My research focuses on computational theories of learning and decision-making. In particular, I am interested in how attentional mechanisms shape the states that humans represent and learn about in changing environments.

William James once remarked that "the greatest weapon against stress is our ability to choose one thought over another." I work on understanding such internal "choices" as attention and memory retrieval from a computational perspective: to what extent are they deliberate? How do they interact with goal setting, decision-making and learning? How flexible are the representations on which they operate?

I am ultimately interested in how answers to some of these questions can inform our understanding of mental illness.
