"Do only what only you can do." - Edgar Dijkstra
I am very proud of all the students and postdocs that I have supervised over the years. I remember a saying that at some point of your academic career, it will not be about what you have accomplished, but what your students have!

Up to now, twelve students and postdocs I supervised have become professors themselves, at SFU, Carleton University, Jilin University, Nanjing University, National University of Defense Technology, Shandong University, Shenzhen University, and Zhejiang University, among others. Major high-tech companies where my past students are working or have worked at include Adobe, Amazon, Apple, Bytedance, Electronic Arts (EA), Google, Huawei, Meta (formerly Facebook), Microsoft, NVidia, and Snap.

According to the Mathematics Genealogy Project, the students below can trace back their "academic roots" as follows: Hao Zhang (Toronto), Eugene Fiume (Toronto), Alain Fournier (UT Texas), Zvi Kedem (Technion), Azaria Paz (Technion), Michael Rabin (Princeton), Alonzo Church (Princeton), Oswald Veblen (Chicago), E. H. Moore (Yale), H. A. Newton (Yale), Michel Chasles (Ecole Polytechnique), Simeon Poisson (Ecole Polytechnique), Joseph Lagrange (Pierre-Simon Laplace, too), Leonard Euler (Universitat Basel), Johann Bernoulli (Universitat Basel), Jacob Bernoulli (Universitat Basel), and Gottfried Leibniz (Universitat Altdorf, 1666).

Oh, by the way, my Erdös number is at most 3.
