About Me

I am an Assistant Professor in the Department of Computer Science & Engineering at Washington University in St. Louis. Previously, I was a Postdoctoral Associate at Cornell University working with Arpita Ghosh. In October 2015, I completed my Ph.D. in Computer Science at UCLA, where I am fortunate to be advised by Jenn Wortman Vaughan. I also spent three wonderful years from 2012 to 2015 visiting the EconCS Group at Harvard University, where I was hosted by Yiling Chen.

My research centers on the design and analysis of human-in-the-loop systems, using techniques drawn from the fields of machine learning, algorithmic economics, optimization, and online behavioral social science. I am interested in investigating the interactions between AI and humans, including studying how human behavior influences the design of machine learning algorithms and how the outcomes of machine learning impact human welfare.

I am from Taiwan. Before coming to the US for my Ph.D. study, I worked as a research assistant with Sheng-Wei Chen in the Institute of Information Science at Academia Sinica. Prior to that, I was a master student in Computer Science and Information Engineering at National Taiwan University, where I was advised by Jane Yung-jen Hsu.
