Gregory A. Nichols, PhD

Gregory Nichols, PhD, combines scientific training and policy vision with a hands-on understanding of the complexities of obtaining and analyzing health-utilization data. Dr. Nichols constructed Kaiser Permanente Northwest's Diabetes Registry in 1989 and has used it to conduct health services, economic, and epidemiologic research studies on patients before and after diabetes diagnosis. A recent focus of his work has been chronic kidney disease in type 2 diabetes (T2D), and the effect of delays in treatment intensification on complications of diabetes.

Other areas of interest include cardiovascular disease and the precursors to both diabetes and cardiovascular disease, commonly known as metabolic syndrome. Dr. Nichols recently led the creation of an 11-site diabetes registry that involves HMO research partners from around the United States. Other projects include studies of the association between hyperglycemia and cardiovascular disease, studies of diabetes incidence among patients with prediabetes, and a study assessing the proportion of patients with T2D who control cardiometabolic risk factors such as blood pressure, cholesterol level, and A1C, either alone or in combination, and their association with cardiovascular-disease hospitalization. Dr. Nichols participates in several multi-site studies that combine data from Kaiser Permanente Northwest and other Kaiser Permanente regions. Before becoming a CHR Investigator, Dr. Nichols served as a senior research associate at CHR, a rate analyst for Kaiser Permanente, and a financial analyst for the Northrop Corporation. He holds a PhD in public administration and policy from Portland State University and an MBA from Pepperdine University.
