness programs, Professor Mehlman Petrzela added, is “its sense of playfulness and presence outside of the luxury, high-end fitness world.” In addition to Equinox clubs, primarily in New York and Los Angeles, intenSati instructors teach at community centers and have made workouts available at no cost on social media.Danielle Friedman, the author of “Let’s Get Physical: How Women Discovered Exercise and Reshaped the World” (2022), said in an email that Ms. Moreno’s program “helped to shift the language of fitness culture away from one of self-criticism, guilt and shame and toward one of celebration, joy and affirmation.”Patricia Esperanza Moreno was born on Aug. 14, 1964, in San Jose, Calif., to Jose and Edith (Salcido) Moreno. Her father was a lawyer, and her mother ran a restaurant. She had 10 siblings. After graduating from James Lick High School in San Jose, she took classes at San Jose State College.Overweight as a child, Ms. Moreno became interested in fitness as a way to manage her weight. She began teaching fitness classes in California in her teens. In the 1990s, she moved to New York City and found work teaching a kickboxing fitness class at a newly opened Equinox gym; she eventually became one of its highest-paid instructors.A 1995 article about fitness clubs in The New York Times described Ms. Moreno as one of Equinox’s most popular teachers in New York. She “shows up in a flannel shirt, black pants and a white muscle shirt,” the reporter, Jennifer Steinhauer, wrote. “Calling out a few steps here and there, she dances with almost no self-consciousness, as if all the people in her class were guests at a party in her living room and just happened to be wearing Lycra.”Ms. Moreno and Dr. Mori, a dentist, met in 2006, when Dr. Mori was taking an intenSati class in Manhattan. They married in 2008.In addition to Dr. Mori, she is survived by her daughters Olivia, Sophie and Stella Moreno-Mori and her siblings Edith Shipton, Denise Gossett, Darsie Marie Moreno, Marilyn Moreno, Norma Moreno-Grimnes, Elizabeth Ziegenhagen, Hector Moreno, Sylvia Rich and Jesse Moreno.After her diagnosis of stage-four cervical cancer, Ms. Moreno continued her intenSati practice and documented her experience on Instagram and other social media platforms, emphasizing the spiritual side of her work.“This diagnosis and all that’s come along with it,” she wrote on Instagram in September, “is revealing to me how important it is to focus on reconnecting to the broader part of me and not limiting my view of myself as a physical body.”

A Princeton sociologist and a single mother herself, she brought her own experience to her wide body of scholarly work.Sara McLanahan, a Princeton sociologist whose landmark studies of households led by one parent — much of which suggested poorer outcomes for children born to single mothers — laid the groundwork for research into the changing structure of the American family, died on Dec. 31 at her home in Manhattan. She was 81.The cause was lung cancer, her husband and research partner, Irwin Garfinkel, said.Dr. McLanahan’s research grew in part out of her personal experience as a single mother to three children, but it was also driven by her disappointment at the limited data available on single motherhood at the time. She was further prodded into action by an article she read.While completing a postdoctoral fellowship at the University of Wisconsin, Dr. McLanahan came across “The Underclass,” a 60,000-word article by Ken Auletta that appeared in three consecutive issues of The New Yorker in 1981. (It was later expanded into a book.) In it Mr. Auletta argued that the “weakened family structure of the poor’’ was a major reason for poverty in the country.She set out to design her own studies, hoping to contradict the thesis of “The Underclass.” But her research consistently found that single motherhood came with increased risk of income loss, conflict and poorer overall outcomes.“Her research showed that growing up in this single-parent family, even as you control for as much of the observables that you could possibly do with data, was damaging,” Dr. Garfinkel said in a phone interview. “And children did less well, and that was not very welcome news.”Despite that conclusion, Dr. McLanahan remained optimistic. She turned her sociological eye to public policy solutions. She pushed for mental health services for unmarried mothers as well as universal health care for children.Her best-known work was the Fragile Families and Child Wellbeing Study, which in 1988 took a longitudinal look at 5,000 children, primarily in households led by single mothers.The study, which she co-founded with Dr. Garfinkel and the Columbia University researcher Ron Mincy, identified major disparities in life outcomes — which she termed “Diverging Destinies” — between children with more involved mothers and those born to mothers with fewer resources and less time. She used four primary variables: mother’s age, mother’s employment, single motherhood and father’s involvement. The study over-sampled for single motherhood, using what researchers term “marital births” as a smaller control group.Older, more educated mothers who had jobs and who involved the children’s fathers led to better cognitive and social outcomes for their children, the study found; mothers who had children young and had more unstable relationships with the childrens’ fathers were correlated with worse outcomes. And, Dr. McLanahan argued, the gaps between the groups of children were widening.Dr. Garfinkel said the results of the Fragile Families study “provide no support for the culture of poverty thesis,” which posits that different values and behaviors among the poor trap them in self-perpetuating cycles of privation. Rather, he said, “circumstances and opportunities,” not value differences, have the greatest impact.Though her findings rankled some advocates for single mothers, Dr. McLanahan continued to publish books and papers on the topic.“We reject the argument that people should not talk about the negative consequences of single motherhood for fear of stigmatizing single mothers and their children,” Dr. McLanahan and the researcher Gary Sandefur wrote in their 1994 book, “Growing Up With a Single Parent: What Hurts, What Helps.” “While we appreciate the compassion that lies behind this position, we disagree with the bottom line. Indeed, we believe that not talking about these problems does more harm than good.”Sara Frances Smith was born on Dec. 27, 1940, in Tyler, Texas. Her father, Norman Smith, was a general manager for a local oil company. Her mother, Iredell (Brown) Smith, was a homemaker.She attended Robert E. Lee High School in Tyler, now known as Tyler Legacy High School. A gifted pianist, she studied at the Aspen Music Festival in Colorado for a summer. She attended Bennett Junior College in Irvington, N.Y., and went on to Smith College. After a year at Smith, she dropped out in 1962 and married Ellery McLanahan. They had three children, Sara, Ellery and Anna Bell, all of whom survive her. The family moved to Houston, and the couple divorced in 1972.Dr. McLanahan returned to school and graduated from the University of Houston with a bachelor’s degree in sociology in 1974. She received her masters and doctoral degrees in sociology from the University of Texas at Austin.She began her postdoctoral fellowship at the University of Wisconsin in 1979. It was there that she met Dr. Garfinkel and focused her research on single motherhood. (She had avoided the topic in her doctoral thesis at the University of Texas because, she said, it felt too close to home.) She and Dr. Garfinkel married in 1982.After completing the fellowship, Dr. McLanahan remained in Wisconsin as an assistant professor in sociology and became a full professor in 1989. She began her tenure at Princeton in 1990, and Dr. Garfinkel moved on to Columbia University. At Princeton, she was a founder of the Bendheim-Thoman Center for Research on Child Wellbeing.In addition to her husband and children, she is survived by her stepdaughters, Leah Matthew and Lynn Garfinkel, and five grandchildren.The Fragile Families data set has been used in nearly 1,000 published papers, according to a remembrance by the National Council on Family Relations, of which Dr. McLanahan was a member.

A playwright and actor, he saw his life as performance art. He was best known for his play “Storm Reading.”At each performance of his play “Storm Reading,” the writer and actor Neil Marcus offered his audience a reminder: “Disability is not a brave struggle or courage in the face of adversity. Disability is an art. It’s an ingenious way to live.”Mr. Marcus, who had dystonia, a neurological disorder that causes involuntary muscle contractions and affects speech, starred in the play, which comically illuminated how he passed through the world in a typical week, through vignettes of him conversing with grocery shoppers, doctors and passers-by.In 1988, when the show had its premiere at the Lobero Theater in Santa Barbara, Calif., people more often than not looked away from those with disabilities. “We’ve always been taught as kids we don’t point, don’t laugh, just basically ignore them,” Rod Lathim, the director of “Storm Reading,” said in an interview.In contrast, “Storm Reading” encouraged audiences to laugh with Mr. Marcus about his experiences.“Neil invited and welcomed, and in some cases demanded that people look,” Mr. Lathim said. “And so he brought them into his reality, which was not a reality of disability; it was a reality of his definition of life.”The success and longevity of the play, which toured throughout the country until 1996, turned Mr. Marcus into a pioneer of the disability culture movement. He called his work a reclamation of personhood in a world determined to deny people with disabilities their autonomy.Mr. Marcus died on Nov. 17 at his home in Berkeley, Calif. He was 67.His sister Kendra Marcus said the cause was dystonia,In 1987, Mr. Marcus and his brother Roger contacted Mr. Lathim, the director of Access Theater, a Santa Barbara company that regularly mounted plays featuring disabled artists. Neil Marcus sent over samples of his writing and asked Mr. Lathim if the theater would be interested in adapting them.Their conversation led to the genesis of “Storm Reading.” Mr. Marcus, his brother and Mr. Lathim worked together to draft the play, whose cast of three originally also included Roger as “The Voice,” who portrayed Neil’s thoughts during his interactions (the role was later played by Matthew Ingersoll), as well as a sign language interpreter.The show was physically taxing for Mr. Marcus. But it also invigorated him.“There’s no drug, there’s no treatment, that is, in my opinion, as powerful as the interaction between a live audience and an artist on the stage,” Mr. Lathim said. “And watching Neil transform from that was astounding.”Scenes from “Storm Reading” were filmed for NBC as part of a 1989 television special about disability, “From the Heart,” hosted by the actor Michael Douglas. The cast reunited in 2018 for a performance at the John F. Kennedy Center for the Performing Arts in Washington.Neil Marcus was born on Jan. 3, 1954, in Scarsdale, N.Y., the youngest of five children of Wil Marcus, who worked in public relations, and Lydia (Perera) Marcus, an actor. When Neil was 6, the family moved to Ojai, Calif.Neil was 8 when he learned he had dystonia, and he attempted suicide at 14 after a taxing series of surgeries, he said in a 2006 oral history interview for the Bancroft Library at the University of California, Berkeley.But counseling gave him confidence. He attended Ojai Valley School, where he was often spotted zooming around in a golf cart. After graduating from high school as valedictorian in 1971, he traveled to Laos; when he returned, he hitchhiked around the West Coast and eventually took classes at Fairhaven College, part of Western Washington University, and elsewhere. He moved to Berkeley in 1980 and became active in the disability activist community there.He explored art through various partnerships. With professional dancers, he participated in “contact improvisation” performances, which eschewed formal choreography and instead followed the seemingly frenetic movements of Mr. Marcus’s dystonia.He also wrote widely. He worked with the University of Michigan professor and activist Petra Kuppers on the Olimpias Performance Research Project, an artist collective that spotlights performers with disabilities in performances and documentaries. Their conversations on disability as art were published in a 2009 essay, “Research in Drama Education: The Journal of Applied Theatre and Performance.” The two also wrote a book, “Cripple Poetics: A Love Story” (2008), which features poetry and photography highlighting the physicality and sensuality of disability.The Neil Marcus Papers, including his essays, poems and correspondence, are held at the Bancroft Library.In addition to his sister Kendra, Mr. Marcus is survived by another sister, Wendy Marcus, and his brothers, Roger and Russell.In 2014 the Smithsonian National Museum of American History commissioned Mr. Marcus to write a poem dedicating its online exhibition “EveryBody: An Artifact History of Disability in America.”His poem began: “If there was a country called disabled, I would be from there./I live disabled culture, eat disabled food, make disabled love,/cry disabled tears, climb disabled mountains and tell disabled stories.”

She studied the impact of AIDS on women and explored the effects of famine and poverty on health with an “unwavering commitment to social justice.”Dr. Zena Stein, a South African-born epidemiologist whose influential work encompassed the effects of famine on children, the health of entire communities afflicted by poverty and the impact of the AIDS crisis on women in Africa, died on Nov. 7 at her home in Coatesville, Pa. She was 99.Her daughter Ida Susser confirmed her death.Dr. Stein came of age in South Africa during World War II and started her career in the early years of institutionalized apartheid. Those backdrops shaped her approach to epidemiology: She aimed to identify the social, economic and political conditions that can affect the health of a population as well as individuals, an approach known as social medicine or community-based medicine.Dr. Stein’s research focused closely on women’s health at a time when the bulk of scientific study spotlighted men. She was also well known for her research on child development and on mental illness.She and her husband, Dr. Mervyn Susser, worked as a team and conducted hundreds of studies, many of which shaped the field of epidemiology and community health care. Dr. Stein is listed as the author or co-author of 270 academic articles and several books, including “Eras in Epidemiology: The Evolution of Ideas” (2009), which she wrote with Dr. Susser.Early in their careers, the couple ran a clinic in the South African township of Alexandra, near Johannesburg, with another husband-and-wife medical team. In one of their first articles, written with collaborators and appearing in the scientific journal The Lancet, they demonstrated that melding medical care and social support made people healthier. The clinic taught patients and family members, for example, how to care for illnesses at home and pregnant women how to improve nutrition. Varieties of the treatment plans Dr. Stein helped develop are still in use today.In a tribute to her and Dr. Susser in the journal Pediatric and Perinatal Epidemiology, the researchers Richard Neugebauer and Nigel Paneth wrote that the Lancet article “presages enduring themes” in the couple’s work.“On the scientific level, it reflects their commitment to an analysis of human health centered both on the immediate environment and larger society,” they wrote, adding, “On a deeper level of conscience and morality, it signals their unwavering commitment to social justice.”Dr. Stein often spoke of her most treasured accomplishment: a seminal study in 1972 on a nine-month stretch of famine in the Netherlands during World War II. The study was based on government data assembled and examined by Dr. Stein and Dr. Susser. In a finding that countered the accepted wisdom, they showed that babies born during a famine were no more likely to experience cognitive deficiencies than babies raised with plentiful food. (Later research, however, showed possible links between prenatal famine exposure and congenital nervous system problems.)The Dutch famine data had implications for research on prenatal nutrition. Further studies by other scientists using the data pointed to folate, or the various forms of vitamin B9, as a key nutrient during pregnancy, and led the U.S. government to recommend daily folic acid supplements during gestation.The large data set is still in use today, including by Dr. Stein’s son, Dr. Ezra Susser, a former chairman of Columbia University’s epidemiology department.Dr. Stein later turned her attention to the effects of the H.I.V./AIDS crisis on women, who made up a minority of patients and were often overlooked. She was a proponent of a female condom for AIDS prevention, particularly in South Africa, where treatment options were more limited. Securing institutional funding for her work, her daughter Ms. Susser said, presented a perennial challenge: Medical authorities did not place great value on AIDS research focused on women. But Dr. Stein was not cowed and found ways to publish nonetheless.As she told The New York Times in 1990, “If we’re serious about preventing H.I.V. infection in women, then we’re going to have to empower women.”Dr. Stein was a proponent of the female condom as a way to protect women from H.I.V. infection. Columbia University has materials on the subject from her papers.Columbia University LibrariesZena Athene Stein was born on July 7, 1922, in Durban, South Africa, to a family of Lithuanian Jewish immigrants. Her mother, Lily (Rolnick) Stein, was a homemaker. Her father, Philip Stein, was a mathematics professor at Natal Technical College, which became the Durban University of Technology.She attended the University of Cape Town for her bachelor’s and master’s degrees in history, and earned her medical degree in 1950 from the University of Witwatersrand. Dr. Susser also studied medicine there, and the two married in 1949. While in medical school, they organized a protest over the treatment of Black students, who were barred from observing autopsies of white cadavers.The couple, part of a leftist social set in Johannesburg, started their work at the clinic in Alexandra Township in 1952. They worked there for three years, until, in 1955, the clinic’s board threatened to fire Dr. Susser if he went ahead with a scheduled appearance on a panel sponsored by the anti-apartheid African National Congress. He and Dr. Stein, staunch supporters of the A.N.C., resigned in protest.The couple had helped write guidelines for health care in South Africa’s Freedom Charter, the 1955 statement of principles by the A.N.C. and its allied parties.Dr. Stein and Dr. Susser, along with their three children, emigrated to Britain in 1958. They initially lived in boardinghouses and worried about money; Dr. Stein worked nights in a mental hospital. After a year, Dr. Susser found work at the University of Manchester, and Dr. Stein followed suit; she was a researcher there from 1959 to 1965.The family went to the United States in 1965, and Dr. Susser shortly received a job offer from Columbia University. Dr. Stein began teaching there as well, first as an associate professor of epidemiology, then earning a full professorship and assuming administrative positions in what is now the Mailman School of Public Health. Her work included research on developmental disorders in children.She and Dr. Susser were founding members of Columbia’s Gertrude H. Sergievsky Center, which originally studied disorders of the nervous system.In 1987, she founded the H.I.V. Center for Clinical and Behavioral Studies at the New York State Psychiatric Institute and Columbia University. The center embarked on the first major effort to draw attention to women living with AIDS. It is now one of the largest centers of its kind in the world, employing about 100 investigators and staff members in the study H.I.V. using different disciplines, including psychology, psychiatry, public health, anthropology, sociology and social work.Dr. Stein retained her South African roots, corresponding with Nelson Mandela, returning to her home country for conferences and speaking out for racial equity in the post-apartheid era.After retiring from full-time work in 2003, she continued to write articles with her husband, her daughter and other researchers. Dr. Susser died in 2014. In addition to their daughter and son, Dr. Stein is survived by another daughter, Ruth King; her brother, Wilfred Stein; eight grandchildren; and six great-grandchildren.In a remembrance on the Sergievsky Center’s website, a former student of Dr. Stein’s, the Columbia professor Dr. Louise Kuhn, wrote of her teacher’s relentless pursuit of knowledge.“She always wanted me to go further and deeper into understanding issues,” Dr. Kuhn wrote. “Is that all you can conclude?” she quoted Dr. Stein as saying. “Where does that take us? Can’t you do more?”

He wrote prolifically about grief, counseled the bereaved after 9/11 and the Oklahoma City bombing and paid particular attention to children. “Grief is the price we pay for love,” he’d say.Rabbi Earl A. Grollman, a prolific writer on grief who became widely known for ministering to those mourning the death of loved ones in the 9/11 attacks, the 1995 Oklahoma City bombing and other times of loss, died on Oct. 15 at his home in Belmont, Mass. He was 96.His daughter, Sharon Grollman, said that the cause was congestive heart failure.Rabbi Grollman was known nationally as an expert in the field of grief counseling, appearing on “Mister Rogers’s Neighborhood,” “The Oprah Winfrey Show” and other television programs. He ministered to people of all faiths, encouraging frank conversations about a topic that has often been taboo.He wrote more than two dozen books about death and grieving, including “Living When a Loved One Has Died” (1977), “Straight Talk About Death for Teenagers: How to Cope With Losing Someone You Love” (1993) and “Your Aging Parents: Reflections for Caregivers” (1997).His work took him to all corners of the country. After a far-right militant bombed the Alfred P. Murrah Federal Building in downtown Oklahoma City in 1955, killing 168 people, Rabbi Grollman flew in from Boston and made several presentations on dealing with grief. He spoke at the National Cowboy Hall of Fame in that city and met with survivors, family members and emergency medical workers.“One touch of sorrow makes the whole world kin,” he told The Daily Oklahoman in 1997, when he returned to the state to speak to emergency medical workers and others affected by the attack.Rabbi Grollman, who led the Beth El Temple Center in Belmont, Mass., for 36 years before retiring in 1987, was in Vancouver, British Columbia, attending a conference on bereavement on Sept. 11, 2001, when planes hijacked by Islamist militants crashed into the twin towers of the World Trade Center and the Pentagon. He said a member of his former congregation was a passenger aboard the fourth jetliner hijacked by the terrorists, United Airlines Flight 93, which was forced down into a field in Shanksville, Pa.“I’m telling people that the most important part for all of us at the moment is to feel free to feel all the reactions and feelings that we are experiencing,” Rabbi Grollman was quoted as saying in The Vancouver Sun.Indeed, he was a proponent of talking openly about dying and grief, something that came with difficulty for many people, he said. “Death has come out of the closet,” he told The New York Times in 1994.“For so many years people thought that if they didn’t talk about it, death would go away,” he continued. “It was the immorality of mortality. But for the first time, people are willing to acknowledge that living is the leading cause of death, and they want to talk about it.” He counseled mourners with his often-used adage “Grief is the price we pay for love.”His appearance on “Mister Rogers’ Neighborhood,” in 1981, was focused on the effect of divorce on children, and his message to them was that their negative feelings about their parents’ separation were OK, that they were natural.Jonathan Kraus, the current rabbi at the Belmont synagogue, outside Boston, said Rabbi Grollman’s work on children’s grief was an important part of his legacy. Rabbi Grollman, he said, understood that grief could be complicated for children but could translate those issues into simple language.“He had a capacity to make those ideas accessible without watering them down,” Rabbi Kraus said.Earl Alan Grollman was born on July 3, 1925, in Baltimore to Gerson and Dorah (Steinbach) Grollman. His mother taught Hebrew school; his father sold books and postcards at the city’s port.Earl became curious about grief at a young age. He recalled in an interview with Highmark Caring Place, an organization that helps young people deal with grief, that he had not been allowed to attend his grandmother’s funeral as a 14-year-old. The prevailing sentiment at the time was that children had no business experiencing death.He attended Hebrew Union College in Cincinnati and was ordained in 1950. He became an assistant rabbi at Temple Israel in Boston and then the rabbi of Beth El Temple Center in Belmont in 1951.At seminary, he said, he was not taught how to deal with death in a congregation, and this lack of communication about dying rankled him. After the death of a close friend, he wanted to counsel the bereaved family. But there were scant resources available that discussed death and grief in detail, he said.He published his first book on the topic, “Talking about Death: A Dialogue Between Parent and Child,” in 1970.Rabbi Grollman married Netta Levinson in 1949. Along with his daughter, his wife survives him, as do their sons, David and Jonathan; six grandchildren; and five great-grandchildren. His brother, Jerome, who died in 2008, was also a rabbi and led the United Hebrew Congregation in St. Louis.After Rabbi Grollman retired from Beth El to focus on writing and counseling, he returned there occasionally to recite the Yizkor, a memorial prayer for the dead, and regularly addressed the congregation into his 90s.“Obsessing about death can lead to paralysis, while ignoring it can squander opportunity,” he told The Times in 1994. “The important thing about death is the importance of life. Do what you have to do now. Live today meaningfully.”

She documented her last months with ovarian cancer on Twitter while raising funds to support students from backgrounds that are underrepresented in the sciences.Nadia Chaudhri, a neuroscientist with terminal ovarian cancer who used her final months to raise money for graduate students of diverse backgrounds and to educate the public about her disease through a widely followed social media chronicle, died on Oct. 5 at a hospital in Montreal. She was 43.Her husband, Moni Orife, confirmed her death.Dr. Chaudhri, a professor at Concordia University in Montreal, was in palliative care at Royal Victoria Hospital when she wrote on Twitter in August that she would be embarking on a walk-a-thon: pacing her hospital floor each day in a fund-raising appeal for minority, female, L.G.B.T.Q. and other students from underrepresented backgrounds who are pursuing scientific research at the university. Her own research centered on the neural basis of drug and alcohol addiction.Her campaign raised funds for the Nadia Chaudhri Wingspan Award, which was established in her honor and announced by Concordia in May. She had previously raised money with a GoFundMe campaign to sponsor students from diverse backgrounds to attend the annual conference of the nonprofit Research Society on Alcoholism.In the announcement of the award, Dr. Chaudhri recalled the discrimination she had experienced as a Pakistani woman in graduate school. “When I gave talks or presentations, people often commented on my accent instead of my science,” she said.Through her walk-a-thon and her large and active Twitter following, the fund surpassed $635,000 in mid-October. Paul Chesser, the university’s vice president for fund-raising, said small donors had led the way: nearly 9,000 from 60 countries, forming a rare grass roots effort in institutional fund-raising.“Nadia’s legacy is forever entrenched in many, many ways here on campus,” Mr. Chesser said.Dr. Chaudhri in 2014. She learned she had ovarian cancer in May 2020. “Do not dismiss your pain or malaise,” she wrote to her Twitter followers. “Find the expert doctors.”Moni OrifeHer Twitter feed drew more than 150,000 followers and was the backbone of her money-raising efforts. Many of her followers said they were inspired by her frankness about her illness and cited her bravery.“I’ve been so moved by your story, Nadia, and your kindness and spirit are just something I don’t think I’ve ever seen in such abundance before,” one Twitter user wrote. “I will carry you in my heart for as long as I live.”Dr. Chaudhri, in turn, connected closely with her Twitter following. Addressing donors, she wrote, “You are making my final days incredibly special & meaningful.”In May she wrote of how she was preparing to tell her 6-year-old son about her terminal diagnosis. “Today is the day I tell my son that I’m dying from cancer,” she said. “Let me howl with grief now so that I can comfort him.”Dr. Chaudhri produced creative work while in the hospital. She sent some donors copies of a short story she wrote about growing up in Karachi, Pakistan. She painted, posting vibrant artwork depicting flowers and nature scenes, some inspired by pictures her followers had sent her and some featuring her husband and son.She also used her Twitter platform to call for more research into ovarian cancer. “The bottom line is that ovarian cancer research is underfunded,” she wrote in September. “We also need more awareness of symptoms because early detection improves prognosis dramatically.”Dr. Chaudhri urged women to pay attention to their health. “Do not dismiss your pain or malaise,” she wrote in one thread recounting her diagnosis. “Find the expert doctors.”She was found to have ovarian cancer in May 2020. The cancer resisted treatment, she said, and she was admitted to palliative care in August this year.Nadia Chaudhri was born in Karachi on Jan. 25, 1978. Her mother, Susan (Metcalf) Chaudhri, was an occupational therapist. Her father, Abdul Shakoor Chaudhri, was an orthopedic surgeon.Nadia attended Karachi Grammar School in Pakistan. She went to the United States for college, earning a Bachelor of Science degree in the biological foundations of behavior from Franklin & Marshall College in Pennsylvania in 1999. She was the first woman to win the college’s Williamson Medal for academic and extracurricular achievement.She attended the University of Pittsburgh and received a Ph.D. in neuroscience in 2005, writing her thesis on the science of cigarette addiction. She had a postdoctoral fellowship from 2005 to 2009 at the Ernest Gallo Clinic and Research Center at the University of California, San Francisco.She married Mr. Orife in 2009. Their son, Reza Orife, was born in 2015. In addition to her husband and son, she is survived by her mother and her sister, Amina.Dr. Chaudhri joined the Concordia University faculty in 2010 as an assistant professor in the department of psychology and was placed at the head of her own lab. She earned tenure as an associate professor in 2014. Less than a month before she died, Concordia promoted her to full professor.
