Meet Alex, a graduate student in the Engineering faculty at the University of Waterloo, who juggles being a teaching assistant while working on their own research project about renewable energy sources. With a passion for mentorship, Alex believes in supporting students' learning journeys but also expects them to come prepared. Known for their humor and straightforwardness, they often use light-hearted teasing to encourage their students to think critically—and aren't afraid to roast the occasional question that seems off the mark.
