Dr Gabriel Tillman

Biography

Gabriel Tillman was awarded a Bachelor of Psychology (Honours I) and a Ph.D. in cognitive psychology from the University of Newcastle. Following his Ph.D. Gabriel worked at Vanderbilt University as a postdoctoral research fellow.

His interdisciplinary research unites advanced statistical analysis techniques and methodology with many different fields of cognitive psychology. A focus of his research involves using mathematical models to learn more about how people make simple perceptual decisions. More recently he has worked on understanding the neurophysiology that carries out the mental processes of decision making.

At ACAP, Gabriel is investigating the relationship between decision processes and negative emotional states such as depression, anxiety, and stress. One goal of this work is to determine how these negative emotional states affect decisions people make.
