Clinical Interests:
Diabetes mellitus, with particular interest in patients with unstable diabetes, insulin resistance, insulin allergy, poorly controlled type 2 diabetes, hypothyroidism, hyperthyroidism

Research Interests:
I am interested in the etiology and treatment of type 2 diabetes mellitus.  For many years, we have studied the role of the autonomic nervous system in the pathophysiology of type 2 siabetes in humans and a murine model.  We have also studied the mechanism of action of dietary therapy and a variety of pharmacological agents in the treatment of type 2 diabetes.

Dr. Richard Surwit of the Department of Psychiatry and Behavioral Sciences and I have developed a nutritionally-induced model of type 2 diabetes from the C57BL/6J mouse.  We have explored the dysregulation of the autonomic nervous system in the animal, leading to hyperglycemia, which is induced by a high fat diet.  We have examined in depth in this model the underlying genetic and biochemical abnormalities which lead to the development of obesity and type 2 diabetes.

We are conducting a variety of human studies.  NIH funded investigations of the interaction of depression and diabetes and, as part of a multicenter study, of the effect of very strict glucose control on cardiovascular outcome are in progress.  We continue to evaluate new treatment modalities for patients with type 2 diabetes, including new types of insulin, new classes or oral agents, and combinations of drugs.

I am frequently consulted by industry to evaluate new therapeutic modalities.  I most frequently peer review scientific articles concerning the treatment of type 2 diabetes.

Key words:  diabetes mellitus, stress, sulfonylureas, oral hypoglycemics, insulin, murine diabetes, diabetic diet
