    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.

  • 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.

    Dr. Wang, a fungal biologist, is interested in understanding how fungi respond to environmental stimuli and how these responses evolved. Fungi exhibit huge global diversity and include many severe human pathogens. Dr. Wang’s interests include studying genetics and functional genomics of fungal growth and pathogenicity and investigating how environmental changes (including climate change), as well as human activities, would affect fungal growth and distribution. Currently he is studying dynamics of microbial communities in water ecosystems in heavily populated urban areas.

    Dr. Warren researches environmental exposures and their impact on human health, with a focus on developing spatial and spatiotemporal statistical methods to improve the understanding of underlying associations between disease and exposure. His current work seeks to improve the identification of susceptible periods during pregnancy where increased exposure to ambient air pollution more adversely impacts the developing fetus. Dr. Warren has interest in understanding how air pollution levels may be impacted by climate change across space and time, and what effect this will have on human health.

    Dr. Weinberger works to understand the epidemiology of common respiratory infections that afflict young children and the elderly and seeks to use this information to develop more optimal interventions to reduce disease burden. 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.

  • Assistant Professor

    Dr. Zang works on climate change and population health. Specifically, she is collaborating with YCCCH colleagues to better understand the impact of extreme temperature and air pollution on children's academic performance and health, using administrative data for all public schools in North Carolina. She and collaborators are also evaluating the effect of long-term ozone exposure on cognitive impairment among Chinese older adults. In the future, she is also interested in examining the impact of climate change on fertility, mortality, and migration patterns in the US and China.
