Dr. Jeanne Nichols is Professor Emeritus in the School of Exercise and Nutritional Sciences at San Diego State University and currently Scientific Director of the Exercise and Physical Activity Resource Center (EPARC) in the Department of Family Medicine and Public Health at the University of California, San Diego. Dr. Nichols is an exercise physiologist specializing in musculoskeletal health across the lifespan, in populations ranging from young athletes to frail elderly. As former director of the SDSU Adult Fitness Program, Dr Nichols has many years of practical and research experience in developing, administering, and evaluating exercise programs for older adults, with particular emphasis on improving balance, mobility, strength, and functional fitness to ultimately prevent falls and bone fractures. As co-investigator with the MEDEX study, Dr Nichols and the EPARC team developed and have implemented the exercise program for study participants.

Meet the MEDEX Team

Dr. Eric Lenze, the Principal Investigator of the MEDEX study at Washington University in St. Louis, completed medical school and psychiatry residency at Washington University School of Medicine. He trained in a geriatric psychiatry fellowship at University of Pittsburgh, and then underwent a research fellowship at the Late-life mood disorders center at University of Pittsburgh.


Dr. Lenze’s research focuses on treatment development and testing in anxiety disorders, depression, and co-occurring cognitive dysfunction. An author on over 130 peer-reviewed articles, reviews, and book chapters, Dr. Lenze is also a practicing geriatric psychiatrist who manages outpatients and teaches medical students and residents.

About Dr. Lenze, M.D.

Dr. Julie Wetherell, the Principal Investigator of the MEDEX study at UC San Diego, earned a B.A. at Yale and a Ph.D. in Clinical Psychology with specialization in aging at the University of Southern California. After a geropsychology internship at the VA Palo Alto Health Care System, she completed a postdoctoral fellowship at UC San Diego’s Advanced Center for Interventions and Services Research in Geriatric Mental Health.


She has been a member of the UC San Diego faculty since 2003. Dr. Wetherell has already published more than 85 peer-reviewed articles, 25 book chapters, and an edited book on late-life mental health. She is particularly interested in research on behavioral interventions for late life mental disorders.

About Dr. Wetherell, Ph.D.

Dr. Julie Wetherell and her colleagues at the University of California, San Diego and Washington University in St. Louis are conducting the MEDEX research study to find out how to improve memory and concentration in older people.


The study is supported by the National Institutes of Health and the McKnight Brain Research Foundation. We are inviting approximately 580 subjects to participate in research that will help us better understand how Mindfulness-Based Stress Reduction (MBSR), physical exercise, and health education classes influence cognition in older adults. In this study, we use the term “cognition” to refer to mental processes such as attention and memory.


The study team includes doctors, nurses, psychologists, social workers, physical and occupational therapists, and exercise scientists. All of us are committed to helping older people stay healthy, mentally and physically.
