Dr. Rachael Winfree

Rachael Winfree is a Professor in the Department of Ecology, Evolution and Natural Resources at Rutgers University, New Brunswick. The goal of her work is to better understand the causes and consequences of biodiversity, particularly in real-world settings and at large spatial scales. Current projects in her research group include (1) the relationship between biodiversity and ecosystem services, (2) biodiversity measurement, (3) plant-pollinator networks, and (4) pollinator conservation and restoration. Her work has been funded primarily by the National Science Foundation (NSF) and the United States Department of Agriculture (USDA), and has been published in leading scientific journals including Science, Proceedings of the National Academy of Sciences (PNAS), Ecology Letters, and Proceedings of the Royal Society of London. From 2015-2019 she was one of approximately 170 scientists worldwide (and one of approximately 20 women) on the list of highly cited researchers in the field of environment / ecology. Rachael is a Fellow of the American Association for the Advancement of Science (AAAS) and a Fellow of the Ecological Society of America. She serves on the board of directors of the Xerces Society, which has the largest pollinator conservation effort of any nonprofit. She received her Ph.D. in Ecology & Evolutionary Biology from Princeton University in 2001 and her B.A. from Dartmouth College in 1990.

Dr. Katie Turo

Katie is a USDA NIFA Postdoctoral Fellow and community ecologist who leverages quantitative and molecular tools to examine anthropogenic drivers of pollinator biodiversity, fitness, and foraging. A central theme of her work is reconciliation ecology, or the advancement of land management strategies that satisfy human needs while preserving healthy ecosystem functioning. Her postdoctoral research goal is to better understand bee’s foraging preferences in springtime and develop conservation management for wild pollinators of spring fruit crops. Katie completed her Ph.D at The Ohio State University where she studied urban pollinator conservation.

Dr. James Reilly

James is an ecological modeler who develops and analyzes mathematical and statistical models in collaboration with various members of the lab. James received his Ph.D from Cornell University in 2009.




Lucia Weinman

Lucia Weinman is a sixth-year PhD candidate. She is interested in the role of biodiversity in the functioning of plant-pollinator systems, as well as the inherent conflict between plants and their pollinators. For her dissertation, Lucia is using pollen analysis to study the pollen diets of spring-flying bee species in deciduous forest understories.  Using her data on bees’ pollen collection, she is quantifying the spatial variation in the identity of plants bees rely on for pollen. She is also comparing bees’ patterns of pollen collection with patterns of pollen transport. Lucia conducted her field work in National Parks in Michigan and Indiana. She graduated from Columbia University in 2014 with a BA in Environmental Biology.



Dylan Simpson

Dylan is a fifth-year PhD student interested in the intersections of biodiversity, population dynamics, and ecosystem function, especially in the contexts of conservation and land-use change. His Ph.D research uses population genetics to examine the structure and connectivity of bumble bee populations across land use gradients. He holds a BS in environmental science and an MS in biology.





Andrew Aldercotte

Andrew is a third-year Ph.D student interested in community ecology, particularly in inter-trophic interactions and drivers of biodiversity. He is doing his field work in Borneo where he is studying the phenology of plant-pollinator interactions in the tropical forest canopy, funded by a Fulbright Award. Andrew holds a MSc in Forestry from Bangor University and a BA in Economics from University of California, Santa Cruz.



Max McCarthy

Max is a third-year Ph.D student interested in studying floral resource use by bees and applying this information to conservation. For his Ph.D work, he is studying metapopulations of a rare specialist bee, Andrena parnassiae, in the fens of northern New Jersey. Max graduated from Tufts University, where he majored in Biology and Environmental Studies, in 2020. 



Joanna Greenwood

Joanna is a second-year Ph.D student studying the ecology of forest-associated bee species, their use of tree floral resources, and their role in pollinating trees in forests, especially Acer rubrum. Ultimately, she hopes for her work to inform integrated strategies for forest management and pollinator management. Joanna received her B.A. in biology from George Fox University in 2021.



Elyse Talley

Elyse is a first-year PhD student interested in studying the biodiversity and ecosystem services of native bee populations, particularly in landscapes heavily altered by anthropogenic change. She hopes for her research to strengthen our understanding of the drivers affecting pollinator responses to urbanization, thereby informing evidence-based strategies for conservation. Elyse received her BA in Biology from the University of Evansville in 2023.
