# Simin Liu

Simin Liu (Chinese: 劉思敏) is an American physician-scientist and epidemiologist. He is recognized internationally for his leadership in the research of nutrition, genetics, epidemiology, and the environmental and biological determinants of complex diseases, particularly those related to cardiometabolic health in diverse populations. His research has pioneered novel concepts, uncovered critical mechanisms and risk factors, and developed research frameworks for diabetes and cardiovascular diseases. A hallmark of Liu's work is when his lab was among the first to define and quantify dietary glycemic load in humans, providing key insights into the functional role of dietary carbohydrates in the development of health outcomes. This novel nutritional concept has since become a cornerstone of clinical diabetes management, nutritional epidemiology, and dietary feeding trials in diverse populations worldwide.
As a leading epidemiologist and physician-scientist, Liu has cultivated a global collaborative community for evidence-based clinical and population health precision practices aimed at chronic disease prevention and control. Particularly in China and Brazil, he has helped colleagues develop numerous clinical and population studies on cardiometabolic outcomes spannig lifespans and even generations. These studies will prove to be unique and invaluable opportunities for aspiring public health investigators to address enduring questions in biological, clinical, and public health research. His leadership in global health has fostered a collaborative environment that drives innovation and cross-disciplinary research. Liu's collaborations extend both domestically and internationally, with the team engaging in research collaborations, teaching, and service activities across six of the Seven Continents.
A prolific scholar, Liu has an exceptional record of intellectual leadership. His research portfolio stands at over $20 million in extramural grant funding, 400+ peer-reviewed scholarly publications, and active participation in over 100 committees, advisory boards, and service events. As of November 2024, Liu has over 187,809 citations and an h-index of 155 on Google Scholar.

## Education

He earned his medical degree from Jinan University School of Medicine in China in 1991. He then earned his M.S. in epidemiology from the State University of New York at Albany in 1993. Liu went on to receive his master's degree in public health (MPH) and doctoral degrees (ScD) in both epidemiology and nutrition from Harvard University in 1998. Liu also completed a fellowship in public health and preventive medicine in the Epidemic Intelligence Service (EIS) program at the Centers for Disease Control and Prevention.

## Career

Liu is currently the Distinguished Professor and Chair of the Department of Epidemiology and Biostatistics at the Susan & Henry Samueli College of Health Sciences, University of California, Irvine. He also holds adjunct professorships at the Brown University School of Public Health and the Harvard T.H. Chan School of Public Health. Before joining the faculty at UC Irvine, he was a professor of epidemiology at Brown University School of Public Health and professor of medicine (endocrinology) at Brown University's Alpert Medical School. At Brown, he also served as the director of the Center for Global Cardiometabolic Health (CGCH) and has contributed to building several research and training programs in the global health space through a specialized blend of study in genomics, nutrition, and environmental science. Earlier in his career, Liu was the founding director of the UCLA Burroughs Wellcome Fund (BWF) Inter-school Program in Metabolic Diseases and the Center for Metabolic Disease Prevention, one of the few transdisciplinary doctoral programs in the country providing integrative training in population-based quantitative and biological sciences. From 2005 to 2013, he served as professor of epidemiology, medicine, and OBGYN at UCLA. From 1998 to 2005, Liu held positions as an instructor, assistant professor, and associate professor of medicine at Harvard Medical School and Brigham and Women's Hospital in Boston, as well as assistant and associate professor of epidemiology at the Harvard School of Public Health. He currently serves as an associate editor for The American Journal of Clinical Nutrition.

## Awards

He has served on several national and international committees and advisory board for the NIH, the CDC, the Chinese CDC, the Canadian Institutes of Health Research and Canadian Foundation for Innovation, the British Medical Research Councils(MRC), and the World Health Organization (WHO) addressing policy issues in both medicine and public health.
