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.
