Jiacheng Xu

Hi, I am Jiacheng Xu (徐嘉诚 in Chinese), a fourth-year Ph.D. student in the Department of Computer Science at the University of Texas at Austin. My adviser is Prof. Greg Durrett. My research interest focuses on Natural Language Processing and Machine Learning. More specifically, I work on text summarization and generation.

Before I came to UT Austin, I obtained my bachelor degree from Fudan University in 2017. From 2015 to 2017, I was a member of FudanNLP, advised by Prof. Xipeng Qiu. Check out the amazing Text Analysis, Understanding and Reasoning Group (TAUR) and the Machine Learning Group at UT Austin.
