I am an associate professor in the psychology department at Rutgers-Camden, and I study the relationship between visual perception and memory. How much of what you see do you remember?  And why do you remember some things better than other things? To study these questions, I collect behavioral data from humans, and then I use this data to guide the development of computational models that explain performance. You can find out more about recent publications here. On occasion, people outside of academia find this work interesting: Click here for media coverage. 

My teaching work centers on perception and experimental methods. Because we all learn best by doing, my classrooms are flipped:  students learn initially outside of class by reading, listening to, or watching assigned material, and in-class time is spent solving problems, answering questions, working on experiments, or engaging in vigorous debate.
