Enkhmaa Byambaa, M.A.S., M.D., Ph.D.


Cardiovascular Research

Lipid and Lipoprotein Metabolism


Internal Medicine


  • Assistant Adjunct Professor


Clinical Interests

Dr. Byambaa's research interest is focused on risk factors for cardiovascular diseases (CVD), including metabolic syndrome, genetics and lipid and lipoprotein metabolism in various ethnic/racial groups. A major interest has been to identify factors that impact on Lipoprotein(a), Lp(a), a genetically regulated cardiovascular risk factor.

Her current research projects: to test the suitability of rhesus monkey as a model system for studies on Lp(a), to assess the roles of inflammation, endocrine dysregulation, HIV disease activity and antiretroviral therapy in modulating Lp(a) levels and associated atherogenic properties, and to identify genetic determinants of Lp(a) levels in humans.
