Pavan joined the lab in 2011 as an MD/PhD student, after completing a BS in Computer Science, Neurobiology and Biochemistry from University of Washington.  Pavan is a Goldwater, Gates, and Washington Scholar.  Pavan completed his PhD in September of 2014 with a thesis that focused on selection of action based on error, reward, and noise.  His work demonstrated that trial-to-trial forgetting, a property of motor memory, is the reason why adaptation is often incomplete.  Using optimal control theory, he investigated the question of hypometria and segmentation of movements in both healthy people and people with certain movement disorders.  He discovered that these behaviors were a compensation that the brain had made in response to noise in the oculomotor system.  Working with Jennie Choi, he investigated the question of why some people exhibit high movement vigor (moving their eyes with high velocity), while others exhibit low movement vigor.  He was able to link movement vigor to the reward system of the brain, suggesting that high vigor may be associated with steep temporal discounting of reward.
