Education/Credentials
  • B.S.: Indiana University
  • Ph.D.: Medical College of Pennsylvania (now Drexel University)
  • Post doctoral fellowship: University of Illinois

Research/Clinical Interests

The mission of my laboratory is to determine the molecular basis underlying the protective effect of high density lipoproteins (HDL) against inflammation and atherosclerosis. We use a wide range of techniques spanning biophysical chemistry, molecular biology, and cell biology to understand: 1) the structural organization of the major HDL apolipoproteins and their transitions in response to lipid, 2) the molecular details of HDL interactions with cell surface receptors and transporters, 3) the protein and lipid compositions of HDL subspecies and their plasma distribution in the settings of cardiovascular disease, obesity and diabetes, and 4) the specific functions of the many HDL proteins and how they interact on the particle.
