The Elizabeth Selvin Lab examines the intersection of epidemiology, clinical policy and public health policy. One of our key goals is to use the findings of epidemiologic research to inform the screening, diagnosis and treatment of diabetes, cardiovascular disease and kidney disease. Much of our work looks at biomarkers and diagnostics related to diabetes and diabetes complications. Our findings — linking hemoglobin A1c (HbA1c) to diabetic complications and identifying the role of A1c in diabetes diagnosis — have influenced clinical practice guidelines.
