Rebecca Irwin
Associate Professor
I am a community and evolutionary ecologist and am passionate about plants, pollinators, and their interactions. Current research projects include how pollinators and pollination are responding to environmental change (invasive species, urbanization, and climate change), exploitation of pollination mutualisms, and effects of secondary compounds on pollinators and their parasites.

Erin Eichenberger
Ph.D. student I am interested in remnant ecosystems and conserving fragmented plant communities and their pollinators. I am studying the ecology of plants and pollinators in the Piedmont prairie, a rare grassland ecosystem native to North Carolina. I aim to understand how management activities affect plants at different life stages, and how success at different life stages contributes to population growth. Website |
April Sharp
Ph.D. student I am interested in tritrophic plant-pollinator interactions and the role that pollen plays in mediating bee microbiology. My research focuses on investigating how the morphological features of pollen interact with the inner microbiome of bees and how these interactions can be applied to conservation practice🕱s. Bianca Jimenez Ph.D. student I am interested in how diseases can be transmitted from one bee species to another. My research focuses on the relationship between fecal matter size and disease transmission. The aim of my research is to determine if smaller solitary bee species are able to transmit diseases to bigger bee species and if so, at what intensity. |
Post-Docs
Selina A. Ruzi, Ph.D.
NSF Postdoctoral Fellow I am generally interested in invasion ecology, plant-insect interactions, and biodiversity. My current work has two main focuses. First, how bee diversity changes through time and urbanization using museum specimens. Second, whether the spokesperson communicating a science story influences perceptions of that story. In the past, I have worked on ant-mediated seed dispersal of pioneer tree species in Panama. Website |

Em Trentham

Kristin Conrad, MS.
Lab manager
I am interested in how warming temperatures and changing patterns of precipitation associated with global climate change may affect pollinators and pollination services, especially ecosystem services provided in crop pollination. I am also broadly interested in utilizing comparative genomics to quantify plant-pollinator interactions and networks, quantifying bee desiccation and thermal tolerances, as well as implementing ecological applications that support native pollinators in agroecosystems. My most recent research focuses on dissimilarities in bee abundance and community composition across an elevation gradient and at economically- important crop species in the seasonally- dry Pacific slope forests of Costa Rica.
