Researchers from LSU’s Pennington Biomedical Research Center will be among the experts sharing advances in obesity science and treatment at ObesityWeek 2026 , the annual meeting of The Obesity Society, Nov. 14-17 in National Harbor, Maryland.
Pennington Biomedical will have a strong presence throughout the conference, with researchers presenting scientific findings, participating in expert panels and symposia, and contributing to educational and early-career programming. Dr. Jacqueline Stephens, a longtime Pennington Biomedical researcher, is serving as president of The Obesity Society, placing a Pennington Biomedical scientist at the helm of the organization behind one of the world’s leading gatherings devoted to obesity science and care.
“Pennington Biomedical’s participation in ObesityWeek reflects the extraordinary breadth of expertise across our research community, from basic science and precision medicine to clinical care and long-term treatment outcomes,” said Dr. Jennifer Rood, Interim Senior Vice Chancellor and Executive Director. “We are especially proud to support our own Dr. Jackie Stephens serving as president of The Obesity Society while so many of her Pennington Biomedical colleagues share discoveries that are helping advance the understanding and treatment of obesity.”
ObesityWeek is the annual scientific meeting of The Obesity Society and brings together scientists, clinicians and other health professionals working across the spectrum of obesity research, treatment and prevention.
“Obesity is a complex disease, and it’s encouraging to see that understanding finally spreading beyond the expert community. That momentum shows here: this is the largest ObesityWeek in TOS history, with more than 4,500 attendees from a wide range of fields, and our membership has grown 38% in the past year alone,” said Dr. Stephens, Claude B. Pennington Jr. Endowed Chair in Biomedical Research and TOS President.
Among the highlights of Pennington Biomedical’s participation:
Pennington Biomedical researchers will also help lead and facilitate programming throughout the conference. Dr. Catherine Champagne will moderate a discussion on food noise and serve as a session chair; Dr. Frank Greenway will lead a discussion on potential new obesity treatments; Dr. Katherine Spring will moderate a discussion on ultra-processed foods, brain development and chronic disease risk; Dr. Albaugh will moderate a panel discussion on collaborative obesity treatment; and Drs. John Apolzan and Timothy Allerton will serve as session chairs. Dr. Hanim Ecem Diktas will co-chair the Early Career Lightning Talks and the “Beyond Academia: Roadmap to What Comes Next” workshop, while Dr. Ryan will participate in the workshop’s panel discussion. Dr. Stephens will also participate in the conference’s presentation of awards.
Additional Pennington Biomedical researchers will share their work through posters and oral presentations during ObesityWeek, including Drs. Wentao Cao, Yun Shen, Sujoy Ghosh, Samantha Kennedy, Sri Lakshmi Sravani Devarakonda, Steven Heymsfield, Catherine Prater, Katherine Spring, Gang Hu, Yeongho Hwang, Eric Ravussin, Christian Rodriguez and adjunct professor Leanne Redman; and doctoral candidates Dachuan Zhang, Lindsey Yoo, Elizabeth Heintz and David Mendoza.
