Who We Are

Howard Fillit, MD, is a geriatrician, neuroscientist, and innovative philanthropy executive, who has led the ADDF since its founding. Dr. Fillit has held faculty positions at The Rockefeller University, the SUNY-Stony Brook School of Medicine and the Cornell University School of Medicine. In 1987, he joined the Mount Sinai School of Medicine, where he is a clinical professor of geriatric medicine and palliative care, medicine and neuroscience. Dr. Fillit also maintains a limited private practice in consultative geriatric medicine with a focus on Alzheimer's disease and related dementias.

He has authored or co-authored more than 300 publications and is the senior editor of Brocklehurst's Textbook of Geriatric Medicine and Gerontology. Dr. Fillit is the recipient of many awards and honors including the Rita Hayworth Award from the Alzheimer's Association. He is a fellow of the American Geriatrics Society, the American College of Physicians, the Gerontological Society of America and the New York Academy of Medicine. Dr. Fillit earned his bachelor of arts in neurobiology cum laude from Cornell University and his medical degree from the SUNY-Upstate Medical University.

Kathryn Carnazza, PhD, is a member of the ADDF's Aging and Alzheimer's Prevention program. She critically evaluates the scientific evidence regarding prospective therapies to promote brain health and/or prevent Alzheimer's disease, and contributes to CognitiveVitality.org.

Dr. Carnazza earned a doctorate in neuroscience at Weill Cornell Graduate School of Medical Sciences, where she studied the molecular mechanisms of Parkinson’s disease. She also founded and organized a graduate school course on neurodegeneration at Weill Cornell. Dr. Carnazza obtained her bachelor's degree in biology from Tufts University.

Yuko Hara, PhD, is a member of the ADDF’s Aging and Alzheimer's Prevention team. In this capacity, she critically evaluates the scientific evidence behind therapies to promote brain health and/or prevent Alzheimer's disease. She also investigates potential risk factors as well as research proposals on prevention therapies.

Dr. Hara was previously an Assistant Professor in Neuroscience at the Icahn School of Medicine at Mount Sinai, where she remains an adjunct faculty member. Her research focused on brain aging, specifically how estrogens and reproductive aging influence the aging brain’s synapses and mitochondria. She earned a doctorate in neurology and neuroscience at Weill Graduate School of Medical Sciences of Cornell University and a bachelor's degree in biology from Cornell University, with additional study at Keio University in Japan. Dr. Hara has authored numerous peer-reviewed publications, including articles in PNAS and Journal of Neuroscience.

Betsy Mills, PhD, is a member of the ADDF's Aging and Alzheimer's Prevention program. She critically evaluates the scientific evidence regarding prospective therapies to promote brain health and/or prevent Alzheimer's disease, and contributes to CognitiveVitality.org.

Dr. Mills came to the ADDF from the University of Michigan, where she served as the grant writing manager for a clinical laboratory specializing in neuroautoimmune diseases. She also completed a Postdoctoral fellowship at the University of Michigan, where she worked to uncover genes that could promote retina regeneration. She earned her doctorate in neuroscience at Johns Hopkins University School of Medicine, where she studied the role of glial cells in the optic nerve, and their contribution to neurodegeneration in glaucoma. She obtained her bachelor's degree in biology from the College of the Holy Cross. Dr. Mills has a strong passion for community outreach, and has served as program presenter with the Michigan Great Lakes Chapter of the Alzheimer's Association to promote dementia awareness.
