I am an applied mathematician and computational scientist whose research focuses on cardiovascular engineering for rare and severe congenital heart disease. My work lies at the interface of engineering, applied mathematics and medicine, with an emphasis on modeling and simulation of how heart valves interact with blood flow. My research topics include modeling methods, simulation-guided design for cardiac surgery, and pathophysiology.

I am an Instructor in Cardiothoracic Surgery at Stanford University. I lead a research team supported by NIH and American Heart Association career development awards. I work with Michael Ma and in the Cardiovascular Biomechanics Computation Laboratory with Alison Marsden.

I completed my PhD in Mathematics in 2017 at the Courant Institute of Mathematical Sciences, New York University, working with Charles Peskin. My thesis concerned the mitral valve.
