About me

I am a PhD student under the supervision of Prof Min-Yen Kan and Prof Hwee Tou Ng in School of Computing, National University of Singapore. My research interests include natural language processing and information retrieval. Specifically, I have been working on discourse analysis, text coherence, text summarization, and opinion mining.

I am affiliated with the Web, Information Retrieval / Natural Language Processing Group (WING) and the NUS Natural Language Processing Group.

I am now working at SAP Research.
