Greg Dwyer
Principle Investigator
Greg is a professor in the Ecology & Evolution department at the University of Chicago. His research is focused on the ecology and evolution of infectious diseases, and especially on how mathematical models can help us understand disease dynamics.

Jiawei Liu
PhD Candidate

Jiawei uses mathematical models to study the interaction between a fungal and a viral pathogen in gypsy moth caterpillars, and the role of climate change in their competition.

Katie Dixon
PhD candidate

Katie combines transmission experiments in the field with mathematical modeling to test how host tree species effects transmission for different virus species in Douglas-fir tussock moth caterpillars. Katie’s website

Will Koval
PhD candidate
Will is broadly interested in how the dynamics of host dispersal and spatial population structure influence the dissemination and competition of pathogen communities.

Sophia Horigan
PhD student
Sophia uses mathematical models and field data to understand disease dynamics in the broader frame of management and climate change. Her research focuses on competition and coexistence between a fungal and viral pathogen in the gypsy moth.


Recent Lab Alumni

Post-Doctoral Researchers

Spencer Carran
Spencer uses theoretical and computational approaches to understand disease dynamics and guide management policy, previously in the context of human infectious disease and more recently for microbial control of Douglas Fir tussock moth.

Joe Mihaljevic
Working with the US Forest Service, Joe is using experiments and modeling to improve microbial control of the Douglas-fir tussock moth
