Joshua Weitz

Joshua Weitz is a Professor of Biological Sciences at the Georgia Institute of Technology, with adjunct appointments in Physics and Electrical & Computer Engineering. He joined Georgia Tech in 2007 and directs a multidisciplinary research group focused on the ecology and evolution of viruses that infect microbes.

• Education:
  • B.A. in Physics from Princeton University (1997)
  • Ph.D. in Physics from Massachusetts Institute of Technology (2003)

Research Interests center on theoretical and computational approaches to understanding virus-host interactions in marine ecosystems. His work examines how marine viruses influence microbial community structure, biogeochemical cycles, and ecological dynamics through mechanisms like the viral shunt and eco-evolutionary feedbacks.

Scientific Awards include:

• Fellow of the American Association for the Advancement of Sciences
• Fellow of the American Academy of Microbiology
• Blaise Pascal International Chair of Excellence
• 2025 Simons Collaboration on Ocean Processes and Ecology (SCOPE-ALOHA) Award

Weitz's research integrates data-driven and inverse modeling to quantify virus-induced effects on microbial communities in the North Pacific Subtropical Gyre. His group develops parameterized models of virus-host interactions for regional ocean ecological modeling.
