My research focuses on river chemistry to improve understanding of climate-sensitive ecosystems. River chemistry provides a snapshot of environmental conditions across watersheds—much like a blood sample informs about a patient’s health—and helps to understand how those conditions, in turn, influence coastal ocean ecosystems.

As a Research Scientist, I collaborate on Arctic watershed monitoring to study how climate-related disturbances like permafrost thaw, wildfire, and human activity affect carbon, nutrients, and mercury. I also work locally in the Buzzards Bay watershed on ecosystem health and stewardship.

My passion for environmental stewardship stems from a lifelong connection to the outdoors, which I share with my family. I earned my Ph.D. in ecology from the University of Alberta and led research as a National Science Foundation Earth Sciences Postdoctoral Fellow at Harvard University and Woodwell Climate.
