About

I'm Xuanqi (Henry) Wei, a senior Mathematics & Statistics student at the University of Toronto with a minor in Computer Science. My work centers on uncertainty-aware statistical modeling and turning rigorous inference into actionable, real-world decisions.

My research at UofT's Department of Astronomy & Astrophysics applied Gaussian Mixture Models with MCMC sampling to determine stellar membership of the Ursa Minor Dwarf Galaxy, integrating orbital dynamics to identify genuine member stars in high-contamination outskirt regions.

In industry, I optimized warehouse logistics at WinTrust for Li-Ning by training a seq2seq Transformer on 300M+ orders, shortening pick-and-dispatch time by 12.4%. I also launched an internal startup building a low-cost ArcFace-based facial recognition system on Raspberry Pi, achieving over 99% accuracy across 20 stations.

Outside academics, I'm a CSIA Level II certified ski instructor at Mount St. Louis Moonstone and Blue Mountain Resort, a classical piano player, and an avid photographer who finds inspiration around the world.
