Ralph A. Nixon, M.D., Ph.D., Director of the Center for Dementia Research at NKI, is the recipient of the Alzheimer Association’s Khalid Iqbal Lifetime Achievement Award. The award was presented at the Alzheimer’s Association International Conference on July 28th in Philadelphia. Dr. Nixon’s principal research focuses on the biology of protein clearance by endosomal-lysosomal, autophagy and calpain-calpastatin systems. His team has identified molecular defects in these clearance mechanisms central to pathogenesis of Alzheimer’s disease and related disorders and as promising therapeutic targets. Another longstanding research program focuses on the axonal transport, assembly, and turnover of neuronal cytoskeletal proteins and their dysregulation in dementia. Nixon has served on many scientific advisory boards over the years, holds eight issued patents and has authored more than 325 scientific publications.
