I am a fourth year PhD student at Northeastern University. I am glad to be a member of the Data Lab and advised by Prof. Mirek Riedewald.
My current research interest focuses on explanations and fairness in databases, especially in rankings. For example, our recent project proposes why-not-yet problems by asking why-not questions in the context of top-k rankings and consider them satisfiability or optimization problems.
