Alexander Ehrenberg

Staff Research Associate
Fields of Interest: 

Alex started at the Memory and Aging Center as a staff researcher in the lab of Prof. Lea T. Grinberg in 2013. There, he developed interests in the factors that influence selective vulnerability and resilience at the early stages of Alzheimer’s disease and the neuropsychiatric manifestations associated with those stages. He now has dual roles as a researcher in the Grinberg lab and as a Ph.D. candidate in the Dept. of Integrative Biology in the lab of Prof. Daniela Kaufer at UC Berkeley's Helen Wills Neuroscience Institute. His primary interests are in the evolutionary and life history factors that influence early patterns of selective vulnerability in neurodegenerative diseases. He also has research interests in natural history and comparative neurology. In this ream, he focuses on neuroethological adaptations associated with wetland ecotone systems in Carnivora, focusing on African otters with fieldwork in Malawi and the Democratic Republic of the Congo.
