Principal Investigator, Rodica Pop-Busui, MD, PhD
Dr. Rodica Pop-Busui is a prominent diabetologist at Michigan Medicine in Ann Arbor, and a nationally and internationally recognized leader in the field of diabetes as a result of her extensive clinical, research, teaching, and service activities. She has received awards from the Fulbright Foundation, the American Diabetes Association, and the University of Michigan. Since 2013, Dr. Pop-Busui has been an elected member of the Clinical Practice Committee of the American Diabetes Association (ADA), the world’s leading organization dedicated to preventing and curing diabetes. Dr. Pop-Busui also served as a member of the Complications Study Section of the Juvenile Diabetes Research Foundation (JDRF), a member of the study section of the American Heart Association, and a member of the National Institutes of Health NIH ZDK1 GRB-J J3 and NIH ZDK1GRB-S (O2) Study Sections.
Due to Dr. Pop-Busui's scholarship efforts, she is internationally recognized as an expert in the field of diabetes complications, especially diabetic neuropathies. A particular focus of her research interest and efforts involve diabetic peripheral and cardiovascular autonomic neuropathy. She has received funding for her research from the National Heart, Lung, and Blood Institute (NHLBI), the National Institute of Diabetes and Digestive & Kidney Diseases (NIDDK), the JDRF and the ADA. In addition, Dr. Pop-Busui has been privileged to contribute her research efforts to some of the most important national diabetes clinical studies to date, which have advanced the understanding of diabetes, informed changes in its treatment, and impacted the standard of care, thereby improving the lives of people affected by diabetes
As an investigator and site Principal Investigator of the NHLBI-funded Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial, Dr. Pop-Busui leads a team of ACCORD investigators from the United States and Canada in exploring the role of cardiac autonomic neuropathy on cardiovascular mortality in the study participants, and the effects of interventions on neuropathy risks in this cohort. As an investigator of the NIDDK-funded Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC), Dr. Pop-Busui took the lead in studies evaluating the natural history and the impact of metabolic memory on cardiovascular autonomic neuropathy in this cohort, and the role of cardiovascular autonomic neuropathy in the development of left ventricular dysfunction in type 1 diabetes.
Most recently, Dr. Pop-Busui is the site Principal Investigator and member of the Steering Committee of the newly funded NIDDK trial "PERL: A Multicenter Clinical Trial of Allopurinol to Prevent GFR Loss in Type 1 Diabetes" and site Principal Investigator in the NIDDK-funded trial "Glycemia Reduction Approaches for Diabetes: A Comparative Effectiveness Study (GRADE)." Â In addition, as a member of the American Diabetes Association Clinical Practice Committee, Dr. Pop-Busui has made major contributions to the Standards of Clinical Care in Diabetes in 2013 and 2014, and advocated for implementing the optimal care for diabetes and its complications, based on most rigorous scientific evidence, with the ultimate goal to improve the life of all people affected by diabetes.
Dr. Pop-Busui has devoted her life and career to the treatment and understanding of diabetes and its devastating complications, a commitment forged when she was a medical school resident and saw in her rotations the suffering of people with diabetes. Dr. Pop-Busui lives in Ann Arbor with her husband.

Cathy Martin, MS, APRN, BC-ADM, CDE
Cathy Martin has spent her entire professional career within the diabetes programs at the University of Michigan. She earned both her Bachelor of Science in Nursing and Master of Science degree at the University of Michigan. She is the 1995 recipient of the R. Faye McCain Memorial Award for Leadership and Academic Excellence in Medical-Surgical Nursing, and the 2013 winner of the Diabetes Champion Award from the Michigan chapter of the American Diabetes Association, in recognition of her outstanding contributions to diabetes education, advocacy, and research. Since 1987, she has been involved in a variety of clinical trials to advance the understanding of diabetes and to improve its treatment. Martin contributed to the landmark “Diabetes Control and Complications Trial” (DCCT), which demonstrated the benefits of aggressively controlling blood sugar levels in people with type 1 diabetes, as well as on the follow-up to that study, called “Epidemiology of Diabetes Interventions and Complications Study” (EDIC). She is currently study coordinator for the Glycemia Reduction Approaches in Type 2 Diabetes, A Comparative Effectiveness Study (GRADE). She has collaborated on nearly 50 publications and has been a sought-after speaker on diabetes topics for national organizations across the country. Given her long association with U of M, it should be no surprise that she is a fan of Michigan football and attends most home games. She enjoys golfing and biking in her spare time, and always has some home improvement project going on (ask her about the deck!).
Andrea Waltje, RN, MS
Andrea Waltje, RN, MS, brings her prior research experience to the team, having coordinated research projects on diabetes, tobacco cessation, and sun protection at the University of Michigan.
