I'm an undergraduate student at McGill University studying physics and computer science, along with a dash of mathematics (some would say more like a heaping scoop).
My current research interests include
- probabilistic analysis, probability theory
- random discrete structures: branching processes, random graphs
- reinforcement learning theory
- quantum information theory: entanglement and negative entropy
Over my time at McGill, I have the pleasure of working with great people from several organizations such as the Society of Undergraduate Mathematics Students, McGill NeuroTech and the McGill Classical Music Club.
In winter 2021, I will be the official botanist of a brand new course, SUMS 707: Basic Reinforcement Learning, taught by Viet and Gabriela. We will feature PDEs propaganda by Shereen as well as Markov chain and random trees indoctrination by myself. Sign up!
When I'm not watching lectures or scratching my head at QFT assignments, you can find me reading Dostoevsky, creating my next oddly specific Spotify playlist or playing piano and cursing Rachmaninov's handspan.

- Donut Electrodynamics, built in November 2020 with Diego, Shereen, Maia and Gabriela. Simulating electrodynamics on a flat torus. Won 1st place at the McGill Physics Hackathon!
- Random Trees, built in summer 2020 with Diego Lopez. Animating the free tree structures of randomly generated Galton-Watson trees of various offspring distributions.
- Fractal Graphics, building in progress with Diego Lopez. 3D mirror fractal rendered using a recusive ray tracing engine coded from scratch.
- MILO: the brain-controlled wheelchair, built in winter 2019 with McGill NeuroTechX. "Students from different backgrounds — including biology, computer science, hardware engineering, data collection, and machine learning — got together on their free-time to start a project to challenge themselves and improve the world around them. By gathering EEG bio-signals from the brain, they were able to process the data in order to direct the wheelchair forward, left, right, and stop. Over the course of the development, the students were able to create a wheelchair without using motor controls – just the control of the user’s mind – further improved with impressive semi-autonomous enhancements."
