Principal Investigator

Dr. Jonathan H. Grabowski

B.S. Duke University, Biology & Economics

Ph.D. University of North Carolina at Chapel Hill, Ecology

Research Areas: Ecology, Fisheries Biology, Conservation Biology, Restoration Ecology, Ecosystem Management, Ecological Economics

My research interests span issues in ecology, fisheries and conservation biology, social-ecological coupling, environmental policy, and ecological economics. I have used a variety of estuarine (oyster reef, seagrass, salt marsh, mud bottom) and marine (kelp bed, cobble-ledge) systems to examine how resource availability, habitat heterogeneity and predation risk affect population dynamics, community structure, and ecosystem functioning. Much of this work focuses on economically important species such as lobsters, cod, herring, monkfish, and oysters, and consequently is relevant for fisheries and ecosystem management. My lab also focuses on how habitat degradation and restoration influence benthic community structure, population structure, and the transfer of energy to higher trophic levels. In addition, we are interested in how fisheries management initiatives such as the design of closed areas, delineation of stock boundaries, fishing gear modifications, and quota setting impact fish population structure and fisheries productivity, essential fish habitat protection, community structure, and the social capital of stakeholders.

Theresa Davenport

B.S. Gettysburg College

M.S. Virginia Institute of Marine Science

Theresa is a benthic community ecologist interested in informing coastal restoration using targeted experimental and modeling approaches. She is examining the role of biodiversity, and/or other characteristics of resilient coastal ecosystems, in mediating the impacts of stressors on coastal habitats and their ability to function and provide ecosystem functions and services. She is currently comparing the capacity of oyster reefs with different characteristics to augment fish production. She is co-advised by Dr. Randall Hughes. For her Master’s degree at the Virginia Institute of Marine Science, Theresa examined the biological impacts of living shoreline construction on benthic biota. Prior to joining the Grabowski lab, she developed strategies for monitoring and adaptive management of restoration as part of the Natural Resources Damage Assessment (NRDA) process following the Deepwater Horizon oil spill.

Micah Dean

B.S. University of Vermont

M.S. Cornell University

Micah Dean graduated with a B.S. in Environmental Science from the University of Vermont in 1999. After completing his undergraduate studies, he worked for the U.S. Fish and Wildlife Service for a year before moving on to Cornell University to pursue a Master’s degree. During his time at Cornell, Micah studied the spatial and temporal distribution of juvenile Chinook salmon in nearshore Lake Ontario. After completing his Master’s degree in 2002, he took a job as a research scientist at the Massachusetts Division of Marine Fisheries in Gloucester. Over his 15 year career at MADMF, Micah has had the opportunity to work on a variety of fisheries issues, including cod spawning behavior, recreational discard mortality, coastal migration of striped bass, and population dynamics of forage species. Building from this base of experience, he began his PhD at Northeastern in 2015, focusing on the influence of spatial and seasonal heterogeneity on population and fishery processes for Atlantic cod. Through his ongoing role at MADMF, Micah designed and helps coordinate a bottom trawl survey that leverages an industry-science partnership to intensively sample the Gulf of Maine cod population.  The data provided by this survey offer a novel perspective on the dynamics of this important resource and form a primary data source for his dissertation research.

After the fellowship, Helen worked for New York Sea Grant as the Coastal Resilience Extension Specialist based in New York City. Her work in extension and outreach included translating and communicating relevant science of climate and weather as well as preparedness information to urban coastal communities and translating information of local urban ecological issues to, overall, inform new science research and decision-making. As a PhD student in the Grabowski Lab at Northeastern University, Helen is looking forward to enhancing her knowledge and experience, working on issues relating to coastal and estuarine ecosystems, social-ecological issues, and fisheries management.

Louise Cameron – PhD

B.S. University of St Andrews (UK)

Louise graduated from The University of St Andrews in 2015 with a BSc in Marine Biology. Her PhD research focused on the impacts of ocean acidification and warming on marine bivalves and their fisheries. She answered these questions using a combination of field studies of bivalve performance across naturally occurring carbonate chemistry gradients that can be used as a proxy for future climate change, and through tank experiments that she used to investigate how ocean acidification and warming interact to impact bivalve physiology.

Alison Frye – Professional MS Student

B.S. Bates College

Alison graduated from Bates College in 2010 with a degree in Biology. She spent several years teaching high school science before beginning her master’s degree at Northeastern within the Three Seas Program. Her research in the Grabowski Lab investigated the use of living shorelines in the form of oyster reefs to restore estuarine habitats. Working with the Town of Essex, Alison’s study focused on selecting sites where oysters could both survive and provide the greatest ecosystem services to The Great Marsh, such as erosion control and wave attenuation. In this study, she tracked the survival and growth of juvenile remote set oysters; measured sedimentation rates, sediment organic matter, and natural recruitment; and quantified the rate of marsh retreat over the past decade.
