Research Interests

I particularly enjoy thinking about biodiversity at the species level, where my research explores ways to discover, manage and conserve species.

I study insects, a group with extensive species diversity where I use evolutionary theory to frame questions about species differences; and I explore those differences using methods in molecular systematics and experimental biology. A long-term goal of my research is to develop a vertically integrated view of how species-diversity information is generated, accessed and applied throughout the sciences. Because such a view is multidimensional, I work with several study systems.

I explore methods for species delimitation using pine-feeding armored scale insects (Hemiptera:Diaspididae), and species conservation using tiger beetle (Coleoptera:Carabidae) physiology and behavior. I’m also interested to find intersections between academic and applied research. My current work explores population genetic and phylogeographic variation of two moths: the Winter Moth (Lepidoptera:Geometridae), and the Gypsy Moth (Lepidoptera: Lymantriidae), both of which are non-native forest pests.

About Me

The multiplicity of ways to exist as an organism – fascinates me. As a budding diversity junky growing up in urban New Jersey, I discovered bizarre biodiversity at the natural history institutions in an around New York City. These experiences inspired me to work training marine mammals at New York Aquarium, as well as in Zoo Pathology at the Bronx Zoo. While at the zoo and aquarium, I saw ways that their history impacted current practices, and this awareness of institutional evolution made me curious about organic evolution.
