Biography

Our research focus is on protein folding, structure and stability. It includes the analysis of the energetic-structure-function relationship and folding pathways in proteins and peptides by circular dichroism spectroscopy, differential scanning calorimetry, fluorescence, x-ray crystallography, and site-directed mutagenesis.

Our on-going NIH-funded work is aimed at understanding the energetic and structural basis for the conformational plasticity of apolipoproteins. These are protein constituents of lipoproteins that mediate lipid transport and metabolism and are central in the pathogenesis of atherosclerosis, stroke, and certain forms of amyloidosis. Apolipoproteins are distinct in their structural adaptability to various lipoprotein particles and to plasma. We try to understand in molecular detail the energetic and structural basis for this adaptability.

A major focus of our research is on the molecular mechanisms of lipoprotein stabilization and fusion. In 2002 we revealed that lipoprotein stability is determined by kinetic barriers. Similar barriers may modulate in-vivo lipoprotein transformations. Our goal is to obtain key molecular determinants for these energy barriers.
