    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.

  • Sara Shallenberger Brown Professor at the School of the Environment

    One of Dr. Lee’s research areas focuses on mitigation of and adaptation to climate warming in the urban environment. He is establishing a large database on urban heat islands for global cities to support climate adaptation efforts. The database will include satellite-derived data layers, city morphological attributes, and data from urban weather station networks. He is working with collaborators to collect street-level temperature and humidity data, using bicycle-mounted smart thermometers, in cities in different climate zones around the world. So far, urban warming studies have been restricted almost exclusively to temperature, but humidity also affects human comfort in heatwave events. He wants to quantify the combined contribution of temperature and humidity to heat stress on urban residents.

  • Paul Turner

    Rachel Carson Professor of Ecology and Evolutionary Biology

    Dr. Turner conducts research on effects of temperature on phenotypic performance of RNA virus pathogens, such as dengue virus. While it appears that global warming is contributing to geographic range expansion of disease vectors, such as mosquitoes, less is known about whether RNA virus pathogens are generally capable of expanding their ranges alongside vectors. It is possible, for example, that only certain virus genotypes within the pathogen population are predisposed to spread, or are capable of mutations fostering spread at the leading edge of range expansion. To examine these ideas, Dr. Turner studies the thermotolerance (phenotypic performance across challenge temperatures) of RNA virus genotypes sampled from natural pathogen populations. In addition, he examines the adaptive potential of different RNA virus genotypes when challenged to evolve in tissue culture environments under elevated temperatures, as well as the ability for these viruses to replicate within live mosquitoes that are cultured at differing temperatures. Similar experiments concern other aspects of some climate change models, which predict that environmental temperatures will become increasingly stochastic in the future. Here, Dr. Turner is testing whether RNA viruses can adapt to withstand stochastic ambient temperatures, and whether their growth within live mosquito vectors is compromised by erratic temperature fluctuations. Dr. Turner’s research is highly interdisciplinary, harnessing approaches such as laboratory experimental evolution, molecular genetic and genomics analyses of wild and lab-cultured viruses, interactions between viruses and live mosquitoes, and computational approaches to studying evolution.

He has studied the seasonal drivers of respiratory disease epidemics, including the effects of climate and co-infections on disease transmission and susceptibility to developing invasive infections. He has also worked with collaborators in Brazil and New Caledonia to understand how climate and weather might influence disease patterns for several vector borne and environmental diseases. Current work seeks to understand how climate might influence disease patterns locally in the greater New York/Connecticut region and how these patterns could influence prophylaxis and vaccination strategies. He has access to several large disease databases from the United States and globally that could be used for research projects.

    Dr. Zhang is a member of the Executive Committee of the Climate Change and Health and has a major interest in reproductive health epidemiology. She has established a large birth cohort study in China to investigate effects of various environmental and other exposures and genetic and epigenetic changes on adverse pregnancy outcomes and developmental health. Influences of air pollution and climate change, as well as their joint effects with other environmental as well as psychosocial factors, on adverse pregnancy outcomes and developmental health will be studied in the cohort.
