My name is Sheen Su (Yi-Hsin Su, 蘇誼炘). I am a PhD candidate in Psychology at the University of California, Berkeley. I began my doctoral training at Brown University, where I studied Cognitive Science, before moving to Berkeley with my advisor. Before beginning my PhD in the United States, I was a graduate student researcher in the Modeling and Informatics Lab at National Taiwan University. Earlier in my career, I worked as a semiconductor engineer at Taiwan Semiconductor Manufacturing Company (TSMC) before transitioning to the study of human cognition.

My research interests lie at the intersection of decision-making, motivation, and metacognition. 

My current research focuses on people's meta-decisions. In everyday life, we often decide not to decide—by opting out of voting (see this), postponing purchases (see this), or delegating choices to AI agents (see this). Using laboratory and online experiments, survey research, and computational modeling, I investigate when and why people make these meta-decisions and how we can design interventions to reduce maladaptive meta-decisions for both individuals and society.
