Tim Pleskac, Ph.D. (Principal Investigator)

I am a professor at the Department of Psychology and a Senior Scientist at the Cofrin Logan Center for Addiction Research & Treatment at the University of Kansas. I study how people make judgments and decisions; how these processes shape behavior at the individual, group, and organizational level; and how we can help people make better judgments and decisions. I investigate these questions with computational modeling and methods from the behavioral, cognitive, and neuro- sciences. When I’m not at my desk you can find me running, biking, rowing, or out in the woods. In a parallel world, I own my own bike shop in the Midwest.

Xiaohong Cai (Graduate Student)

I am a graduate student in KU’s Brain, Behavior, and Quantitative Science PhD program. My research interests broadly touch on judgement and decision making. For now, my passion is understanding the process of judgement and decision making in adaptive environments with computational modeling and other quantitative methods. My dream is to come up with psychological fomulas so that I am able to do research on the grass along the river with pencils, papers, and my latte.

James Adaryukov (Graduate Student)

I am a graduate student in the Brain, Behavior, and Quantitative Sciences PhD program. My research is broadly focused on decision-making in social environments, more specifically on the effects of social information vs. social pressure/competition. I aim to address these questions through statistical modeling and data science. Outside of work I enjoy creative writing (short stories and poetry), making perfumes, hiking, and reading.

Sergej Grunevski (Lab Manager)

I graduated with my B.S. in Behavioral Neuroscience from the University of Kansas in 2019. I am broadly interested in investigating clinical issues (e.g., substance use and mental disorders) using rigorous psychological science (e.g., behavioral, cognitive, and physiological methods). I am currently working with Dr. Tim Pleskac on judgment and decision-making projects as well as with Dr. Richard Yi on behavioral economic projects examining health-related behaviors. In my spare time, I like to keep up with politics and stay in touch with relatives back home in Macedonia.
