I am a final year CS PhD student at Cornell University working on Natural Language Processing. My advisor is Prof. Claire Cardie. Before that, I did my undergraduate study at Shanghai Jiao Tong University.

Research

I am broadly interested in Natural Language Processing and Machine Learning methods that can be used to automatically learn the underlying knowledge in languages.

On the methodology side, I am intrigued by elegant models with end-to-end training, such as the capability of Deep Neural Networks to learn powerful representations without explicitly injecting human knowledge. I am also interested in structured prediction models that can handle complex output spaces since NLP problems usually have structured outputs.

On the application side, I am very interested in extracting and understanding knowledge behind languages, such as representation learning, information extraction, reading comprehension, etc.

Recently, my proposed thesis research focuses on learning deep representations for low-resource / zero-resource cross-lingual model transfer.

Experiences

05.2018 - 08.2018, Microsoft Research, Redmond, WA.
Research Intern with the Language and Information Technology team
Worked on zero-resource cross-lingual model transfer (pdf).

05.2017 - 08.2017, Facebook, Menlo Park, CA.
PhD Intern working with the Search NLP team
Worked on Aspect Extraction on review data. E.g. In review I like the food but the service is terrible., the system should extract food as a positive aspect while extracting service as a negative one.

05.2016 - 08.2016, IBM Research, San Jose, CA.
Research Intern with the Scalable NLP team
Worked on understanding the structure and semantics of tabular data in financial documents. Our paper was published on ICDAR 2017.

05.2015 - 08.2015, Google, Mountain View, CA.
PhD Intern with the Display Ads Predictive Targeting team
Implemented a new targeting model based on Slope One collaborative filtering to recommend keywords to Ads for better coverage using only keyword performance statistics.

05.2012 - 02.2013, Microsoft Research Asia, Beijing, China.
Full-time Intern working on Machine Translation with Dr. Dongdong Zhang and Dr. Ming Zhou Designed an all-in-one GUI Auto Trainer for the Machine Translation pipeline of MSRA. Participated in a real-time speech-to-speech machine translation task (News, Video)

Miscellaneous

I cook on a daily basis when I’m stuck in Ithaca where good Chinese food is scarce.

I do archery (mostly indoor Olympic-style recurve archery) in my spare time, and sometimes go skiing when weather permits.
