Research interests

My research investigates how latent cognitive processes contribute to observable behaviors. Most of my research falls within the area of human learning and memory (e.g., implicit learning, testing effects, recognition and source memory). I approach these topics with a combination of behavioral experiments and mathematical models (e.g., signal-detection theory, multinomial processing-tree models, Bayesian hierarchical models, global memory models).
