Teaching Interests:

I enjoy teaching students to think about the brain as a computer and to think about life as a series of probabilistic events. In practice, this means I teach courses related to cognition and statistics.


Research Interests:

I am interested in how visual sensation becomes a robust working memory and in understanding forgetting, particularly in relation to multitasking impacts on working memory performance. I use behavioral experimentation, laboratory & online data collection, mathematical process modeling, and Bayesian estimation to explore questions related to basic theory and practical application.
