Introduction

I am an research scientist who works in many fields of science and engineering. My research tends to be highly interdisplinary and to reside at the interfaces between traditional fields of study. When approaching problems, I strive to synergistically integrate ideas from science, engineering, applied mathematics, and computational science & engineering.

In my experience, a team effort is often required to make progress on interdisciplinary problems. I am fortunate to have many great collaborators from around the world. My most active collaborations are currently with several researchers at the Institute of High Performance Computing (a research institute under A*STAR) in Singapore. To keep the ideas flowing and cross-pollination of ideas frequent, I am always actively seeking out new people to work with and interesting problems to work on.

My current research projects focus on numerical analysis, material science, and scientific software development. I am also in beginning new projects in the areas of biophysics and high-performance scientific computing.
