The Weitz group is interested in the structure and dynamics of complex biological systems. The primary mission is to understand how viruses transform human health and the fate of our planet.

The research group includes physicists, computational biologists, mathematicians, and bioinformaticians working on three major research themes: (i) viral dynamics at the molecular, population and evolutionary scales; (ii) theoretical ecology and evolutionary biology; (iii) disease dynamics and epidemiology. The work in the Weitz group is primarily theoretical/computational in nature, and utilizes the tools of nonlinear dynamics, stochastic processes, and large-scale data analysis to interact with experimentalists.

Examples of recent and ongoing projects include studies of viral-host infection networks, dynamics of complex viral-host communities, the spread and control of infectious diseases, and the link between game theory and strategic behavior of viruses and microbes.
