    Dr. Dubrow has been heavily involved in the educational mission of Yale School of Public Health, as well as in research. Moved by what he sees as the greatest public health challenge in this century, Dr. Dubrow has committed himself to a new direction of education, training, and research on climate change and health. He serves as Faculty Director for a new Climate Change and Health Initiative at Yale School of Public Health, which aims to 1) create a cohort of leaders dedicated to addressing climate change and health; 2) establish an educational program on climate change and health for students across the University; 3) catalyze research on climate change and health utilizing Yale’s multidisciplinary expertise to generate innovative interventions and policy prescriptions; and 4) utilize public health science to support legislative, litigative, regulatory, executive, community, and other efforts to mitigate or adapt to climate change and to achieve climate justice. Dr. Dubrow serves on the Advisory Board of Cool Effect, a program that identifies some of the best carbon emission reduction projects in the world and makes it simple for supporters to donate.

    Dr. Dubrow has taught both Principles of Epidemiology I and Principles of Epidemiology II and was chosen by the Classes of 2002, 2007, and 2012 to be Teacher of the Year. He co-Chaired the Yale School of Public Health Accreditation Advisory Committee, which oversaw the School's self-study process leading up to its successful 7-year re-accreditation by the Council on Education for Public Health in 2014.

    Historically, Dr. Dubrow's research has focused on cancer, HIV, and their intersection. Most recently, his research has focused on two distinct areas: glioma (the main form of brain cancer) and HIV-related malignancies. He is currently developing a research and public health practice program in the area of climate change and health.

  • Yawei Zhang

    Section Chief and Associate Professor Tenure; Co-Assistant Cancer Center Director of Global Oncology, Yale Cancer Center; Chief, Section of Surgical Outcomes and Epidemiology, Department of Surgery

    Research Interests
    Air Pollution; Epidemiology; Lymphoma, Non-Hodgkin; Neoplasms; Pregnancy; Thyroid Neoplasms; Survivors; Genomics; Biostatistics

    Dr. Zhang's research focuses on cancer prevention and prognosis, early life exposures, and surgical outcomes. In particular, she has been pioneering the causes of increasing trends of thyroid cancer observed worldwide. As thyroid cancer is the fifth most common cancer among women in the United States, and factors that are responsible for this increasing trend are largely unknown. She is currently leading research activities in these areas as the PI of a population-based case-control study of thyroid cancer in Connecticut and a large nested case-control study of thyroid cancer in the Department of Defense Serum Repository (DoDSR) cohort. Dr. Zhang has been studying a wide array of environmental exposures, lifestyle factors and gene-environment interaction in the etiology and prognosis of non-Hodgkin lymphoma. She plays a major role in the International Lymphoma Epidemiology Consortium (InterLymph), and her research on hair dye use served as key evidence for IARC Monograph. She has also been studying environment factors and gene-environment interactions for multiple myeloma and cancers of the testes, pancreas, lung, liver, breast, and bladder. Currently, she is leading a large project developing novel approaches of monitoring and controlling major cancer risk factors in China.

    Dr. Zhang became interested in adverse pregnancy outcomes because the fetal origin hypothesis suggests that growth and developmental delays in utero may influence not only childhood mortality and morbidity but also the risk of diseases in adulthood including diabetes, cardiovascular diseases and cancer. Dr. Zhang’s birth cohort studies in Lanzhou and Taiyuan, China focus on investigating a wide range of environmental and lifestyle factors, genetic and epigenetic changes, gene-gene and gene-environment interactions, and risk of adverse birth outcomes and maternal complications.

    Dr. Zhang is bringing in her expertise to surgical outcome research in the Department of Surgery to develop a world-class frontier surgical outcome research program through cutting-edge evidence-based surgical outcome research projects, surgical outcome educational program, and international collaborations.
