  • Co-Director

    Susan Dwight Bliss Professor of Biostatistics; Affiliated Faculty, Yale Institute for Global Health; Director, Center for Methods in Implementation and Prevention Science (CMIPS); Director, Interdisciplinary Research Methods Core, Center for Interdisciplinary Research on AIDS; Assistant Cancer Center Director, Global Oncology, Yale Cancer Center

    Donna Spiegelman was appointed the Susan Dwight Bliss Professor of Biostatistics at the Yale School of Public Health in 2018. As one of the few people in the world with a joint doctorate in biostatistics and epidemiology, she can freely speak the languages of both disciplines and switch between these two professional cultures, playing the role of interlocutor for either. Her research is motivated by problems which arise in epidemiology and require biostatistical settlement. In particular, but by no means exclusively, she has focused on methods for study design and data analysis which reduce bias in estimation and inference due to measurement error or misclassification in the exposure variable. A particular current interest is risk-based monitoring of multi-center investigations to enhance quality and prevent fraud.She has extensive experience in troubleshooting and solving methodological issues that arise in longitudinal investigations, in clinical trials, and in large scale public health effectiveness evaluations. Before coming to Yale in 2018, Dr. Spiegelman played dynamic roles as professor, mentor, and expert statistician at the Harvard T.H. Chan School of Public Health for nearly 30 years. She was the recipient of the NIH Director’s Pioneer Award and recently the recipient of the Committee on the Advancement of Women Faculty Mentoring Award.

    Research Scientist in Public Health (Social and Behavioral Sciences)

    Dr. Amber Hromi-Fiedler is currently a Research Scientist in the Department of Social and Behavioral Sciences in the Yale School of Public Health. Dr. Hromi-Fiedler obtained her B.A. in Psychobiology from Wheaton College in Norton, Massachusetts, in 1994. In 2002, she obtained her M.P.H. from the University of Connecticut and in 2007 she obtained her Ph.D. from the same university. Dr. Hromi-Fiedler specializes in community nutrition with emphasis in maternal and child health (MCH) both domestically and internationally. Internationally, she participated in the implementation of an MCH project with Save the Children in Uganda. In Ghana, with funding from the NIH, she developed and taught an intensive course to build the capacity of local Ghanaian health professional by enhancing their knowledge and skill of analyzing nutritional data using a public domain software available through the Centers for Disease Control. In Ghana, she also collaborated in the training of nutrition staff and the development of nutrition education materials for Liberian refugee caretakers at Buduburam Refugee Camp. The nutrition education materials focused on child nutrition as well as food safety and are currently being used and distributed to caretakers to improve nutritional outcomes among Liberian refugee children. She also conducted a postdoctoral summer fellowship in Ghana examining dietary practices, food availability, and nutritional status among Liberian refugees and Ghanaians living in and around Buduburam Refugee Camp.  She continues to work in Ghana on infant and young child feeding projects.  Domestically, she has taken the lead on the adaptation of the U.S. Food Security Scale, a national instrument to measure food insecurity, among pregnant Latina women. Dr. Hromi-Fiedler implemented one of the first longitudinal studies in Hartford, CT, examining the association between food insecurity during pregnancy and infant outcomes among Latinas. Dr. Hromi-Fiedler has also conducted feasibility research to develop a community-based intervention to increase fruit and vegetable consumption among low-income pregnant Latinas.  Dr. Hromi-Fiedler has presented her work at national and international conferences. Dr. Hromi-Fiedler has authored or co-authored several research articles in the fields of interest.
