Peter Kvam is an Assistant Professor in the Psychology Department at The Ohio State University. He received his B.S. in Psychology and B.A. in Mathematics and Sociology from Indiana University in 2012 and his Ph.D. in Psychology from Michigan State University in 2017. After visiting positions at the Max Planck Institute in Berlin and the University of Tasmania, he completed postdoctoral fellowships at Indiana University and The Ohio State University in 2017-2019. He was previously a faculty member at the University of Florida from 2019-2024 before joining the department in 2024.

Research Interests

My work investigates the cognitive mechanisms underlying many types of decisions, ranging from visual perception to judgments about the value of complex multi-attribute consumer products. His current focus is on how people navigate complex, dynamic, multi-alternative and continuous decisions – such as bidding for homes in competitive housing markets where options appear and disappear over time. As part of this effort, he uses machine learning and artificial intelligence to test and create computational models of human behavior – allowing us to develop new theories of latent (cognitive, neural) processes in a data-driven way.
