Bio
I am a research scientist at Facebook, working in Feed Data team.
I finished my Ph.D at College
of Computer and Information Science,
Northeastern University. My advisor is
Christo Wilson. I received my B.Eng. from
School of Information and Communication Engineering,
Beijing University of Posts and
Telecommunications.
My research interest is algorithmic auditing. In particular, I aim to improve fairness and transparency of blackbox algorithms of large-scale Web services.
Much of my work resolves around networked systems, data analytics and applied machine learning. I have leveraged the findings in my work to improve security,
fairness and algorithm performance in sharing economy, security and privacy, and online social networks.
