    Dr. Brian Leaderer is the Susan Dwight Bliss Professor of Epidemiology in the Department of Environmental Health Sciences at the Yale School of Public Health and he is Professor at the Yale School Forestry and Environmental Studies. He is the Co-Director of the Yale Center of Perinatal, Pediatric & Environmental Epidemiology (the Yale CPPEE, or the "Center"). 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 (totalling 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 of from this study resulted in another ongoing 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.

    Andrew Dewan is a genetic epidemiologist with a focus on extending and applying analytical methods to identify genetic susceptibility variants for complex traits. A key theme throughout his work is applying a strategy of delineating narrowly defined phenotypes and stratification by ancestry to reduce heterogeneity and increase statistical power. To better elucidate the genetic architecture of complex traits, his research extends analytical methods to identify genetic interactions as well as pleiotropy. He has applied these genetic mapping methods across a number of diverse phenotypes including asthma, obesity, leukemia, pediatric lung cancer, preeclampsia, preterm birth, and bacterial bloodstream infections. He has been the Principal Investigator of external grants to fund his research (5 NIH grants, including three R01s). He is the co-Director of the Yale Center for Perinatal, Pediatric and Environmental Epidemiology (CPPEE) which brings together diverse faculty with interests in the health of women and children through epidemiologic research investigating the impact of environmental, genetic and clinical factors on pregnancy, birth and childhood. He recently served a three-year term as a member of the Program Committee for the American Society of Human Genetics, the primary scientific organization for human geneticists worldwide. He has been able to incorporate my research interests through to my educational activities, teaching the course Genetic Concepts in Public Health, guest lecturing on genetic epidemiology and teaching at international courses for linkage and association analyses.
