Biography

RESEARCH INTERESTS:

*Development of biomaterials to probe how structure, material properties and composition of the cell-biomaterial interface affect fundamental cellular processes

CURRENT FOCUS:

*Tissue engineering of small diameter blood vessels for bypass and intravascular pharmacology (e.g. stents)
*Engineering biomimetic systems to study restenosis and breast cancer
*Development of targeted nano- and micro-particle contrast agents for multi-modal (magnetic resonance, ultrasound, and optical) detection of atherosclerotic and vulnerable plaque

Cardiovascular disease is the leading cause of death in the United States. While there have been tremendous advances in the development of procedures to remove blockages in blood vessels (e.g. angioplasty, bypass surgery, and stent implantation), unfortunately a large number of these cases result in reformation of the blockage - a process known as restenosis. A major cause of restenosis is migration and growth of vascular smooth muscle cells (VSMCs). A major effort in the laboratory aims to understand how bioscaffold properties (e.g. structural, mechanical, and chemical) affect VSMC migration and growth. By systematically varying these bioscaffold properties, we hope to gain engineering design principles for the fabrication of not only devices to treat restenosis but also tissue-engineered blood vessels. Our laboratory fosters an interdisciplinary environment that integrates materials science and engineering, cell biology, microfabrication, and microscopy
