John A. Batsis

John A. Batsis, MD is an Adjunct Associate Professor in the Department of Biomedical Data Science at the Geisel School of Medicine, Dartmouth College. He maintains dual affiliations with the Center for Aging and The Dartmouth Institute for Health Policy and Clinical Practice, focusing on geriatric syndromes and obesity management in aging populations.

His educational background includes:

• MD from University of Dublin, Trinity College (2002)
• Internship at St. James' Hospital (2002-2003)
• Internal Medicine Residency at Mayo Clinic College of Medicine (2003-2006)
• Geriatric Medicine Fellowship at Mayo Clinic College of Medicine (2006-2008)
• Certificate of Clinical Research from Mayo Clinic CTSA (2007-2008)

Dr. Batsis's research centers on the intersection of aging, obesity, and functional decline, with specific expertise in sarcopenia, frailty trajectories, and social determinants of health. His work integrates clinical geriatrics with data science methodologies to address physical function impairment in older adults through multimodal interventions and epidemiological analysis.

Recent publications (2024-2025) demonstrate consistent focus on obesity-aging interactions, featuring studies on voice-assisted cognitive impairment detection, sarcopenic obesity therapeutics, urbanization-frailty relationships, and obesity-related transitions to assisted living. Key methodological approaches include cross-sectional analyses of diverse populations (U.S., China, Qatar) and clinical trials targeting knee osteoarthritis-obesity comorbidity.

He currently holds NIH funding through grants K23-AG051681 and R01-AG067416, supporting investigations into behavioral interventions for functional decline and obesity-aging pathophysiology. Collaborative work spans multiple institutions with emphasis on translational applications for geriatric care.

Through the Center for Aging and The Dartmouth Institute, Dr. Batsis contributes to interdisciplinary teams developing evidence-based approaches for aging populations, with particular attention to rural-urban health disparities and implementation science in geriatric practice.
