I am a former student of Cornell's Computer Science department. I received my PhD in 2013 and am currently working at the D. E. Shaw group. Prior to coming to Cornell in 2007, I obtained my Bachelor of Mathematics majoring in Applied Mathematics and Computer Science at the University of Waterloo, in Waterloo, ON, Canada.
I have spent several terms interning at various companies as part of the University of Waterloo's cooperative education program. My first two work terms (Winter and Fall, 2004 - 8 months total) were spent as a Software Developer at Open Text Corporation. My position at Open Text primarily involved developing web-based interfaces for the search tools in Livelink - a software package for enterprise content management.
I also spent 12 months (Winter and Fall, 2006, and Summer, 2007) working as a developer at Side Effects Software, Inc. developing features in Houdini - a 3D animation package used in the film industry. This primarily involved development of a physics-based fluid simulator and other related tools.
Broadly speaking, my research interests lie in the areas of scientific computing and computer graphics. I am particularly interested in efficient algorithms for physics simulation and their application to areas such as physically based sound synthesis and surgical simulation. I am also interested in more general topics in scientific computing, including numerical linear algebra and numerical techniques for solving partial differential equations. My adviser is Doug James and I also work with David Bindel.
