I am a (tenure-track) Assistant Professor at the KTH Royal Institute of Technology, in Stockholm, Sweden.
I am part of the Division of Theoretical Computer Science of the Computer Science Department.

Previously, I was a Postdoc in the Basic Algorithms Research Copenhagen (BARC) group at the IT University of Copenhagen, hosted by Prof. Thore Husfeldt. Before joining BARC, I was a Postdoc at Tel Aviv University, hosted by Prof. Guy Even.

I obtained my PhD in Computer Science from the University of Maryland.
I had the privilege of being advised by Prof. Samir Khuller.
I obtained my Master's degree from UMD under the supervision of Prof. Aravind Srinivasan.
I graduated from the University of Chicago, with a Bachelor of Science in Mathematics (Honors) and Computer Science.

Research Interests

I am interested in the broad area of Theoretical Computer Science and specifically in
  • Data Structures (e.g. dictionaries and Bloom filters)
  • Randomized and Approximation Algorithms (e.g. hashing, clustering)
  • Computational Geometry (e.g. Traveling Salesman Problem)
