Work spanning more than 45 years in internal medicine and biomedical research informs this physician’s role as an expert witness in matters involving metabolic disease, hematologic disorders, and related areas of clinical and laboratory science. A board-certified internist, he evaluates medical and scientific issues involving disease processes, treatment approaches, and clinical outcomes, and has more than 30 years of expert witness experience providing consultations, deposition testimony, and courtroom testimony in matters involving internal medicine and related biomedical disciplines. His academic preparation includes a Doctor of Medicine (M.D.) and a Master of Business Administration (M.B.A.).

His work integrates several areas of medical science and clinical investigation, particularly endocrine and metabolic disease such as diabetes mellitus and the clinical measurement of long-term glucose control. His research demonstrated that hemoglobin A1c can be used as a measure of long-term glucose control and documented that improved glucose management improves pregnancy outcomes in women with diabetes. His work also showed that patient self-monitored glucose values together with hemoglobin A1c measurements can serve as independent indicators used to assess metabolic control.

Another component of his expertise involves hematology, genetics, and pharmacologic research related to inherited blood disorders, including sickle cell disease and thalassemia, as well as investigational therapeutic approaches and drug development. His work has included sponsorship of multiple Investigational New Drug (IND) applications submitted to the U.S. Food and Drug Administration. In addition to clinical and research work, he has contributed to advances in medical diagnostics and biomedical technology, including development of an assay used to document alcohol consumption levels over time. He holds 15 U.S. patents and has authored more than 400 peer-reviewed publications along with 21 books and monographs, and has also been involved in telemedicine and technology applications within healthcare delivery systems.
