Bio

I am joining Language Technologies Institute of Carnegie Mellon University in fall 2019 as a PhD student. I recieved my Master's degree in Computer Science from ADAPT Lab, Shanghai Jiao Tong University in 2019, under the supervision of Kenny Q. Zhu. I enjoyed collaborating with Jeffrey Bigham, Jiawei Han, Xiang Ren and Zhiting Hu among others on natural language processing topics and applications. Prior to that, I obtained Bachelor's degree of Computer Science from IEEE Honored Class, Shanghai Jiao Tong University in 2016, and earned Best Thesis Award in SJTU Bachelor's Thesis Defense (Top 1%).

Research

I work in natural language processing, deep learning, knowledge acquisition/reasoning and computational social science. I make NLP tasks feasible with less human effort by indirect or weak supervision and by building a two-way bridge between natural language text and structured knowledge, logic, relational data.
Some topics I am interested include text and code generation, contextualized and goal-oriented conversation, low-resource languages, reading comprehension, knowledge acquisition, reasoning and inference, grounded language learning, interpretable and structured models as well as NLP for social good.
My past research spans across natural language processing, deep learning, data mining and computational social science. More specifically: (a) cross-cultural, cross-lingual problems, (b) commonsense knowledge, (c) sequence labeling, (d) information extraction with weak or indirect supervision, (e) subword embedding, (f) controllable text generation, (g) social and urban computing.
