Mathematician · AI Engineer · Founder
Hybrid profile spanning mathematics, AI, and entrepreneurship. Founder of three ventures connecting China–France–Ivy League education, U.S. AI R&D, and digital marketplaces. Currently in the inaugural cohort of the AI Management Master at Université Paris Dauphine-PSL.
About
A polymath chasing the intersection.
I started in mathematics, then spent four years exploring how mathematical thinking applies across education, media, cinema, and entrepreneurship. That exploration led me to AI — the meeting point of all of it.
In France, I went deep into philosophy, computer science, and digital art across three universities, before specializing in AI Management at Dauphine-PSL.
Today I write CUDA optimal-transport libraries on Saturdays, run a 300-student education company on weekdays, and field-research France's deeptech ecosystem with a friend from MVA on the side.
