Assistant Professor,
Industrial Systems Engineering & Management,
National University of Singapore.
Hi! I am an assistant professor at the Department of Industrial Systems Engineering & Management, the National University of Singapore. I received my PhD in Operations Research from the Operations Research Center, Massachusetts Institute of Technology, supervised by Prof David Simchi-Levi. More about me in my CV.
My research interests are online learning and resource allocation, which lie in the intersection of Operations Research (OR) and Machine Learning (ML). See Selected Works below, and Research Interest.
Post-doc position on OR and/or ML available: Please feel free to contact me for more information!
