Runqiu Xu 徐润秋
I am a Visiting Student Researcher at the Speech, Audio, and Language Technologies (SALT) Lab at the University of Texas at Austin, working with Professor David Harwath. I recently completed my M.S. in Data Science at the University of Chicago. Before that, I earned a B.S. in Applied Mathematics and a B.A. in Finance at Wuhan University.
Research
I study how machines can reason with who is speaking, what is being said, and how multimodal interaction unfolds over time.
