Curriculum Vitae
Short Bio
The King-Casas lab uses a blend of decision neuroscience, behavioral economics, and social psychology – approaches which when jointly brought to bear on complex social phenomena, provide tractable and clear answers about how humans make decisions about, among, and for one another.

The lab’s experiments have focused on inter-related questions including: How do two people trust each other? How do individuals balance their own interests with the interests of others? How do risk preferences change across the lifespan and under social influence? How does social dominance influence the way we learn from others?

King-Casas also pursues understanding of neural computations underlying decision-making abnormalities of psychopathology. Psychiatric illnesses, from substance abuse to borderline personality disorder, include primary features that can be studied as impaired decision-making in social and non-social contexts. In current and planned work, my lab leverages our normative work in these areas to investigate neural substrates that give rise to aberrant behavior.
