Nicole Rafferty

Assistant Professor

Hellman Fellow (2020-2021)



Postdoctoral Associates

Natasha de Manincor

Ph.D., University of Lille

Natasha is a community ecologist passionate about fieldwork, native bees and hoverflies. She is interested in studying the structure and functioning of plant-pollinator interaction networks and how they vary in space and time. The aim of her PhD was to understand and predict the effects of environmental changes on plant and pollinator communities by studying plant-pollinator associations along an environmental gradient, using an integrative approach that combined fieldwork observations and sampling, greenhouse experiments and statistical analyses. She is also interested in using pollen analysis and non-visual plant traits, such as volatile compounds, to improve our knowledge of how plant-pollinator associations are structured in different ecological contexts.

In the Rafferty Lab, she will study the effects of climate change on plant-pollinator interactions and how warming temperatures affect plant and pollinator phenology, traits and fitness, combining both greenhouse experiments and of course…fieldwork!


Alessandro Fisogni

Ph.D., University of Bologna


Alessandro is interested in studying different aspects of pollination ecology. During his PhD he approached this subject from a plant-centered point of view, studying the mating systems of three focal plant species and the efficiency and behavior of their pollinators. During his Postdocs he studied plant-pollinator interactions at the community level, with particular focus on the structure of plant-pollinator networks and how they change in time and space. He is also interested in bee taxonomy and in the conservation biology of wild plants and pollinators. During his academic career he has had the opportunity to work in different research groups and environments in Italy and France, and he is now excited about this new collaboration in the Rafferty Lab to expand knowledge about the relationship between climate change and plant-pollinator interactions.


Graduate Students

Andrea Keeler

Ph.D. Candidate in EEOB

Andrea is interested in the effects of global climate change on ecological communities. She is particularly interested in soil microbe-plant interactions, and how alterations in the phenology and distribution of these mutualists may impact interaction strength and community structure.


Elijah Hall

Ph.D. Candidate in EEOB


Elijah is interested in how global change impacts plants and pollinators. He is especially interested in community-level phenological patterns, the role of pollinators in plant reproductive success, and how those relationships change over space and time.

Chris Cosma

Ph.D. Candidate in EEOB


Chris is interested in how ecological communities respond to global change, and how we can apply our understanding of species interactions to biodiversity conservation. He is particularly interested in the effects of global climate change on plant-pollinator interactions, especially those involving nocturnal Lepidoptera.

Annika Rose-Person

Ph.D. Candidate in EEOB


Annika is interested in how anthropogenic global change affects community interactions. She is specifically interested in the links among underground plant-fungi interactions and pollinator communities, as well as how shifts in plant and fungal distributions may affect their connections.
