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.

I have the expertise to mentor pre- and post-doctoral trainees in fundamental research and its application to cardiovascular, metabolic and amyloid diseases. Our laboratory is fully committed to attracting and retaining women and minorities in science, includes two T32-supported members who are URM, and is known for its supportive family-friendly atmosphere. Our trainees master quantitative biophysical, biochemical and structural biology techniques. They benefit from our local, national and international collaborations in cell, molecular and structural biology, including cutting-edge methods in mass spectrometry, computational biology, and clinical studies. These collaborations greatly enrich the training experience. All trainees are active in teaching at the undergraduate or graduate levels, and are actively obtaining funding for research and conference travel. Our past trainees have received multiple Young Investigator Awards from the Protein Society, Gordon conferences and other venues. All our trainees have multiple publications in peer-reviewed journals. All trainees have moved on to their own successful careers in life sciences, including industry, academia, consulting and venture capital.

My commitment to graduate students’ mentoring is evident from my service for nearly 20 years on the Students Admissions and Affairs Committee in the Department; 5 years on MD/PhD admissions committee at the Boston University School of Medicine; 15 years on Students Achievement Day committee. I also serve on the Admissions Committee for the Program in Biological Sciences (PiBS), an umbrella program in Graduate Medical Sciences at the School of Medicine. I have years of service as a facilitator of the NIH-mandated Responsible Conduct of Research training; on students’ ethics violations committees; on approximately 50 PhD thesis defense committees, and on PhD qualifying exams for over 50 students. For years, I have been teaching three graduate-level courses at the department and the school.
