Sofia Beas, PhD

Principal Investigator 

Dr. Beas grew up in El Paso, TX. She obtained her Bachelor’s in Science from the University of Texas at El Paso. 

She attained a Ph.D. in Neuroscience from the University of Florida in 2015, where she used rodent models to study age-related cognitive decline. 

Dr. Beas then joined the National Institute of Mental Health as a postdoctoral fellow in the Unit of the Neurobiology of Affective Memory. Her postdoctoral work focused on investigating the cellular and circuit mechanisms by which exteroceptive and interoceptive signals affect PVT neurocircuitry and drive adaptive behavior. 

Currently, Dr. Beas is an Assistant Professor in the Neurobiology Department at the University of Alabama, Birmingham.  

Hobbies: Artisanal Chocolates, Coffee, Non-Fiction books, Learning new things, Thinking about life's big questions
