Zekai Wu

I am Zekai Wu (吴泽楷), a second year Ph.D. student at the Department of Computing at The Hong Kong Polytechnic University. My advisor is Professor Bo Li.

Prior to this, I received my B.Eng. degree in Computer Science and Technology and B.Econ. degree in Economics from the Harbin Institute of Technology, Shenzhen. I was fortunate to complete my B.Eng. thesis under the supervision of Professor Shengxin Liu.

I have a broad interest in theoretical computer science, microeconomics, and pure mathematics. Currently, I focus on Algorithmic Game Theory and Fair Division problems specifically.

Fun Facts

I love skiing. Exploring more breathtaking snow-covered mountains has been a constant source of motivation for me. During my recent visit to Whistler, Canada, I felt increasingly comfortable with blue runs, as well as on mild mogul terrain and sparse trees. In the future, I hope I can visit more mountains in China, Japan, New Zealand and Europe. I'm also looking for skiing partners. I'll keep a list of ski resorts I've already visited here.

I was fascinated by coding. A few projects can be found on my Github. I also enjoyed competitive programming, although I spent much less time on it after shifting my focus to theoretical research.

My nickname "CandyOre" originates from Minecraft. Sometime around 2015, I was messing around my in-game house with TofuCraft and OreGemPlant mods, when I suddenly wanted an original username. Pondering at ore blocks and sugar cane, I decided to be CandyOre.

The name can be interpreted as a playful reference to the origin of candy — sugar cane. It may also represent a personality that is sweet on the inside and tough on the outside, where one has to dig and refine them to uncover the sweetness.

I also made the avatar myself using Blender.

TODO. I may write more about me in the future xD.
