  • 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...
  • 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.
  •  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.
  • 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...

Postdoctoral Associates

  • Courtney GilesCourtney D. Giles
    Postdoctoral Associate, Vermont EPSCoR
    Research Interests: Phosphorus biogeochemistry. I am interested in understanding the relative contribution of internal and external sources of phosphorus (P) to Lake Champlain and the influence of these P loads on lake eutrophication. I study the contribution of sediments to the internal loading of P in Missisquoi Bay through a combination of temporal and spatial assessments of sediment geochemistry, including the analysis of bioavailable and enzyme-labile organic P forms and metals. Other projects include the characterization and quantification of P associated with suspended stream sediment loads, and the use of oxygen isotopes of phosphate to identify the terrestrial and aquatic sources of phosphate to surface waters.
  • Yaoyang XuYaoyang Xu
    Postdoctoral Research Associate, Vermont EPSCoR
    Research Interests: The application and potential integration of several theories in the meta-modeling and data analysis (e.g., law of the minimum; principles of population growth; ecological synchrony concept; metabolic theory of biodiversity; environmental noise color; ecological signal resonance). Research topics include eutrophication and ecosystem management under changing climate, and understanding the complex relationships between the aquatic environment (water temperature, water clarity and macro-nutrients) and organisms (phytoplankton, zooplankton and macroinvertebrate).
