Biography

Jeff Moehlis received the B.S. degree in Physics and Mathematics from Iowa State University in 1993, and the Ph.D. degree in Physics from the University of California, Berkeley, in 2000. He was a Postdoctoral Researcher in the Program in Applied and Computational Mathematics at Princeton University from 2000-2003. He joined the Department of Mechanical Engineering at the University of California, Santa Barbara, in 2003, and received tenure in 2007. He has been a recipient of a Sloan Research Fellowship in Mathematics and a National Science Foundation CAREER Award, and was Program Director of the Society of Industrial and Applied Mathematics Activity Group in Dynamical Systems from 2008-2009. Jeff's research interests involve using techniques from dynamical systems theory to understand and control natural and technological systems. His application areas include neuroscience (developing algorithms for controlling neurons, inspired by deep brain stimulation of patients with Parkinson's Disease), turbulence (understanding the transition to and nature of shear flow turbulence), energy harvesting (converting vibrational energy to useful power), and collective behavior (fish schooling, social networks, group decision making).
