Research Interests

Cardiovascular disease is the leading cause of death in the United States, and two of its most pervasive risk factors are diabetes and the metabolic syndrome. The prevalence of obesity and diabetes has more than doubled in the US since 1980, and is continuing to climb. However, the tight link between insulin resistance and cardiovascular disease remains, in large part, unexplained. Thus a critical, unanswered question faces the diabetes field: what combination of factors causes the excess coronary disease in these patients? The overall goal of the research in the Haeusler lab is to understand the development of pro-atherogenic metabolic abnormalities in the natural history of diabetes and the metabolic syndrome.


Questions we aim to address:

How do abnormalities in hepatic lipid metabolism develop during insulin resistance?

How are these abnormalities related to defects in glucose metabolism?

Are bile acids signaling molecules that link insulin resistance to metabolic abnormalities?


Keywords that describe our work:

Metabolism, insulin action, bile acids, triglycerides, cholesterol, glucose, mouse models, lipoproteins, metabolic flux, physiology, pathophysiology, HDL, LDL, diabetes, atherosclerosis, cardiovascular disease, insulin resistance
