Research Interests:

I am broadly interested in evolutionary consequences and signatures of interactions between organisms at the molecular scale to the ecosystem scale. I employ molecular, computational, and field based practices to answer questions. As an entomologist, I focus on my research questions through the lens of insects whether exploring the interactions between adelgids and their symbionts or the phylogentic structure of insect assemblages in environments monitored for the purpose of fish conservation.
