Lu Wang is an Assistant Professor of College of Computer and Information Science at Northeastern University since 2015. She is also affiliated with Northeastern NLP group and NULab for Texts, Maps, and Networks. She completed her Ph.D. in the Department of Computer Science at Cornell University, under supervision of Professor Claire Cardie in 2015. She earned her bachelor degrees in Machine Intelligence and Economics from Peking University in 2009.

Lu's research is focused on natural language processing, computational social science, and machine learning. More specifically, Lu works on algorithms for abstractive text summarization, language generation, argument mining, discourse analysis, and dialogue understanding, as well as novel applications that apply such techniques to computational social science and other interdisciplinary subjects.
