I am a PhD student in computer science, supervised by Prof. Noga Alon. My Master's degree was also completed in Tel Aviv University under the supervision of Noga Alon.

Research interests

The interplay between structure and algorithms in computer science, with a focus on sublinear algorithms for highly structured problems. Some topics on which I've been working recently:
  • Property testing in ordered structures, and related combinatorial questions.
  • Practical sublinear algorithms for sampling in real-world social networks.
  • Deep representation and synthesis of structured data.
  • Adversarial robustness of algorithms for massive data.
