About


I am a post-doctoral researcher at the Value from Data (Valda) team at École Normale Supérieure (ENS) Paris. My research focuses on theoretical aspects of database query optimization. On December 2020, I completed a PhD advised by Prof. Benny Kimelfeld at the Technion Data & Knowledge Laboratory.

Teaching


Combinatorics. This is the first class I taught, two years into my undergraduate studies, and my favorite "standard" class to teach. For me, the satisfaction in teaching comes from showing students how to think more effectively, and I enjoy the type of thinking that is at the core of this class. This class is taken by up to 350 students in normal semesters and 50 students in summer semesters. I received the Permanent Excellent Faculty Instructor Award for teaching this class in spring 2015 and winter 2016.

Competitive Programming. Workshop in Competitive Programming is a very unique class where students gain experience solving problems quickly in teams of three using short programs. The problems sometimes require ad-hoc solutions, sometimes use known paradigms (such as dynamic programming, divide and conquer, clever complete search, or a greedy approach), and sometimes incorporate known algorithms involving graphs, strings, maths, computational geometry, or any topic that can be considered computer science. Teamwork is also a big component of this class as each team of three students works together on one computer to try to solve up to 10 problems in 5 hours. To this aim, it is important to identify bottlenecks, prioritize the work, and communicate effectively with the other teammates. This is where students often get hands-on experience with topics they had only learned theoretically before. A competition at the end of the semester determines which team represents the Technion in the following Southwestern Europe Regional Contest (SWERC) of the International Collegiate Programming Contest (ACM-ICPC). I took this class myself as a student, and this was undoubtedly the best class of my degree! My team then competed in SWERC 2014 in Porto. As a TA, I pushed for expanding this class significantly to equip the students with the tools and tips we gained with experience. We added an hour of teaching prior to the weekly two-hour practices, and built lessons covering what we thought are the most useful parts in each of the aspects mentioned above.
