The scientific process is imperfect. My goal is to make it better. To this end, I study how various factors, such as competition between scientists and study-population diversity, affect scientific inference. I am especially interested in strategies for improving theoretical progress in the social sciences.
My work is inherently interdisciplinary, drawing on research and methods from 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 have similar interests or questions about my research, please feel free to contact me via email.
