My research focuses on how the brain perceives, processes and utilizes dynamic visual information. On a basic level I'm interested in how the brain can recognize and encode objects across motion and changes in shape from articulation. My work also focuses on the critical social information conveyed from the motion of human bodies and faces. How do we understand from motion how someone is happy or sad? How can we tell something is alive?

To answer these questions I use behavioral and neuroimaging techniques such as fMRI and diffusion imaging, and well as machine learning approaches in analysis of neuroimaging data. I also have an interest and expertise in advanced neuroimaging techniques and improving human neuroimaging methods.
