      Dr. Deziel obtained a Master’s of Industrial Hygiene and Doctorate in Environmental Health from the Johns Hopkins Bloomberg School of Public Health. Her research is focused on applying statistical models, biomonitoring techniques, and environmental measurements to provide comprehensive and quantitative assessments of exposure to traditional and emerging environmental contaminants in population-based studies. Her research uses a combination of large, administrative datasets and detailed community-focused studies to advance understanding of environmental exposures to chemicals, particularly carcinogens and endocrine disruptors. This research also serves to illuminate exposure mechanisms underlying associations between environmental chemicals and disease, thereby informing more effective policies to reduce exposures and protect public health. Dr. Deziel's contributions have been directed at two main areas: (1) exposure and human health impacts of unconventional oil and gas development (“hydraulic fracturing”) and (2) residential exposure to chemicals in common consumer products (e.g., pesticides, flame retardants) and cancer risk (particularly thyroid cancer). In addition, she consider disproportionate burdens of exposures (“environmental justice”) and the combination of environmental and social stressors in the context of her work.

      Dr. Brian Leaderer is the Susan Dwight Bliss Professor Emeritus of Epidemiology in the Department of Environmental Health Sciences at the Yale School of Public Health and Professor Emeritus of the Yale School of the Environment. He is also a Senior Research Scientist at the Yale Center for Perinatal, Pediatric and Environmental Epidemiology (the Yale CPPEE, or the "Center"), which he co-directed for 18 years.  In his role as the Deputy Dean at the Yale School of Public Health for over 14 years (during which he was also Interim Dean for 2 years), he oversaw Faculty Affairs including the Appointments and Promotion Committee and Faculty Mentoring Program. He has served on several Committees and Review Panels (NRC, EPA, HEI, etc.).  Dr. Leaderer's research interests, resulting in over 300 publications, are interdisciplinary in nature with a focus on assessing exposures (measured and modeled in both environmental chamber and field studies) to air contaminants (indoor and outdoor) and assessing the health impact resulting from those exposures in epidemiological studies. Over the past 30 years, he has been Principal Investigator on numerous research grants (totaling approximately $40 million). Several of these grants have been large epidemiologic-based grants (R01s) centered on the role of environmental and genetic factors on the respiratory health of children with particular attention to their role in the development of asthma and asthma severity.  He has collaborated with colleagues from several disciplines at the Yale CPPEE for over 30 years on several epidemiologic studies examining the impact of pollutants on perinatal and pediatric outcomes. With funding from the National Institute of Environmental Health Sciences (NIEHS), he investigated the relationship between exposures to indoor levels of nitrogen dioxide, traffic contaminants, and the exacerbation of asthma in 1,401 children (in the STAR Study).  The findings from this study resulted in another NIH-funded (NIEHS) grant to conduct a double-blind, randomized control, triple cross-over design intervention trial in urban homes of asthmatic children to examine the efficacy of reducing exposure to indoor levels of PM2.5 and NO2 on reducing asthma severity.

      Caroline H. Johnson, PhD, is an Associate Professor of Epidemiology (on term) in the Department of Environmental Health Sciences at Yale School of Public Health. She graduated from Imperial College London in 2009 with a PhD in Analytical Chemistry. Since then she has held postdoctoral and staff appointments at the National Cancer Institute and The Scripps Research Institute. Dr. Johnson's research uses mass spectrometry-based metabolomics to understand the role of metabolites in human health. Her primary research interest is to investigate the relationship between genetic and environmental influences (diet, hormones and microbiome) in colon cancer. She is also examining exposures during pregnancy.

      Dr. Liew is an environmental and perinatal epidemiologist and a research methodologist. A core focus of his work is understanding how exposures that occur during critical and vulnerable periods of development may shape disease risks and influence health outcomes throughout our life span. Dr. Liew is leading numerous studies with funding from the NIH to evaluate whether fetal exposures to endocrine disrupting compounds and/or neurotoxicants could harm fetal brain development leading to neurological disorders or impaired neuropsychological function in childhood and young adulthood. He is also interested in methodological research, especially the development of novel study designs and analytical techniques that could help us better address biases in observational studies or research using “real-world” data.

      • Mass Spectrometry
      • Exposome
      Dr. Pollitt’s research explores the human exposome through characterisation of environmental and biological samples using analytical and mass spectrometry (MS) techniques. Her group has developed various mass spectrometry (ICP-MS, LC-MS and GC-MS) to measure exposure to complex mixtures of trace elements and organic compounds. She has applied these exposure assessment methods in numerous in epidemiological studies.  Visit our lab website:

      Joshua Warren is an associate professor in the Department of Biostatistics at the Yale School of Public Health. He received his Ph.D. in statistics from North Carolina State University in 2011. Dr. Warren’s research focuses on statistical methods in public health with an emphasis on environmental health problems. Much of his work involves introducing spatial and spatiotemporal models in the Bayesian setting to learn more about associations between environmental exposures, such as air pollution, and various health outcomes including preterm birth, low birth weight, and congenital anomalies. He also has interest in developing and applying spatiotemporal models in collaborative settings such as epidemiology, geography, nutrition, and glaucoma research. His theoretical and methodological interests include multiple topics in spatial/spatiotemporal modeling and Bayesian nonparameterics.
  • Field and Data Research Team - LI

    • Postdoctoral Fellow

      My goal is to conduct policy-relevant research in the realms of exposure science, environmental epidemiology, and environmental justice. My research focuses on the environmental and human health impacts of oil and gas development and other emerging exposures on vulnerable populations, such as women, children, and rural communities.
    • Sheng is currently a second-year PhD student in Chemistry at Yale University in Prof. Krystal Pollitt's lab (School of Public Health) working on integrating the exposome in a multi-omics framework to understand the role of environmental chemicals on disease using GC-MS and LC-MS. At Yale Superfund Research Center, he will be working to quantify 1,4-dioxane and co-occurring chemical compounds in drinking water and blood by GC-MS. He is interested in anything mass spectrometry, e.g. MS-based proteomics, metabolomics, and exposomics.
    • Data Analyst; Biostatistician, School of Public Health

      Julie Plano is a biostatistician at the Center for Perinatal, Pediatric and Environmental Epidemiology at the Yale School of Public Health. Her primary research interests are assessing the effects of indoor and outdoor air pollution on at risk populations, and she currently focuses on providing statistical analysis and research support for epidemiological studies of environmental exposures and early childhood health outcomes.

      Over the past two decades, Livia (Lia) has worked closely with multiple principal investigators, co-investigators, collaborators, research staff, students, post-doctoral associates, and business office personnel supporting complex grant and contract management processes. She has expertise in reviewing, submitting, and completing IRB applications, modifications, and continuing reviews for projects involving human subjects research, for both the Internal Review Board (IRB) at Yale and external IRBs in several States in the US. Her primary goal is to offer the highest level of support for faculty in their research projects to further Yale's mission to preserve as well as to add to the body of human knowledge and expand our understanding of complicated scientific questions while seeking out resources and pathways to find their answers.
