My research focuses on the foundations of data management. I am interested in studying real-life problems through the lens of well-defined and elegant mathematical formulations.
I am currently working on various aspects of graph query languages, and novel approaches for handling incomplete information.
I have completed my Ph.D. in August 2019 under the supervision of Prof. Benny Kimelfeld at the Computer Science Department, Technion. My Ph.D. dissertation deals with the complexity of queries for information extraction -- relational queries on data that is extracted from text. After my Ph.D., I was a postdoc at IRIF (Paris Diderot University) and in the Valda team at École Normale Supérieure Paris, hosted by Prof. Leonid Libkin, and funded also by DIM Math Innov and FSMP.
