My Research Interests

I love physics, and earned a minor in physics as an undergraduate. Studying applied math has allowed me to stand on the border between math and physics -and I love it here because I basically have a passport between disciplines. It allows me to study multiple subjects and cross borders between not only math and physics, but also biology, chemistry, engineering, computer science – it’s fantastic!

My PhD advisor, Arnold Kim, and I are currently working on problems studying light propagation in biological tissues governed by the Radiative Transport Equation. We model backscattered light from layered tissue composed of a slab on a semi-infinite half space. Our current work utilizes the corrected diffusion approximation which applies a boundary layer solution to the standard diffusion approximation and has shown significant improvement in data close to the source. This means that I currently am able to combine my interests in math, physics, and biology for the purposes of our research.
