Environmental Sciences

The Department of Environmental Sciences conducts fundamental and applied research in diverse areas related to soil and water quality, arthropod vector-borne diseases, aquatic invasive species, and microbial ecology.  


The Department’s Environmental Chemistry group studies the behavior of chemical contaminants in the environment, including their binding to soil particles, their biological availability in soil, mechanisms of their natural breakdown in soil and water, and novel physical and chemical methods for their removal or destruction in soil and water. It also examines issues in the chemistry natural processes in the environment. Department scientists associated with the Center for Vector Biology and Zoonotic Diseases are studying the molecular evolution, epidemiology, vector-host interactions and ecology of pathogenic viruses, with the goal of reducing the risk of infections in humans and domesticated animals. Department scientists in the Invasive Aquatic Plant program are examining the ecology of invasive aquatic plants as a function of water chemistry and habitat, as well as evaluating methods for the control of invasive plants. The Department also has a research program in environmental microbiology involving carbon cycling in soils and the microbiome of insect vectors of diseases. Lastly, staff scientists are studying the molecular mechanisms of host specificity enabling the parasitic behavior of microsporidia.


The Department also runs the Connecticut Mosquito and Arbovirus Surveillance Program, which monitors transmission of viral diseases such as West Nile and eastern equine encephalitis; the Invasive Aquatic Plant program, which surveys aquatic vegetation and water chemistry in Connecticut’s freshwater ponds and lakes and develops and conducts management strategies for controlling invasive species; the Tick Testing Laboratory, which has an active testing program for pathogens linked to human diseases, such as Lyme Disease and others; and the Soil Testing Laboratory which analyzes samples from farms, homes, and commercial grounds for nutrient levels, and then recommends steps to improve soil fertility.
