About Me

I am a PhD student at MIT working on computer vision and machine learning. I am interested in modeling the spatial and appearance transformations that we observe in realistic images, including 3D rotations of objects, complex lighting effects and even artistic effects. These models have a variety of applications including data augmentation and image synthesis.

Prior to graduate school, I worked for 3 years as a Software Engineer at Microsoft and Caradigm. I did my undergraduate studies at the University of Toronto in Engineering Science and Biomedical Engineering.
