**RESEARCH**

I work on problems at the interface of mathematics and medicine, focusing in particular on mathematical modeling, simulation, and analysis of cardiovascular dynamics. My models range from lumped parameter compartmental models to three-dimensional finite element models designed to elucidate underlying physiological and pathological biomarkers. I also develop post-processing tools for further data quantification. I enjoy collaborations with a variety of fields including biomedical engineering, cardiovascular medicine, and exercise science.
