Hi, my name is Aaron! I am interested in the process individuals undergo when making decisions under risk and uncertainty, specifically the potentially relevant situational, and psychological factors. I also try to improve our understanding of humans' perception of uncertainty, and how people react to different types thereof (e.g., epistemic and aleatory).

On the other hand, I am working on statistical and methodological questions. Specifically, I investigate how we can assess psychological processes in a situation itself, using ecological momentary assessments (EMA) and think-aloud protocols. Finally, I am intrigued by the difference between estimation and prediction for drawing inference, and modeling-approaches from complexity science.

Outside of these main focus areas, I have a broad interest in topics from cognitive and social psychology, including collective intelligence, group processes, heuristics and biases, deception, or opinion dynamics.
