  • Serap Aksoy

    Professor of Epidemiology (Microbial Diseases)

    Research Interests
    • Trypanosomiasis, African
    • Tsetse Flies
    • Global Health

    Dr. Aksoy is interested in pursuing research at the interface of climate change and insect physiology. Incidence of vector-borne diseases has been increasing in temperate climates and feared to be influenced by climate change effects globally. Dr. Aksoy is interested in analyzing climate change impacts on key insect physiologies that affect population densities and disease transmission traits. Changes in reproductive physiology would modify insect population densities, an essential parameter for vector-borne diseases. Changes in insect immune responses would increase the survival and transmission of pathogens adversely impacting disease control efforts. Dr. Aksoy leads several large NIH-supported research and training programs on control of African trypanosomiasis in sub-Sahara.

  • Paul Anastas


    Paul Anastas is the Director of the Center for Green Chemistry and Green Engineering at Yale. His research and the research of the Center directly address climate change issues in several ways. Energy storage is one of the great challenges for renewable energy such as wind and solar. Professor Anastas’ research has developed new catalysts that can use renewable energy to split water (both fresh and seawater) in order to generate hydrogen that can be stored and used later. In addition, his research looks at ways of utilizing carbon dioxide in value added ways such as making small molecules. The center also has an integrated bio-refinery effort that seeks to develop new creators and separations to ensure the isolation of high value-small volume molecule to drive positive economics.

    • Rickettsia
    • Global Health
    • Zoonoses
    • Arenavirus

    Dr. Childs’ research focuses on zoonotic diseases, including hantavirus pulmonary syndrome (HPS), caused by a hantavirus maintained in the prairie deer mouse host, and leptospirosis, caused by leptospires maintained in the Norway rat host. Outbreaks of these diseases are driven by weather patterns and climate variation. The initial outbreak of HPS in the southwestern US followed an El Niño event that resulted in increased rainfall and an unusually warm winter. These conditions facilitated deer mouse survival and earlier vegetation growth, producing an exceptionally large mouse population. The increased potential for human-rodent contact drove the epidemic and subsequent studies demonstrated the predictive value of weather conditions for estimating the magnitude and geographic range of HPS outbreaks. Leptospires are shed in rat urine. Predictable outbreaks in tropical urban slums, such as in Salvador, Brazil, occur each year during the rainy season when people are exposed to contaminated water and mud. Additionally, severe weather events causing flooding are linked to epidemics of leptospirosis in tropical locations. Climate change, potentially resulting in increased frequency of severe weather events, will lead to marked changes, in currently unpredictable ways, in the epidemiology of these zoonotic diseases.

  • Miraj U. Desai


    community mental health; qualitative and participatory research; global health; prejudice and discrimination; philosophy of science; and South Asian studies

    Dr. Desai is interested in psychological and political perspectives on climate change. His main concern is understanding and addressing issues of climate justice, e.g., that those most affected by climate change (the global poor, islanders) are the ones least responsible for it. He has written on psychology and climate justice for the Huffington Post and was a participant at the first-ever Yale Environmental Sustainability Summit. He recently received the Certificate of Outstanding Recognition from the Yale Office of Sustainability.

  • Nicole Deziel

    Assistant Professor of Epidemiology (Environmental Health Sciences), Assistant Professor in Forestry and Environmental Studies and in Chemical and Environmental Engineering

    Dr. Deziel is leading a project related to exposure to shale gas development (“hydraulic fracturing”) and risk of childhood health outcomes. Within the context of this project is an assessment of proximity to unconventional oil and gas development and drinking water contamination and an evaluation of spatial and temporal trends of unconventional oil and gas development. She is also working with Dr. Michelle Bell at the Yale School of Forestry & Environmental Studies to explore associations between exposure to PM2.5 and O3 and risk of respiratory and cardiovascular hospitalizations and how these associations may be impacted by a changing climate.

    Dr. Fish conducts research on the impact of climate change upon vector-borne diseases. His studies on changes in the geographic distribution and severity of Lyme disease due to global warming predict minimal geographic change in risk for the US, but a potential increase in disease severity for the endemic areas of the Midwestern states. The predicted case increase for Canada has already been observed. He is currently conducting a study on climate change impact upon mosquitoes and mosquito-borne viruses in the Florida Everglades in collaboration with the U.S. National Park Service. Due to its “tropical island” nature, extreme South Florida already has several endemic tropical mosquito species and arboviruses, and more are anticipated as the region warms and becomes more tropical. Dr. Fish serves on the Steering Committee of the Yale Climate and Energy Institute and served on the National Research Council Panel Review of the 2014 National Climate Assessment.
