My main research interests lie in the area of human memory. Most of my recent research has been concerned with signal-detection and dual-process models of recognition memory. Some of this research is focused on the psychological modeling of recollection and familiarity (the two component processes of recognition), and some is focused on the neuroanatomical basis of these two proceses. In a separate line of research, I investigate the nature of forgetting and its possible relationship to the consolidation of memory. My Curriculum Vitae is mostly up to date, and PDFs of some of my recent publications can be found below.
