The overall goal of the Research Education Component (REC) of the Boston OAIC is to train future independent research scientists who have the knowledge and the skill to translate fundamental mechanisms of disease and disability into novel interventions that can improve the health, physical function, and well-being of people as they age. The REC will achieve this by selecting the most promising early career scientists from clinical and basic science disciplines, and providing them with both collective and individual educational activities, research experiences, mentoring, and career guidance that will enable them to acquire future career development or research awards and ultimately become leaders in translational research devoted to the discovery of function promoting therapies (FPTs).

Dr. Lipsitz was one of the first geriatricians to be trained in the Harvard Geriatric Fellowship Program. He subsequently became a National Institute on Aging Academic (K23) Awardee, with Hebrew SeniorLife (formerly the Hebrew Rehabilitation Center for Aged) as his primary clinical and research site. As a fellow, he began a systematic series of epidemiologic and physiologic studies evaluating syncope and abnormal blood pressure regulation, discovered postprandial hypotension in the elderly, and subsequently acquired funding for his studies through an NIA-funded Program Project, which he directed for 20 years. In this capacity he provided on-site management and established strong working relationships with project directors from multiple Harvard-affiliated institutions. This program project supported the prospective, observational MOBILIZE Boston Study, which has elucidated numerous novel risk factors for falls over the past 10 years. Dr. Lipsitz’s research has been quite productive, resulting in 250 original articles in peer-reviewed journals, many of which involve clinical trials and translational research.

During his career, Dr. Lipsitz has received continuous NIA funding for his research, directed an Older Americans Independence Center, led a T32 training program and the Hartford Center of Excellence in Geriatric Medicine at Harvard Medical School (HMS), and acquired two D.W. Reynolds Grants for geriatric education at HMS. He has mentored 34 successful postdoctoral trainees, including 2 Beeson Scholars and 4 T32 trainees, and received the prestigious “William Silen Lifetime Achievement” award for mentoring. His research into various function promoting therapies, access to Harvard-wide resources, academic leadership experience, skills in mentoring, and familiarity with NIA Center Grants and Boston’s academic geriatric community all make him ideally suited to lead the Boston OAIC and its Research Education Component.
