Aaron Gruber received his Ph.D. in biomedical engineering from Northwestern University in Chicago, Illinois, writing his dissertation on computational models of working memory and its modulation by dopamine. He was a visiting scholar at the Gastby Computational Neuroscience Unit at the University College of London working under the guidance of Peter Dayan during the winter of 2003. In 2004, Aaron began a postdoctoral position with Patricio O'Donnell at the University of Maryland School of Medicine, where he used multiple electrophysiological techniques to study how dopamine and inhibitory interneurons could shape neural activity in rodent prefrontal cortex and nucleus accumbens, and how these structures synchronize during decision making. Aaron joined the faculty at the University of Lethbridge in 2009.
