Since 2019, I have been an assistant professor at the Stevens Institute of Technology. Previously, I was an associate professor at the Chinese Academy of Sciences and a faculty member and Ph.D. advisor at Tsinghua University. As a graduate student supervised by Hermann Ney from RWTH Aachen, I had fruitful visits to IBM in Watson and the NLP group in Microsoft Research (MSR) Redmond. My current research interests are in Machine Learning, with a focus on highly competitive machine translation systems. Lately, I have developed an interest in devising techniques that explore the underlying metric and geometric properties of machine translation systems. I am publishing in mainstream venues in computational linguistics and machine learning (e.g., AAAI, ICML, ACL). I am often leading teams that win first (or one of the first) position in machine translation competitions.
