  • Biosketch:
    Dr. Riddle`s clinical area of focus is in the treatment of diabetes with the aim of preventing or reducing its many disabling complications. "Diabetes, like most chronic illnesses, requires both standardized forms of treatment and individualization of care when standard methods fail," said Riddle, who heads OHSU`s Section of Diabetes. He is currently engaged in clinical trials called Diabetes Reduction Assessment with Ramipril and Rosiglitazone Medication (DREAM), and Action to Control Cardiovascular Outcomes in Diabetes (ACCORD).
