I am now an assistant professor at Department of CSE with a joint appointment at Math Department at HKUST, and an associate director of HKUST-WeBank Joint Lab. I was an assistant professor at Lane Department of CSEE at WVU (2015-2016); a post-doc researcher at UIUC (2013-2015), a post-doc researcher at HKUST and visiting researcher at Huawei Noah's Ark Lab, Hong Kong (2012-2013); an associate researcher at Microsoft Research Asia (2010-2012); a staff researcher at IBM Research-China (2009-2010). I received my B.E. and PhD degree from Tsinghua University, China, in July 2003 and January 2009. I also worked as interns at Google in 2007-2008 and at IBM Research-China in 2006-2007.I am now a visiting academic scholar at Amazon Search Science and AI team (Jan. 2022 - present).

Recent Research Topics (Publications and KnowComp Group Code):My research goal is to use machines to understand human languages and eventually facilitate natural human language interaction and communication. Our current approach is to extract useful knowledge from existing resources to construct knowledge graphs and use knowledge graphs to do reasoning and inference for understanding. When meeting downstream applications, we also need to care about privacy, security, and fairness issues to build trustworthy real-world systems.
- Knowledge graph construction and information extraction.
- ProBase: a concept knowledge graph extracted from billions of Web pages (latest version).
- ASER: an eventuality knowledge graph of activities, states, events, and their relations.
- TransOMCS: population of a commonsense knowledge base in the format of OMCS transferred from linguistic patterns in ASER.
- DISCOS: population of ATOMIC if-then inferential commonsense knowledge base with the discourse relations in ASER.
- Natural language understanding and grounding to knowledge graphs.
- Selectional preference and conceptualization with large-scale knowledge bases.
- Entity linking, typing, semantic parsing, and discourse analysis.
- Machine learning, inference, and reasoning with world knowledge (A survey about text categorization).
- Learning with flat knowledge feature representation and domain adaptation.
- Learning problems with structural representation and new kinds of supervision signals.
- Privacy, security, and fairness issues in machine learning models.
