Alex started off in the neuropathology core at UCSF’s Memory and Aging Center in 2013 under the mentorship of Prof. Lea T. Grinberg. There, he developed interests in the factors that influence selective vulnerability underlying early Alzheimer’s disease stages and associated neuropsychiatric manifestations. Now a Ph.D. Candidate at UC Berkeley, he is co-advised by Prof. Grinberg and Prof. Daniela Kaufer and continues his focus on neurodegenerative disease vulnerability. He also has research interests in natural history and comparative neurology where he examines the evolutionary framework surrounding neurodegeneration and neurologic aging.
