About Me

LocationWaterloo, ON
UniversityUniversity of Waterloo
ProgramMechanical Engineering

I'm a Mechanical Engineering student with a passion for innovation, robotics, and design. I've designed fully autonomous piano-playing robots to award-winning robots from scratch.

I work across mechanical, electrical, and software systems, with a specialisation in mechanism design and rapid prototyping. I love turning ideas into reality, whether through CAD modelling, mechanical simulation, or hands-on fabrication. Beyond engineering, I mentor students in STEM and enjoy camping, skiing, and other outdoor activities.

The harmonograph behind this page is inspired by a four-pendulum harmonograph that I saw at a science exhibition. That style of systematic yet evolving art spoke to me and inspired me to create a web version of that style of art. Feel free to play with the harmonograph and feel the same satisfaction that I had when I was a child.
