Research

Dr. Lessner’s work focuses on the vascular biology and biomechanics of atherosclerosis, with an emphasis on mechanical failure (plaque rupture) and intraplaque angiogenesis. Atherosclerotic plaque rupture is a leading cause of acute cardiovascular events such as heart attack and stroke. Evidence suggests that plaque rupture results from an adverse interaction between biomechanical and biological factors. Our research focuses on understanding the interplay between both these types of factors, in order to develop methods to reduce the incidence of plaque rupture.  On the biological side, we are particularly interested in intraplaque angiogenesis, or new blood vessel growth, as a destabilizing factor in plaque progression. We use transgenic mouse models and human endarterectomy specimens to examine the relationships between mechanical loading environment, matrix organization, and mechano-sensitive gene expression. On the biomechanics front, we study micromechanics of arterial tissue failure in plaque rupture and arterial dissection, and we aim to develop methods to identify patients at elevated risk of acute cardiovascular syndromes where material failure plays a major role. We use both experimental and computational approaches to understand artery wall failure mechanisms. I collaborate with faculty in Mechanical Engineering at UofSC, together with vascular surgeons at Greenville Hospital, Palmetto Health, and MUSC.
