About Me

I am 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.

The goal of my research is to combine computer power and human effort to solve problems that cannot be solved by computers or humans alone. To achieve this goal, I study the design and analysis of systems with humans in the loop. I develop models and algorithms to acquire and utilize human-generated data for machine learning problems.

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. When I was in Taiwan, I focused on the study of Games with A Purpose (GWAP). In particular, I have developed several games, including PhotoSlap and KissKissBan, and started to get interested in studying social interactions behind these social computing systems.

Here is my CV and Google Scholar page. You can also reach me via [ch624 at cornell dot edu].
