Fifth year PhD student at NEU

I am a fifth 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. In our project, we studied how to use linear scoring functions to explain top-k tuples and rankings. We also made our techniques practical by integrating them with a existing DBMS to equip it with the functionality of query refinement.
