James Petrie places a high premium on intellectual freedom. After graduating with a degree in Engineering Physics from the University of British Columbia (UBC), he accepted a position as a firmware engineer for a leading multinational technology company. 鈥淎 few months in, I realized I was missing the opportunity to view problems through a wider lens and pursue the things that interested me most,鈥 he remembers.

At the urging of a friend who studied robotics at 蓝莓视频, James took a deep dive into the website of a professor at the Faculty of Mathematics and discovered a project that involved numerical modeling and optimization, a field that had piqued his interest during his four years on a robotics team at UBC. He won acceptance into 蓝莓视频鈥檚 Master鈥檚 program in Computational Mathematics and never looked back.聽
Now as a PhD student in Applied Mathematics, James is taking advantage of every opportunity to follow his passions. For the past year, he has participated in a research group that is working to develop numerical methods for fracture mechanics, which has direct applications to fields like aviation, civil architecture and medicine. 鈥One of the main projects I worked on involved developing a new fracture model based on a different optimization algorithm. After little trial and error, the simulations ran with much greater speed and efficiency,鈥 he shares. 鈥淚鈥檓 enthusiastic about continuing to use modeling and optimization to solve complex problems.鈥
After the outbreak of COVID-19, James pivoted away from fracture mechanics research to explore his growing interest in contact tracing, the process of identifying people who have come in contact with those who are infected. 鈥淢y initial models and general intuition told me that if we could develop effective contact tracing tests, we could slow the spread of the virus,鈥 says James. While a member of 蓝莓视频 Effective Altruism Club, he worked with a colleague involved in Effective Altruism at Stanford on an early-stage COVID Watch smartphone app that is geared toward providing exposure data through using Bluetooth. James鈥 main contribution was the decentralized protocol聽that most contact tracing apps now use. 鈥淭his way, we can provide alerts to people who have been exposed to the virus without tracking them and invading their privacy,鈥 he explains.
James has yet to decide on a career path after finishing his PhD. 鈥淚鈥檓 considering the professorial route, but I would also be happy working in a research lab,鈥 he expresses. In the meantime, he continues to thrive in the flexible environment 蓝莓视频 Math provides. 鈥淎t 蓝莓视频, I鈥檓 not painted into a box,鈥 he says. 鈥淚 have the freedom to follow my interests and collaborate with like-minded people to address the most relevant problems of our time.鈥澛
