Research Interests:  My lab works on human aortic aneurysms arising in the proximal aorta. I work mainly on human specimens to answer various questions pertaining to the pathological mechanisms of the disease in various patient populations. Our lab studies several patient populations, including patients born with a bicuspid aortic valve, the most common congenital cardiac malformation that places patients more at risk of developing an aneurysm in the proximal aorta. I am also interested in understanding the cellular mechanisms underlying sex differences in the clinical presentation of aortic aneurysms. Although men are more likely to develop aortic aneurysms, women with aortic aneurysms have a higher rate of mortality and morbidity when compared to men. Lastly, I am also interested in aneurysms due to genetic causes, such as Marfan syndrome. I am seeking answers to a wide variety of questions related to smooth muscle behavior in response to extracellular matrix and biomechanical cues.
