As a social psychologist and behavioral scientist, I study the equilibrium of forces--from the individual, the group, and the social environment--driving long-term behavior and attitudes in the real world. My primary area of research is social psychology and the interplay of psychology and economics, centered around the overlapping themes of interconnection and inequality. My program of research is founded on the idea that if we understand the dynamic interactions of social forces, we may be able to shift behavior in an enduring way, rather than influencing one-time deviations from a pattern. Specifically, I employ canonical and emerging methods and theories to investigate social and group influence on behavioral and attitudinal changes.

Some of my current research questions ask: How can groups motivate us, and sustain behavior change? How do we respond to inequality and hierarchy, and what’s the impact of resource scarcity and inequality on people’s decision processes and psychological outcomes? How does diversity impact our performance and subjective experience? How do we design psychological tools to nudge people into adopting more desirable behavior?

I’m a broad thinker, and also an active promoter of multidisciplinary collaboration. In the meantime, I keenly follow the Lewinian tradition of being a practical theorist.
