Founder and CEO at Deskfirst, where we build the world's easiest-to-use and fastest online collaboration workspace.

I obtained my PhD from the School of Computer Science at Tel Aviv University in 2020, where my advisor was Prof. Micha Sharir.
Here, you can find my dissertation: New Algorithms for Some Classical Problems in P. (Abstract, Acknowledgements)
I recieved my M.Sc. in Computer Science (magna cum laude) from Bar-Ilan University,
and my B.Sc. in Mathematics and Computer Science from Ben Gurion University.

During my PhD studies I have worked on some of the core problems in the field of algorithm design, which yielded the following results.
1) Improved algorithm and decision tree for the 3SUM problem (both were later further improved).
2) The first subquadratic-time algorithm for computing Dynamic Time Warping between two point-sequences on the line,
    breaking a 50 years old quadratic time barrier. This is the best-known algorithm for this problem to date.
3) The first strongly-polynomial subcubic-time algorithm for computing L Closest Pair of n points in Rn.
4) Proofs of the existence of various Diameter Spanners in directed graphs, and efficient algorithms to compute them.

Below, you can find the papers that include the results mentioned above, as well as additional papers.


Research interests: Design and Analysis of Algorithms, Computational Geometry.

During my M.Sc. studies in Bar-Ilan University I was a TA for the Automata and Formal Languages course, for which
I wrote the lesson plans that you can find in the link above. I hope that it can be helpful to students of relevant courses.
