Joshua Weitz is a quantitative biologist interested in the structure and dynamics of complex biological systems. He received his Ph.D. in Physics from MIT in 2003 and was a NSF Postdoctoral Fellow and Associate Research Scholar at Princeton University from 2003-2006. Weitz joined Georgia Tech in 2007 where he is currently a Professor of Biological Sciences with courtesy appointments in Physics. Dr. Weitz is also the Founding Director of the new interdisciplinary Ph.D. in Quantitative Biosciences -- http://qbios.gatech.edu. Dr. Weitz is the recipient of a Burroughs Wellcome Career Award at the Scientific Interface, a JSMF Scholar Award, a Simons Foundation investigator award, and is currently funded by the NSF, Army Research Office, Simons Foundation, and Mathworks. His research group includes ecologists, mathematicians, physicists and bioinformaticians working on three major research themes: (i) quantitative viral ecology; (ii) disease dynamics; (iii) theoretical ecology. The work in the Weitz utilizes the tools of nonlinear dynamics, stochastic processes, and large-scale data analysis to interact with experimentalists.
