Primary Investigator

Ian Krajbich

Principal Investigator: Ian Krajbich

Ian is an Assistant Professor in the Departments of Psychology and Economics at OSU. Before moving to Columbus, Ian was a postdoctoral scholar at the University of Zurich, with Ernst Fehr. Prior to that, Ian spent ten years at Caltech, earning his Ph.D. in Behavioral and Social Neuroscience with Antonio Rangel, Colin Camerer, Ralph Adolphs and John Ledyard, his M.Sc. in Social Science, and his B.Sc. in Physics and Business Economics & Management.


Graduate Students

Rachael Gwinn

Rachael is a fourth-year graduate student coming from UC Davis, where she received her BA in psychology. She is interested in researching how decision making can be affected by past experience and attention. Additionally, she is interested in how personal preference, and subsequent decisions based on these preferences, can be influenced through implicit learning and neurofeedback.






Stephanie Smith

Stephanie Smith

Steph is a fourth-year graduate student in the decision psychology program. She completed her undergraduate studies in Psychology, Economics, and Mathematics at St. Olaf College in Northfield, MN. Steph is fascinated by how people make financial and consumer decisions for themselves and ultimately, how this process compares to the practice of surrogate decision-making.





Daniel Cisneros

Daniel is a Ph.D. student in the Department of Economics. His primary research interests include behavioral and experimental economics. He is interested in the ways people abstract away from rational decision-making and the impact this causes to society.






Nitisha Desai

Nitisha Desai

Nitisha is a Ph.D. student in the Department of Psychology. She received her undergraduate degree from UNC-Chapel Hill. She is interested in modeling of decision-making processes, especially moral decision making.







Nadja R. Ging Jehli

Nadja is a Ph.D. student in Decision Psychology with a Minor in Neuroscience. She received her Master degree in Behavioral and Experimental Economics from the University of Zurich where she also conducted research together with Prof. Dr. Roberto Weber. She is interested in understanding humans’ decisions in social contexts by incorporating the findings of neuroscience, psychology and behavioral economics. In doing so, she attempts to unravel the interaction of the underlying cognitive, motivational and neural mechanisms that shape an individual’s thought, perception and behavior. Her current research interests include:

1. The investigation of emotions during one’s decision process.

2. How individuals form their set of beliefs, based on their experiences and observations. How they rely on them when processing multiple alternatives and choosing an optimal course of action and eventually, how persistent they are such that one finds epigenetic evidence for it.

3. How different physiological states can potentially modulate hormonal and brain neurotransmitter dynamics and in doing so influence humans’ information processing and social decisions.
