Student stories

Meet Jonathan

If you've been on a Faculty tour, or attended an event, you've probably met Jonathan. Not only is he welcoming guests to campus as a Math Ambassador, he also helps to train new tour guides. He's also leading the charge during Orientation, donning his pink tie and guiding a team through the welcome process.

A previous Finance Director for MathSoc, Jonathan is also involved with CS4U Day, an annual event held by the School of Computer Science, involving hundreds of high school students, teachers, and families who come to campus for an exciting day of speakers and hands-on activities.

Back home in Toronto, he volunteers with elderly, low-income Holocaust survivors, providing friendship and delivering meals. And in his spare time, you can find him at his computer, coding for his side projects.

Meet Mary

Mary has been an active member on the Waterloo campus with a number of volunteer activities. She has participated in MathSoc as an Office Manager, a Vice-President of Operations and Board Game Director and as an Math Orientation Leader with Orientation Week. In addition to volunteering, Mary keeps busy with field hockey and chess. While on co-op, she's worked as a Software Testing Engineering Co-op and Kernel Developer.
