  • Henry Alegria

    Associate Professor current-project-logo

    Area of research is in the general area of fate and transport of organic pollutants.  Specific research interests and projects within this area include: Investigating the transport mechanisms of organic pollutants in soil, air and water and their exchange between these compartments; Using chiral chromatography to track the movement of organic pollutants in the environment; Correlating land-use patterns with water quality in rivers in Central America; Determining the potential impact of pollutants on sensitive coastal ecosystems (e.g. coral reefs); Investigating the potential impact of pollutants on the health of exposed populations (e.g. pesticides and farm workers, PCBs and office workers). Read more

  • Richard Mbatu

    Assistant Professor 
    Environmental Policy

    Mbatu_s1My research focus is in two interconnected areas: 1) forest resource management and policy aspects of sustainable development and climate change, and 2) the structure and function of plans, programs, bilateral and multilateral agreements and conventions dealing with forest resource management, agriculture, land use planning, and climate change. I look into human-environment interactions through the lenses of political ecology, political economy of natural resources, environmental politics, and sustainable development.

  • Chris Meindl

    Associate Professor 

    I am a geographer interested in human-environment interaction, particularly in people’s perceptions of environmental issues, especially wetlands, natural hazards, and water resources. My regional focus is on Florida, my methods are usually qualitative and archival, and my approach is often (but not always) historical. Recently, I have grown interested in environmental management and water politics. Read more

    My research focuses on wetland carbon sequestration and the role wetlands play in climate change.  I examine freshwater wetlands and mangrove systems (coastal wetlands) to assess the wetlands current contribution to the global carbon budget, and how the contribution may change as the climate warms.  These investigations are being conducted at several sites in Brazil and in the Florida Everglades. Specific research interests and projects are: Uranium and thorium series radionuclides as tracers of geological processes; organic carbon burial in wetlands; mangrove ecosystem response to sea-level change. Read more

  • Ryan P. Moyer

    Courtesy Assistant Professor, Adjunct Instructor
    Fish & Wildlife Research Institute

    My research is broadly focused on investigating fundamental biogeochemical process in coastal and marine ecosystems across a variety of temporal and spatial scales. While my major area of expertise is isotope and trace element geochemistry, I have received an interdisciplinary training in the fields of geochemistry, marine science, geology, and ecology. My primary interests revolve around carbon cycling in tropical coastal and marine ecosystems. Specific research interests include: anthropogenic carbon and its impacts on tropical ocean chemistry and calcifying organisms (ocean acidification), organic carbon cycling in coastal wetlands, and the application of stable isotopes and trace elements in coral skeletons as proxy records of past ocean chemistry. My primary analytical tools include stable isotopes of carbon, oxygen, and boron; radiocarbon; minor and trace element ratios, and organic carbon measurements.
