I am a professor in the psychology department at Rutgers-Camden, and this means that my work is largely divided between research and teaching. My research emphasizes 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 experimental psychology and classes related to perception. (How do we gain knowledge about the world from our sensory systems?)  I believe that students are most interested and learn best when they apply the knowledge they are learning. To this end, I lecture very little. Instead, I expect students to learn material outside of class by reading, listening to, or watching assigned material, and we use in-class time to answer questions and apply knowledge.  For more information about my classes, including example syllabi and grading philosophy, click here.  For information about independent study, click here.  If you are a student and you want me to write you a letter of recommendation, click here.
