Irene E. Schauer, M.D., Ph.D

Associate Professor of Medicine

As a clinician scientist at the VA, my mission is to provide state-of-the-art Endocrinology care while also pursuing clinical research with the potential to impact patient care. My research addresses the role of insulin resistance and fatty acid elevation in increased cardiovascular risk with the ultimate goal of identifying novel therapeutic targets for cardiovascular risk management. I am studying the impact of insulin sensitizers with different mechanisms on cardiovascular function and mitochondrial function and oxidant generation. I have a particular interest in type 1 diabetes where cardiovascular disease risk has improved very little over the years and where insulin resistance is poorly understood and hence relatively difficult to target therapeutically. I am also interested in sex-based differences in the effect of diabetes on cardiovascular risk and function, particularly on the loss of premenopausal protection in women with diabetes. I bring a strong basic research background and clinical research skills to bear on these questions and plan to take these studies “to the bedside” in order to improve diabetes-associated cardiovascular disease risk and mortality.​​
