• About ME

    Welcome to my website!

    My name is Tu Ni, and I was born in Hangzhou, China, 1994.


    I am a Ph.D. candidate in Operations Research & Analytics at National University of Singapore Business School. I'd like to develop mathematical modeling and algorithms with managerial insights in smart city operations problems for robust and flexible service design as well as dynamic and efficient online optimization. I am also interested in general artificial intelligence topics including machine learning/deep learning/reinforcement learning, natural language processing etc.


    I graduated at Hangzhou No.2 High School and after that, I spent my undergraduate life at Zhejiang University with a major of Mathematics. I hold a Master of Engineering degree at University of California, Berkeley with a concentration on Industrial Engineering & Operations Research. Moreover, I have worked in SF Express as a machine learning & operations research engineer for one year.
