I am a multi-disciplinary dynamicist interested in the understanding, modeling, and control of natural and engineered systems. I am currently a Visiting Scholar at UC Berkeley and Professor of Mechanical Engineering at Sharif University of Technology. I received my Ph.D. degree in mechanical engineering from Sharif University of Technology in 1998 and was a post-doctoral fellow at Florida State University (2002-2004) where I worked with the late Prof. Christopher Hunter on various problems in complex fluids, kinetic theory and galactic dynamics. I have held research positions at the Institute for Advanced Study, Princeton, Institut d'Astrophysique de Paris, Institute for Advanced Studies in Basic Sciences, Zanjan, and Leiden Observatory in the Netherlands.
