I am a 5th-year PhD candidate at the Language Technologies Institute (LTI)  of the School of Computer ScienceCarnegie Mellon University. My advisor is Prof. William W. Cohen of the Machine Learning Department (MLD). The best way to reach me is through email: ww@cmu.edu.

I have broad interests in machine learning approaches to language technologies, including statistical relational learning, information extraction, social media, and spoken language understanding. Previously, I received my M.S. in Computer Science from Columbia University. My advisors at Columbia were Prof. Kathy McKeown  and Prof. Julia Hirschberg. In Summer 2015, I was a research scientist intern at Yahoo! Labs NYC, working with Yashar Mehdad, Drago Radev, and Amanda Stent on low-rank approximation techniques for NLP. In Fall 2012 and Summer of 2012, I was a research intern at Microsoft Research, working with my mentors Dan Bohus, Ece Kamar, and Eric Horvitz on crowd-sourcing approaches to the acquisition of natural language corpora and machine learning approaches to open-world learning. From 2011 to 2012, I was the R. K. Mellon Presidential Fellow, working with Prof. Justine Cassell and Prof. Alan W. Black on sparse log-linear models for predicting impoliteness and positivity in peer tutoring sessions. In the Summer of 2010, I was a visiting researcher in  Prof. David Traum's natural language dialogue group at the  Institute for Creative Technology University of Southern California. From 2008 to 2009, I was a research assistant at Ambient Intelligent and Multimodal System Lab,  Chinese University of Hong Kong (CUHK) /Chinese Academy of Sciences (CAS). Prior to that, I worked with Dr. J.Y. Chen  on Semantic P2P Search and received my B.E. Summa Cum Laude in Computer Science from Shenzhen University in 2009. 

I publish regularly at top conferences and journals including ACL, EMNLP, NAACL, IJCAI, CIKM, COLING, SIGDIAL, IJCNLP, INTERSPEECH, ICASSP, ASRU, SLT, Machine Learning, and Computer Speech & Language. I review for journals including IEEE Transactions on Affective Computing (2010),  IEEE Signal Processing Letters (2011), IEEE Communications Letters  (2010, 2011) , Journal of the American Society for Information Science and Technology (JASIST)  (2012, 2014 x 2), Bioinformatics (2013), Journal of Medical Internet Research (2013, 2014), Artificial Intelligence (2014), and IEEE Transactions on Audio, Speech, and Language Processing (2013 x 3, 2014). I have organized or served as a PC member for many conferences and workshops including IJCAI 2015, NAACL 2015-2016, CIKM 2014-2015, ICASSP 2015-2016, and Interspeech 2015, and most recently, I served as the session chair for the data mining and machine learning session at CIKM 2013 and two text data mining sessions at CIKM 2014. I have received selective best paper awards (or honorable mentions) at conferences such as ASRU 2013, CIKM 2013, EMNLP 2015, and FLAIRS 2011. I was a recipient of the Richard King Mellon Presidential Fellowship in 2011, and was a Facebook Fellowship Finalist for 2014-2015 and 2015-2016. Besides academia, I do live in the real world. I have a National Badminton Coaching Certificate from State General Administration of Sports, China. I enjoy writing scientific articles that impact millions of people: my NLP/ML/speech microblog has 38,000+ followers and over 3,000,000 monthly views. In my spare time, I enjoy outdoor activities in state and national parks, as well as watching the Giallorossi games. Currently, my favorite player is the ninja Radja Nainggolan.
