Rachel Penczykowski is broadly interested in the ecology and evolution of host–parasite interactions, and how ecological context affects the risk of infection and consequences of disease for hosts.
Penczykowski's research involves a combination of observational studies of natural populations and communities, manipulative experiments in the field and lab, and mathematical models. She has employed these complementary approaches to study host–parasite interactions in both aquatic and terrestrial ecosystems, and her current research focuses on wild populations of herbaceous plants and their pathogens.
Penczykowski has held postdoctoral appointments at the University of Wisconsin-Madison and at the University of Helsinki, Finland.
