I am interested in memory, and how people make decisions based upon their memorial experiences. I have an interest in ‘basic’ face recognition/perception, as well as a more applied interest in eyewitness identification. I am also interested in metacognition – i.e., ‘thinking about thinking’ – particularly as it relates to the confidence people express about their memory-based decisions, and the relationship that confidence has to accuracy.
