The scientific process is imperfect. My goal is to make it better. To this end, I study how various factors affect the efficiency and reliability of science. Currently, I am investigating how competition between scientists and study-population diversity affect scientific inference.

My work is inherently interdisciplinary, drawing on research and methods from psychology, evolutionary biology, and anthropology. If you have similar interests or questions about my research, please feel free to contact me via email.
