  • Jason StockwellJason Stockwell
    Director of the Rubenstein Ecosystem Science Laboratory; Associate Professor of Aquatic Ecology in the Rubenstein School of Environment and Natural Resources | |
    802-656-3009 (campus); 802-859-3095 (laboratory)
    Research interests: My research interests focus broadly on food web dynamics, with specific interests in how animal behavior and environmental conditions affect trophic interactions. I work in systems ranging from small, hyper-eutrophic ponds to large, deep oligotrophic lakes, and on organisms ranging from phytoplankton to apex piscivores. My active areas of research include the influence and impact of diel vertical migration on invertebrate population structure, how cyanobacteria blooms influence energetic pathways, the impact of spatial resource subsidies on winter food web interactions, and the role of environmental disturbance on phytoplankton biodiversity.

  • Breck BowdenWilliam "Breck" Bowden
    Professor & Patrick Chair of Watershed Science & Planning/ Director of: Water Resources and Lake Studies Center/Lake Champlain Sea Grant/Northeastern States Research Cooperative Theme 1 | |
    Research Interests: My research focuses on interactions between hydrological and biogeochemical processes, especially as these processes are influenced by land use practices and land cover characteristics at catchment scales. I work in two different but related areas. In Vermont, my research focuses on management of stormwater impacts from development on urban streams. In Alaska, my research focuses on understanding climate change impacts on arctic streams. In both areas, my research is designed to improve the uptake and use of science knowledge by resource managers, policy makers, and community stakeholders. Learn more about my current research...
  •  J. Ellen MarsdenEllen Marsden
    Professor; Chair of the Wildlife and fisheries Biology Program in the Rubenstein School of Environment and Natural Resources |
    Research Interests: Much of my research relates to restoration of coldwater fishes, particularly lake trout and lake whitefish, and biology of exotic species in the Great Lakes and Lake Champlain. My lake trout research is focused on spawning behavior and early life history, and has recently extended to the introduced population in Yellowstone Lake. I have worked on several projects aimed at developing more effective and ecologically sustainable strategies for sea lamprey control. I am currently working with graduate students on thiamine deficiency in lake trout fry, and on the effects of lake habitat fragmentation on fish movements and genetic sub-structuring of fish populations in Lake Champlain.

  • Jana KraftJana Kraft
    Assistant Professor, Department of Animal Science
    Research Interests: Dr. Kraft's research at the interface of animal science and human nutrition integrates ruminant nutrition and utilization of animal models to determine factors influencing the nutritional quality of ruminant-derived fats/fatty acids and their role in prevention and treatment of the metabolic syndrome. The overall objective of Dr. Kraft's research program is to gain a better understanding of how lipids and bioactive fatty acids influence established and emerging risk factors/biomarkers linked to the metabolic syndrome, especially as it relates to the impact of maternal lipid and fatty acid consumption during pregnancy and lactation as a determinant of lifelong well-being and risk of disease development. Another area of her research includes the lipid and fatty acid analysis of numerous matrices such as oils/fats, feed, food items, tissues/organs, blood components (e.g., plasma, erythrocyte membranes), and ruminal/intestinal digesta. Current research efforts focus on the analysis of the trans-fatty acid content and profile of food items in a large scale survey to establish a comprehensive database accessible to academia and industry.
  • Suzanne LevineSuzanne Levine
    Associate Professor, Rubenstein School of Environment and Natural Resources; Coordinator, Aquatic Ecology and Watershed Science M.S. Concentration
    Research Interests: Food web and nutrient limitation studies in Lake Champlain, examination of stable isotope patterns in lakes, remote sensing of cyanobacterial blooms, and paleolimnological investigations of lake's response to changing land use.
  • Andrea LiniAndrea Lini
    Associate Professor, UVM Department of Geology; Director of UVM Environmental Stable Isotope Facility and UVM Linmnogeology Laboratory
    Research Interests: My research focuses on stable isotope geochemistry, with particular emphasis on paleolimnology/limnogeology, paleoclimatology, and biogeochemistry. Active areas of research include using lake sediments to study the response of lake ecosystems to climate change, extreme hydrological events, and cultural eutrophication.
  • Donna ParrishDonna Parrish
    Research Professor, Rubenstein School of Environment and Natural Resources; Unit Leader, Vermont Cooperative Fish & Wildlife Research Unit
    Research Interests: Restoration of native fishes, sea lamprey control, acoustical sampling, and bioenergetics
  • Andrew SchrothAndrew Schroth
    Research Assistant Professor in Geology; Research on Adaptation to Climate Change (RACC) - Lake Processes Group Team Leader; Lead Scientist for Vermont-Northeastern Water Resources Network (NEWRNet)
    Research Interests: I am a low temperature geochemist with interdisciplinary research interests spanning the crossroads of geology, chemistry, biology and hydrology. My research has focused on understanding the evolution of biogeochemical systems in New England, New York, Montana, and Alaska in the broad context of environmental change. The overarching aim of my research is to describe geochemical processes occurring at the earth’s surface with a general focus on nutrient and pollutant mobility and cycling on present day to glacial/interglacial timescales. Specifically, my goal is to understand how biogeochemical systems are affected by global or regional environmental change such as acid and metal pollution, deglaciation, shifting tree species distribution, evolving atmospheric composition, land use modification and changes in climate patterns. Locally, I am currently leading 2 large-scale NSF-funded efforts that seek to understand the drivers of water quality and ecosystem health in Lake Champlain (RACC-Q1) and its watershed (NEWRNet) in the context climate and land use change. I also have an active research focus studying the role of glaciers in delivery of the micronutrient iron (and other trace metals) to the Gulf of Alaska. More information on my research interests...

  • DongJoo JoungDongJoo Joung
    Postdoctoral Research Associate, Vermont EPSCoR
    Research Interests:Aquatic biogeochemistry of nutrients, trace elements and carbon. My primary focus of research is to understand the behavior of those chemicals in various environments (eutrophic lake, estuary, and open ocean) as well as in relation to climate changes. Also, I study environmental pollution (e.g., oil spill) dealing with heavy metals and polycyclic aromatic hydrocarbons (PAHs).
