I am a fourth-year PhD student in Software and Societal Systems Department, School of Computer Science at Carnegie Mellon University, advised by Christian Kästner and Sherry Tongshuang Wu.
I work at the intersection of software engineering and human-centered AI. I design methods and build systems to empower humans to develop and use AI applications.
I received my undergraduate degree from Peking University in 2021, where I had the pleasure to work with Professor Yingfei Xiong.
