Dr. Trevor Orchard, a physician epidemiologist, has served over 25 years as PI of the Pittsburgh Epidemiology of Diabetes Complications Study (EDC), which has been awarded MERIT status, and over 15 years as PI for the Pittsburgh DCCT/EDIC site. The EDC has published over 150 papers on type 1 diabetes complications. A major focus of the EDC Study has been renal complications, including the recent demonstration that all excess mortality is associated with micro (or worse) albuminuria. Dr. Orchard, an experienced clinical trialist, has received continual NIH research funding as a PI since 1980. He currently serves on the DCCT/EDIC Publications and Analysis Committee, and chairs three writing groups (SCOUT, Haptoglobin and Mortality) and performs similar roles for the Diabetes Prevention Program Outcomes Study (DPPOS). He has considerable experience in the epidemiology of mortality and diabetes complications, and in mortality/morbidity classification, having also performed such activities for the Community Cardiovascular Surveillance Project, the Allegheny County IDDM registry, the Diabetes Epidemiology Research International Studies, and the DPPOS. In addition, Dr. Orchard has trained 24 doctoral students, 33 master’s students and 8 post-doctoral fellows. He currently serves as PI on the CVD Epidemiology T32 training grant. Dr. Orchard also has taught the Cardiovascular Epidemiology Course for the last 15 years, and instructs clinical endocrine and cardiology fellows rotating through his Lipid Clinic. Finally for the last 5 years Dr Orchard has been assisting the development of diabetes care in Rwanda, through a programme called Life for a Child which has also provided MPH students with the opportunity to conduct their practicum in Rwanda.
