My research interests are in disease ecology, marine ecology, and invasive species ecology. I’m broadly interested in how environmental change affects species interactions, and how trade-offs constrain adaptation to changing conditions. Interactions between parasites and hosts have been a focus of my work, and I use examples from parasite ecology to illustrate a broad range of ecological concepts in my teaching.

Most of the organisms I study are marine invertebrates like Littorina snails and the invasive shore crabs Carcinus maenas (European green crab) and Hemigrapsus sanguineus (Asian shore crab). Recent projects have focused on how these organisms adapt their immune defenses (behavioral and physiological) to scale with local levels of parasite infection risk. Students with an interest in host-parasite relationships and marine community ecology are welcomed to contact me about possible research opportunities.
