New! The CogMod Lab is looking to accept up to 2 new graduate students for the incoming class of 2015. Visit our lab website for detailed information on how to apply. New!

Research Interests

My research centers on a joint strategy of behavioral and psychophysical studies, along with mathematical and computational modeling. I and the other members of the CogMod Lab focus primarily on visual cognition and theoretical neuroscience, but our work extends to high-level cognitive phenomena such as analogy making and problem solving. The lab website provides more detail on some current research projects.

Selected Publications

A complete list of publications (as of October 2014) is available separately, organized by outlet type, topic, or in reverse chronological order.

Branching Out

My teaching home page provides access to course syllabi, reading assignments, presentation slides, and various student resources.

A sizable portion of this site is devoted to assorted ideas of general interest: philosophy, humanism, politics, science, astronomy, aikido, ... Life is so interesting and deep, check it out!

My personal home page was meant to publish photos of my daughter and wife for the benefit of my extended family in Bulgaria. This idea, however, was made obsolete by the advent of Facebook. You are welcome to visit us at http://www.facebook.com/alexander.petrov1969

Last but not least, help support Max and other kids with short gut/short bowel syndrome and TPN-associated Liver Disease . If you know anyone with these conditions, spread the word about Omegaven. It saves lives!
