I am currently working as a Senior Staff Engineer at Box, by way of acquisition of Progressly where I was the Principle Architect. Before that I was an Architect at Salesforce, by way of acquisition of RelateIQ. In a previous life, I was a researcher working with Professors Ron Fedkiw and Charbel Farhat at Stanford University, where my research interests included computational physics, numerical methods and computational fluid dynamics. I graduated with my Ph.D. in March 2012 from the Institute for Computational and Mathematical Engineering, under the guidance of Prof. Ron Fedkiw, with the dissertation entitled "Fully conservative leak-proof treatment of thin solid structures immersed in compressible fluids." I previously graduated from Worcester Polytechnic Institute with a B.S. in Computer Science and a minor in Mathematics.
