David G. Marrero, PhD, is the director of the UA Center for Border Health at the University of Arizona Health Sciences. The Center for Border Health works to develop programs and strategies to improve health and wellbeing along the U.S.-Mexico border and across the greater Southwest.

Dr. Marrero, whose research has focused on medication adherence, community health programs, early diabetes intervention and translational medicine, also is professor of public health at the UA Mel and Enid Zuckerman College of Public Health, Department of Health Promotion Sciences, and professor in the UA College of Medicine – Tucson, Department of Medicine, Division of Endocrinology.

The Center will focus on building extensive collaborative efforts to affect treatment of type 2 diabetes in border populations. Working with the Arizona Area Health Education Centers (AzAHEC) and other UAHS centers, the Center for Border Health is establishing Regional Arizona Centers of Excellence in Clinical Research (or RACER sites) in Yuma and Nogales to provide mental health services for individuals with diabetes and to develop culturally appropriate and relevant training programs. 

Dr. Marrero joins the UA Health Sciences after 20 years at Indiana University, where he served as director of its Diabetes Translational Research Center and the J.O. Ritchey Professor of Medicine. He was instrumental in the development of a Diabetes Prevention Program and the TRIAD study, which evaluated strategies to improve diabetes care delivery in managed-care settings, among many other achievements.

Twice awarded the Allene Von Son Award for Diabetes Patient Education Tools by the American Association of Diabetes Educators, Dr. Marrero has been nominated to Who’s Who in Medicine and Health Care in 2000, served as associate editor for Diabetes Care (1997-2002) and is the associate editor for Diabetes Forecast. He was selected for an Alumni of the Year award from the University of California, Irvine in 2006 and Outstanding Educator in Diabetes in 2008 by the American Diabetes Association. In 2016, he served as the president for health care and education of the American Diabetes Association. His research interests also include strategies for promoting diabetes prevention, improving diabetes care practices used by primary care providers and the use of technology to facilitate care and education. His clinical interests include diabetes, obesity and coping.

Dr. Marrero received a bachelor’s degree (1974), master’s degree (1978) and doctorate (1982) in social ecology from the University of California, Irvine.

Lawrence J. Mandarino, PhD

Lawrence J. Mandarino, PhD, is the director of the UA Center for Disparities in Diabetes, Obesity and Metabolism at the University of Arizona Health Sciences. Dr. Mandarino also serves as chief of the Division of Endocrinology, Diabetes and Metabolism in the Department of Medicine at the UA College of Medicine – Tucson.

Prior to joining the UA, Dr. Mandarino served as director of the Center for Metabolic Biology and director of the Mayo/ASU Center for Metabolic and Vascular Biology at Mayo Clinic Arizona at Arizona State University. Dr. Mandarino spent more than 12 years at the University of Texas Health Science Center at San Antonio in the Departments of Medicine, Biochemistry and Physiology. He has held faculty appointments at the University of Pittsburgh and the University of California, San Diego, after performing a postdoctoral fellowship in endocrinology at the Mayo Clinic.

The UA Center for Disparities in Diabetes, Obesity and Metabolism serves as a nucleus for interdisciplinary research that forms the foundation for advanced, evidence-based clinical care. A major focus of the center are innovative approaches to delivery of care and prevention, serving a diverse population in one of the most high-risk yet underserved regions in the nation.

Dr. Mandarino’s research has been supported by the National Institutes of Health for more than 25 years. Currently, he is principal investigator on two studies with grant funding totaling more than $5 million. His research interests include the mechanisms of insulin resistance in skeletal muscle and liver and the mechanisms of fatty liver development. His research is aimed at providing new targets for treating insulin resistance syndrome – sometimes referred to as metabolic syndrome – which increases the risk of obesity, type 2 diabetes, cardiovascular disease and other cardiometabolic conditions, all areas of special concern in the Latino population. In 2009, he received the American Diabetes Association’s Cure Award, presented to a key researcher who is engaged in basic or clinical research focusing on the treatment, cure or prevention of diabetes and its complications.

An active supporter of the training of physician-scientists and biomedical researchers, he has mentored many post-doctoral and medical research fellows and graduate and undergraduate students. He has more than 140 articles published in peer-reviewed journals. He has been associate editor of Diabetes; a reviewer for Diabetes Care, Diabetologia, Journal of Clinical Endocrinology and Metabolism, Journal of Clinical Investigation, and Metabolism; and serves on the editorial board of the Journal of Proteome Research. His professional memberships include the American Association of Physical Anthropologists, American College of Sports Medicine, American Federation for Clinical Research, American Physiological Society and American Diabetes Association.

Dr. Mandarino earned his bachelor’s, master’s and doctoral degrees at ASU. After earning his doctorate in 1978, he joined the Mayo Clinic in Rochester, Minn., where he was a senior research fellow and also an assistant professor at Mayo Medical School. He then joined the faculty of the University of California, San Diego, in the Division of Endocrinology and Metabolism, and was core laboratory director of the General Clinical Research Center. From 1987 to 1992, he was assistant professor in the Departments of Ophthalmology and Physiology at the University of Pittsburgh School of Medicine. He then served as associate professor in the Departments of Medicine, Biochemistry and Physiology and as professor in the Department of Medicine, Division of Diabetes, at the University of Texas Health Science Center at San Antonio.

In 2005, he joined ASU as professor and chair of the Department of Kinesiology and founding director of the Center for Metabolic Biology, which brings together basic scientists and physician-investigators to understand the mechanisms involved in the development of insulin resistance, type 2 diabetes mellitus and cardiovascular disease. In 2010, ASU and Mayo Clinic in Scottsdale partnered to create the Mayo/ASU Center for Metabolic and Vascular Biology, to combat obesity, diabetes, cardiovascular disease, stroke and other related conditions, and Dr. Mandarino was appointed director.
