Ph.D., Ecology, Pennsylvania State University


I joined the Entomology and Plant Pathology Department in March 2019. I am coming to UTIA from Trinity College Dublin, in Ireland, where I completed a Marie Curie Sklodowska Individual Fellowship with Jane Stout. This was my third postdoctoral research experience: I participated in a USDA NIFA grant at Cornell University with Bryan Danforth, and an NSF DMS grant at Penn State University with Kat Shea. I have also worked at the University of Queensland in the Spatial Ecology Lab with Yvonne Buckley. My primary teaching responsibilities in the past included introductory biology and ecology and ecological modeling, but I have also helped to teach three international field courses (in Costa Rica and Kenya).

I received my PhD at the Penn State University under the supervision of Prof. Katriona Shea in the Biology Department and the Interdepartmental Graduate Program in Ecology. My research program has largely focused on the mutually beneficial interactions between plants and their pollinating insects, with a special focus on the provision of ecosystem services in agroecosystems, although I have worked in a variety of other systems, including invasive species in the Great Lakes, termites in Brazil, bees and elephants in Kenya, and birds in powerline cuts. I am particularly interested in the assembly, dynamics, and resilience of these networks of mutualistic interactions. I have mentored four graduate students as well as over a dozen undergraduate field and lab assistants, and have served on one graduate committee. Undergraduates have played an integral roles in many of my studies and are represented as coauthors on five of my manuscripts. I have also mentored five students from underprivileged inner city high schools and worked with three undergraduates that were part of a program to increase diversity in STEM. Strengthening international collaborations is also one of my major focuses. I look for win-win scenarios in teaching, research, and conservation.

I currently am accepting graduate students. I am interested in internally motivated students and others who feel comfortable working well past the minimum target. Please contact me if you are interested in learning more about research opportunities in my laboratory.


Pollinators provide critical pollination services and yet they are threatened by a suite of hazards, including habitat loss, pesticide application, parasites and pathogens. In agricultural systems, insect pollinators ensure the production of crop yield, but are also threatened by the intensification of agricultural practices. One of my primary focuses is thus identifying mutually beneficial scenarios between agriculture and conservation. For example, we demonstrated that communities of wild pollinators provide the majority of the pollination services in apple orchards in the Finger lakes region of New York. This allowed some farmers to save money as they no longer had to rent honeybee hives. However, the availability of wild pollinators on the landscape is directly linked to the availability of natural habitat, including weedy edge habitats around agricultural fields. Understanding the role of this weedy habitat in the health and nutrition of pollinators will be key to the future of sustainable pollination services that are not dependent on a single species. Another fundamental focus of my research is exploring the ways in which networks of mutualistic interactions form, how they respond to perturbations, and whether we can manage them through applied actions. This involves developing theoretical models to provide testable hypotheses, complemented by experimental manipulations of network structure. I have previously explored the role of diffuse coevolution in structuring these interactions, as well as the influence of disturbances such as species invasion and agricultural runoff on network structure.


  • How do we identify win-win scenarios between conservation and agriculture?
  • How do networks of interactions form between plants and pollinators?
  • What are the patterns and processes that operate on these networks?
  • Can we manipulate and manage complex networks of species interactions?
  • Can we quantify diffuse coevolution acting on the interactions between plants and pollinators?

Extension and Outreach Focus

Both mentoring and outreach are an important component of my teaching responsibilities. In particular, I enjoy teaching students (of all ages) in field environments. I have had the privilege of helping to teach three separate international field courses (twice in Costa Rica, once in Kenya), but I also regularly participate in field trips and outings on a local scale where I can teach both students and people of all ages about biotic interactions.
