Lei Sha (沙磊)

Ph.D Student, ICL@PKU

I work on question answering related techniques, including event extraction, textual inference, answer selection and answer generation.

I am very lucky to be co-advised by Zhifang Sui, Baobao Chang and Sujian Li.
I will attend Apple Inc. (Beijing) as NLP research Scientist in August, 2018.
