Hello!

I'm a graphics programmer with hands-on experience in non-photorealistic rendering, image processing, augmented reality, vector graphics, physics simulations, and graphic design. I was fortunate to receive a PhD from UWaterloo School of Computer Science in December 2020. My PhD research was about developing physics simulations that pack deformable shapes inside tight containers to automatically generate mosaic/packing art. I was awarded two best paper awards, a patent, and a scholarship. My advisors are two amazing teachers, Craig S. Kaplan and Paul Asente.
