Dr. Joshua Weitz is a quantitative biologist interested in the structure and dynamics of complex biological systems. He received his PhD in Physics from MIT in 2003 and was a NSF Postdoctoral Fellow and Associate Research Scholar at Princeton University from 2003-2006. Dr. Weitz joined Georgia Tech in 2007 where he is currently an Associate Professor of Biology with courtesy appointments in Physics and Bioengineering. Dr. Weitz is the recipient of a Burroughs Wellcome Career Award at the Scientific Interface and is funded by the James S. McDonnell Foundation, NSF, and DARPA. His research group includes ecologists, mathematicians, physicists and bioinformaticians working on four major research themes: (i) viral dynamics at the molecular, population and evolutionary scales; (ii) quantitative systems biology and bioinformatics; (iii) structure and function of vascular networks; (iv) theoretical ecology and epidemiology. The work in the Weitz group is primarily theoretical in nature, and utilizes the tools of nonlinear dynamics, stochastic processes, and large-scale data analysis to interact with experimentalists.
