Short Bio

I am Mo Yu, a Research Staff Member at AI Foundations Lab, IBM Research. My research is mainly focusing on information extraction, question answering, meta-learning and representations learning methods for NLP.

I received my PhD degree from Harbin Institute of Technology in Jan 2016. Prior to IBM, I was a visiting student at Johns Hopkins University during 2014-2015 working with Prof. Mark Dredze and Prof. Raman Arora. I was visiting Baidu NLP group during the year 2012-2013; and was visiting Microsoft Research Asia in the year 2008 and 2010. I have a broad range interests on Natural Language Processing and Machine Learning, such as semantic/syntactic analysis of texts and semi-supervised learning.
