Portrait of Chi Wang

Chi Wang



I am a researcher in the Data Management, Exploration and Mining (DMX) group at Microsoft Research Redmond Lab. I completed my PhD from the Department of Computer Science, University of Illinois at Urbana-Champaign (UIUC). I had the pleasure to be advised by Professor Jiawei Han during the course of my PhD as a member of the Database and Information System (DAIS) Lab. I received my Bachelor’s degree in CS from Tsinghua University.

My research is centered around data science, an interplay between theories and systems. To help data scientists efficiently conquer big data and accomplish their tasks faster, I have developed sublinear solutions for a number of time-consuming tasks:

I am also studying a new application area for data science: SysML.

My past research in mining unstructured data such as text and graphs won me SIGKDD Data Science/Data Mining PhD Dissertation Award in 2015. A selection of my work in these areas can be found here.

I serve as a PC member in data mining, database, machine learning and NLP conferences.
