Andrew Delamater came to Brooklyn College as an assistant professor of psychology in 1994. He became associate professor in 2000 and full professor in 2008, and was made a Brooklyn College Tow Professor in 2014. Prior to that, he was visiting assistant professor at Indiana University, Bloomington (1990-91), and postdoctoral research fellow at the University of Pennsylvania (1991-94). Since 2007, he has been fellow of the Association for Psychological Science, as well as the Eastern Psychological Association, and he has served as associate editor, Quarterly Journal of Experimental Psychology; consulting editor, Journal of Experimental Psychology: Animal Behavior Processes; Psychonomic, Bulletin, and Review and Learning & Behavior; and president of the Eastern Psychological Association for the 2012 meeting. He has just become President-Elect of the Pavlovian Society for its 2016 meeting.

Delamater's research interests are directed toward an understanding of basic learning processes, particularly as they are revealed in simple Pavlovian and instrumental learning paradigms with laboratory animals. His focus is on understanding, both at the psychological and neural systems levels of analysis, how organisms represent the causal structure of their environment with special interests in the extinction of acquired behaviors and in the mechanisms involved in reward processing.
