My research interests lie in examining the constraints that inhibit the retrieval of relevant memory during problem solving, and understanding the complementary roles of conscious and unconscious thoughts in problem solving.  Before joining Carnegie Mellon University, I did my PhD (Thesis title: The mechanisms underlying incubation in problem solving) and a one-year postdoc in the Psychology Department at Lancaster University in UK, examining the role of incubation and sleep in insight problem solving.  Currently, I am working with Prof. Ken Kotovsky (Department of Psychology) and Prof. Jonathan Cagan (Department of Mechanical Engineering) examining the cognitive factors that influence team problem solving performance.
