He is a multi-disciplinary dynamicist and mechanical engineer interested in the understanding, modeling, and control of complex systems. I am a research scientist at the University of California, Berkeley. I received my Ph.D. degree in mechanical engineering from the Sharif University of Technology and was a post-doctoral fellow at Florida State University where I worked with Christopher Hunter on various problems in complex fluids, kinetic theory and galactic dynamics. I have held faculty and research positions at the Sharif University of Technology, Institute for Advanced Study, Princeton, Institut d'Astrophysique de Paris, Institute for Advanced Studies in Basic Sciences, Zanjan, and Leiden University in the Netherlands. My current research centers on developing the science and technology of micro-robots, super-maneuverable underwater vehicles, integrated glass-based microfluidic chips, optimal and nonlinear control of complex systems, planet formation, and galactic dynamics. Our research on micro-swimmers and their collaborative flocks has received the National Science Foundation (NSF) award.
