Danielle Hare, PhD Candidate
Danielle's PhD research focuses on how carbon cycling in stream ecosystems responds to climate change, specifically increasing stream water temperatures. Danielle will develop reach-and network-scale models as part of the CREWS project.
Danielle received her BS in Geology from Syracuse University and her MS in Geosciences from University of Massachusetts-Amherst, where she studied groundwater-surface water interactions in wetlands. You can read more about her research on her website.

Alaina Bisson, MS Student
Alaina's MS thesis focused on greenhouse gas dynamics at the surface-ground water interface along stream corridors. Before her MS, Alaina received her BS in Natural Resources from University of Connecticut. She is joining the Taylor Lab (Ecosystem Ecology/Biogeochemistry) at Harvard University as a Research Associate. 
Fiona Liu, BS student
Fiona graduated as a McNair Scholar and University Scholar, with a thesis focused on nitrous oxide dynamics in groundwater discharging to streams and rivers. Fiona was an undergraduate research assistant on many projects, and majored in Ecology. She joined Li Li's research group at Penn State as a PhD student. 
Marissa Naclerio, BS student
Marissa worked with our group as an Honors student majoring in Natural Resources and the Environment with a concentration in Conservation and Sustainability. Her thesis focused on the impact of hurricanes on mangrove forests in the Florida Everglades. After graduation Marissa was a Yale Conservation Scholar as part of the Early Leadership Experience. 
Caitlin Daddona, BS student
Caitlin worked as a research technician across several projects with our group and majored in Environmental Sciences and Sociology. After graduation she accepted a position with the Connecticut Department of Energy and Environmental Protection. |
