I am interested in the intersection of ocean farming and marine ecology, framed by a changing climate, and the resulting ecological and social impacts of managing both for sustainability. I work closely with ocean farmers, especially those focused on growing low-trophic level “extractive species” to assess the ecosystem services (and where present the trade-offs) of farming in the marine environment and conversely, how the marine environment impacts the quality and nutrition of ocean-farm crops. Much of this work is focused on bivalves and macroalgae (mussels, oysters and seaweed) in both temperate and tropical areas via field and laboratory methods.

Before joining the UNE in 2014, I worked with the Maine Department of Marine Resources in fisheries and shellfish management, as well as working in water quality and assessing links between watershed health and the nearshore marine environment. While studying the nearshore fisheries of Maine I became tied to the identity and deep marine heritage of Maine’s coastal communities. Prior to this I completed my M.S. graduate studies at the Nova Southeastern University Oceanographic Center (Florida) with the National Coral Reef Institute studying the reproductive ecology of high latitude coral species. Earlier still, I earned a BS degree from the University of New England in 2006 with a major in Aquaculture and Aquarium Sciences.

I grew up in the Green Mountains of Vermont, along the shores of Lake Champlain. Outside my work, you can find me spending time with my family tending our small oyster farm, surfing, camping, hiking and otherwise seeking adventure on land and sea.

Current Research

I currently conduct research with UNE Center for Excellence in the Marine Sciences (CEMS). Working closely and collaboratively with UNE faculty researchers, students, I seek to create powerful institutional and marine-industry partnerships to conduct and coordinate interdisciplinary research into the sustainability, ecology and physiology of ocean foods with a focus on th Gulf of Maine with projects in other regions periodically. 

Research Interests

Research areas of interests include: Bioremediation of land based sources of pollution via multitrophic aquaculture; techniques in non-fed, low-trophic level species aquaculture; coral reproduction and aquaculture; additive effects of acute land based pollution and climate change on nearshore benthic invertebrates; sustainable ocean food systems.
