Dr. Fein has over 180 scientific publications, has been on numerous scientific advisory boards and has supervised over 40 graduate, postgraduate, and junior faculty in clinical research. His research (and NRI) is focused on studying the effects of aging, disease, and drugs on brain structure and function, and in developing technology to advance such investigations.
