Prof. Ralph A. DeFronzo, M.D - Type 2 Diabetes

Ralph A. DeFronzo, MD, is Professor of Medicine and Chief of the Diabetes Division at the University of Texas Health Science Center

and the Deputy Director of the Texas Diabetes Institute, San Antonio, Texas. Dr. DeFronzo is a graduate of Yale University (BS)

and Harvard Medical School (MD) and did his training in Internal Medicine at the Johns Hopkins Hospital.

He completed fellowships in endocrinology at the National Institutes of Health and Baltimore City Hospitals and in Nephrology

at the Hospital of the University of Pennsylvania. Subsequently, he joined the faculty at the Yale University School of Medicine

(1975-88) as an Assistant/Associate Professor.


From 1988 to present Dr. DeFronzo has been Professor of Medicine and Chief of the Diabetes Division at the University of Texas

Health Science Center at San Antonio. He also serves as the Deputy Director of the Texas Diabetes Institute.


His major interests focus on the pathogenesis and treatment of type 2 diabetes mellitus and the central role of insulin resistance

in the metabolic-cardiovascular cluster of disorders known collectively as the Insulin Resistance Syndrome.

Using the euglycemic insulin clamp technique in combination with radioisotope turnover methodology, limb catheterization,

indirect calorimetry, and muscle biopsy, Prof. DeFronzo has helped to define the biochemical and molecular disturbances

responsible for insulin resistance in type 2 diabetes mellitus.


For his work in this area, Dr. DeFronzo received the prestigious Lilly Award (1987) by the American Diabetes Association (ADA),

the Banting Lectureship (1988) by the Canadian Diabetes Association, the Novartis Award (2003) for outstanding clinical investigation

 world wide and many other national and international awards. He also is the recipient of the ADA’s Albert Renold Award (2002) for lifetime commitment to the training of young diabetes investigators.

 Dr. DeFronzo received the Banting Award from the ADA (2008) and the Claude Bernard Award from the EASD (2008).

These represent the highest scientific achievement awards given by the American and European Diabetes Associations, respectively.

In 2008 Dr. DeFronzo also received the Italian Diabetes Mentor Prize and the Philip Bondy Lecture at Yale.
Prof. DeFronzo is a distinguished clinician, teacher, and investigator who has been an invited speaker at major

national and international conferences on diabetes mellitus.

Pioneering Scientist Ralph DeFronzo Named 2017 Hamm Prize Laureate

Dr. DeFronzo spearheaded study of insulin resistance and diabetes drug metformin.

OKLAHOMA CITY – Imagine how different the lives of the one in three Oklahomans who have diabetes or prediabetes would be if this disease were cured, and the billions of dollars in annual health care costs saved.

Advancing progress toward that cure was the impetus for establishing the $250,000 Harold Hamm International Prize for Biomedical Research in Diabetes, the largest of its kind in the world, awarded by Harold Hamm Diabetes Center at the University of Oklahoma.

The Hamm Prize recognizes and encourages lasting advances in the field of diabetes research. It is awarded to an individual who

has either demonstrated lifelong contributions to the field or realized a singular advance, especially in leading toward a cure.

The 2017 recipient, Dr. Ralph DeFronzo, is directly responsible for many of the advances achieved in diabetes over the last 50 years.

He was a leader in developing the concept of insulin resistance, the defining characteristic of Type 2 diabetes,

resulting in novel ideas about the development and progression of diabetes.

DeFronzo led the U.S. development of metformin, the first-line medication for treatment of diabetes, and ushered it through FDA

approval in 1995. More recently, he discovered a new approach to diabetes treatment that targets glucose reabsorption in the kidneys.

This work led to the development and approval of other widely used drugs, including dapagliflozin, empagliflozin and canagliflozin.

DeFronzo is the author of 750 publications dating back to 1967. He currently serves as professor of medicine and chief of

diabetes in the Long School of Medicine at University of Texas Health San Antonio, where he has been on faculty since 1988.

“My hope in awarding this unprecedented international research prize is that we would ignite worldwide scientific interest and innovation to find a cure for diabetes in this generation,” said Harold Hamm, chairman and CEO of Continental Resources Inc., who provided the endowment to establish the prize, following his generous lead gift in 2007 for the establishment of Harold Hamm Diabetes Center.

Hamm’s endowment of the prize provides for its awarding in the future in perpetuity.

This endowment represents a unique private/public partnership using philanthropic dollars as a catalyst for desperately needed medical advances, which is especially beneficial in the current environment marked by declining federal funding for medical research.

“I am grateful to Harold Hamm for establishing this important prize and for the leadership and tenacity he has demonstrated

by taking action to address the diabetes health crisis,” said OU President David L. Boren. “The CDC has said that at current rates,

one in three people in America will develop Type 2 diabetes. This prize is another example of the forward momentum of

Harold Hamm Diabetes Center’s efforts to slow growing statistics like these.

 Dr. DeFronzo’s contributions to science directly benefit millions of Americans receiving treatment for diabetes.”

Prof. Dr. med. Dr. h.c. Peter Paul Nawroth

Peter Nawroth graduated in medicine from the University of Hamburg, trained in Tübingen, New York, Oklahoma and Heidelberg.

He is Professor of internal medicine and clinical chemistry at the medical faculty of the University Heidelberg, Germany. 

He is the division head of the joint Heidelberg-IDC-Translation Diabetes Program, Helmholtz Center Munich.


From 2007 – 2011 he was the Deputy Chair of the board of Directors, University Hospital Heidelberg and from 2011 – 2012 was

acting executive Medical Director. From 2011 – 2014 he was the Council Member of the European Association for the study of diabetes

and from 2013 – 2017 the Chair of the EASD study group “Reactive Metabolites in Diabetes”.

From 2005 – 2017 he was the Editor in Chief of ECED. In 2005 he was President of the annual meeting of the Thrombosis and Hemostasis Society of Germany and in 2007 President of the annual meeting of the German Diabetes Association. 

As of 2014 he has been the Speaker of the CRC 1118, Reactive metabolites as a cause of diabetic complications by the EASD.

In 2018 he was awarded the “Camillo Golgi Prize”.


Peter Nawroth’s principal research interest is the pathophysiology of diabetes and its associated complications, with the particular interest in nephropathy, neuropathy and macrovascular pathology and recently the mechanisms leading to diabetic pulmopathy.

His studies have focused on hyperglycemia dependent and independent generation of reactive metabolites and the impaired detoxification of reactive metabolites leading to organ dysfunction. He had done so by combining experimental models,

such as yeast, C. elegans, drosophila and mice, with proof of principle studies in patients with type 1 and type 2 diabetes.  


Peter Nawroth has published more than 200 scientific papers, review articles, book chapters and books.

He is active in publishing books not only for the science community but also for the general public.
