Welcome to my webpage. I am an applied economist and my work focuses on how economic incentives interact with psychological factors and social norms to drive individual behavior and policy-relevant outcomes. My research largely falls into one of three related areas:

  - The role of economic incentives in shaping prosocial behavior, with a focus on blood donation.
  - Understanding individual preferences for policy options to regulate morally controversial exchanges, particularly payments to organ donors.
  - Using behavioral interventions and incentives to induce behavioral change in health-related contexts, and to shed light on the mechanisms underlying that change.

My work was funded by several funding agencies, including the NSF and the NIH.
