Derek Powell
Postdoctoral Scholar - Stanford University


About Me

I am currently a postdoctoral scholar at Stanford University, working under Ellen Markman. I earned my PhD in Cognitive Psychology at the University of California, Los Angeles under advisor Keith Holyoak. I was born and raised in Wauwatosa, WI and previously educated in the desert at Arizona State University. I love coffee and beer and have recently become an amatuer coffee roaster and home brewer (emphasis on amatuer). I also dabble in photography.

Using experimental and computational methods, my research examines higher-order cognition with a focus on systems of belief and belief revision. I also study moral reasoning, causal learning, and research practices. Data and supplemental materials for some of my projects are available on Open Science Framework.
