The scientific process is imperfect. My goal is to make it better. To this end, I study how different factors (e.g. competition, study-population diversity) affect the efficiency and reliability of science. I am especially interested in formal modeling as a tool to improve theory in the social sciences.

My work is inherently interdisciplinary: I use a range of approaches (e.g. theoretical simulations, lab experiments, cross-cultural studies) and draw on research from diverse disciplines, including psychology, evolutionary biology, and anthropology. This means that I typically wake up and go out to work in the uncanny valley (Nettle, 2018). If you are interested in my research, please feel free to contact me via email.

In January 2019 I will move to the Netherlands for a 4-year postdoc, working with Daniel Lakens at the Eindhoven University of Technology.
