Welcome to my website! Currently I am a research assistant professor in Musketeers Foundation Institute of Data Science and Department of Mathematics at the University of Hong Kong. Before that, I was a postdoc at Wisconsin Intitute for Discovery and lucky to work with Professor Stephen J. Wright. I received my PhD degree in Pennsylvania State University when I was fortunate to have Professor Uday V. Shanbhag as my supervisor and thesis advisor. My research interests are continuous, stochastic and robust optimization, with all types of applications including machine learning and data science. You may find more about me in my CV.

I am hiring postdocs and research assistants at University of Hong Kong. Outstanding candidates for Phd position are also welcome! Feel free to contact me (yxie21@hku.hk) if you are interested!
