Dr. Chen received his Ph.D. in Environmental Science and Engineering in 2016 from Nanjing University in China. During 2014-2015, he served as a Visiting Scholar at the Columbia University Mailman School of Public Health. Prior to joining the Yale School of Public Health faculty in July 2019, he was an Alexander von Humboldt Postdoc Fellow at Helmholtz Zentrum München-German Center for Environmental Health.Dr. Chen’s research focuses on the intersection of climate change, air pollution, and human health. His work involves applying multidisciplinary approaches in climate and air pollution sciences, exposure assessment, and environmental epidemiology to investigate how climate change may impact human health. Much of this work has been done in China, Europe, and the U.S.

Olivia N. Kachingwe, PhD, is an Assistant Professor of Public Health in the Department of Social and Behavioral Sciences at Yale School of Public Health. Her research focuses on understanding how healthcare providers, peers, family members (particularly fathers), and technology can better support the sexual and reproductive health of Black youth and young adults, with an emphasis on health disparities rooted in systemic racism and discrimination against LGBTQ+ communities. A central component of Dr. Kachingwe’s research is strong partnerships with community-based organizations and providers. She has expertise in qualitative methods and community-engaged research. Dr. Kachingwe received her Ph.D. from the University of Maryland in Behavioral and Community Health and completed a postdoctoral fellowship in Maternal and Child Health at Johns Hopkins Bloomberg School of Public Health in the Department of Population, Family and Reproductive Health. Dr. Kachingwe’s most recent projects include (1) a qualitative exploration of parent-child sexual health communication among Black LGBTQ+ young adults and (2) the evaluation of an evidence-based parenting intervention implemented among Black fathers and fathers on probation, parole, and supervised release.

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.
