Current Research:

Population dynamics, persistence, and distribution are emergent properties of animal movement behavior and the spatial configuration of habitat. Sustainable animal populations access habitats with sufficient forage resources, a diversity of mating opportunities, and suitable nesting and overwintering locations. Suitable habitat may be isolated and imbedded in urban, agricultural, and forested areas (i.e., the matrix). Individuals that can traverse the complicated matrix often do so at an energetic cost, while those that cannot traverse the matrix suffer from isolation, resource limitation, and genetic inbreeding. Habitat connectivity, either directly with corridors or functionally with ‘habitat-stepping stones,’ facilitates the efficient movement of individuals to increase population sizes and gene-flow.

 

As an insect movement ecologist, my research focuses on is on discerning animal movement patterns, and space use in fragmented landscapes to understand movement and dispersal behavior of insect species at various spatial scales. I employ multiple research methods in the field, greenhouse, and lab to address research questions related to management of pest insects and conservation of beneficial species, including radio telemetry, population genetics, stable isotope analysis, geospatial analyses, and spatial modeling. Projects are underway to study movement, dispersal, space use, and habitat suitability of monarch butterflies (Danaus plexippus), bumblebees (Bombus sp.), spotted lanternfly (Lycorma delicatula), and European corn borer (Ostrinia nubilalis).

 

Past Research:

From 2016-2022, I studied monarch butterfly movement in Midwest agroecosystems. Most notably, evidence from this work suggests milkweed and nectar resources be established within 50 m of established habitat to create a functionally connected landscape that facilitates monarch movement. From 2013-2015, I studied the host plant suitability of the European corn borer on a range of agricultural crops that vary in defensive chemistry.
