Biography

Mark Lescroart joined the Cognitive & Brain Sciences group in the department of psychology at the University of Nevada, Reno in the spring of 2018. He got his Ph.D. at the University of Southern California working with Irving Biederman and did postdoctoral research with Jack Gallant at UC Berkeley. He is originally from San Jose, California.

Research Interests

The goal of Dr. Lescroart's lab is to understand how our brains transform patterns of light on our retinas into useful information about the world. The lab is specifically interested how different areas in the brain provide information about the identity and shape of objects, the structure of space, and the types of actions (such as running, jumping, and throwing) performed by humans around us. Dr. Lescroart pursues these questions by making computational models of brain responses measured by fMRI. These models predict how the brain will respond to a wide variety of visual stimuli. Models developed by the lab can also be used to decode the image or movie clip that elicited a given visual response in the brain.
