The scientific process is imperfect. My goal is to make it better. To this end, I study the forces that shape how scientists do their work and make inferences from the populations that they study. Much of my research focuses on how incentive structures affect the efficiency and reliability of science. I also have long-standing interests in evolutionary approaches to human behavior and in formal modeling as a tool to improve theory in the social sciences.
My work is inherently interdisciplinary - I use a range of approaches (theoretical simulations, lab experiments, cross-cultural studies) and draw on research from diverse disciplines, including psychology, evolutionary biology, anthropology, and economics. This means that I typically wake up and go out to work in the uncanny valley (Nettle, 2018).
I am currently a postdoctoral researcher working with Daniel Lakens at the Eindhoven University of Technology. This 4-year position is funded by a VIDI grant from NWO, and is part of a larger project to improve the reliability and efficiency of psychological science.
