The Faculty of Mathematics recognizes three graduate students for their outstanding research papers. Sam Harris from Pure Mathematics and Ahmad Abdi from Combinatorics and Optimization each receive the 2018 Huawei prize, while Michael Cormier from the David R. Cheriton School of Computer Science wins the Murray Martin prize. The three PhD award winners include:

When an election is held we often employ a peculiar kind of logic. As we mull over the candidates we may have a top choice, but if we think our preferred candidate isn’t going to win we might vote for our second choice. Or maybe we cast a ballot for our second choice because we want to make sure that a frontrunner who doesn’t represent our view loses.

Researchers have developed a new way to improve our knowledge of the Big Bang by measuring radiation from its afterglow, called the cosmic microwave background radiation. The new results predict the maximum bandwidth of the universe, which is the maximum speed at which any change can occur in the universe.
The cosmic microwave background (CMB) is a reverberation or afterglow left from when the universe was about 300,000 years old. It was first discovered in 1964 as a ubiquitous faint noise in radio antennas.

At 14, Mubina Chunari hadn’t chosen her dream job, but she knew she loved math. At the time, she couldn’t figure out how to make a living by loving math and it was holding her back. The only adults she’d met with careers in math were either university professors or her own teachers. Although teaching interested her, she wanted a career outside of academics that would fit more into her personal growth goals.

Waterloo graduate student David Qian, under the guidance of the Faculty of Mathematics’ Ricardo Fukasawa and Jochen Koenemann, introduced optimization techniques based on integer and dynamic programming to surgeons at SickKids hospital. By applying mathematical optimization algorithms, Qian and team advised doctors on the best surgical cut points to minimize the volume-difference between the surgically modified skull, and an ideal skull.
