School of Electrical Engineering, Tel-Aviv University.
I have a Ph.D from the school of Electrical Engineering in Tel-Aviv University. I was privileged to be mentored by Prof. Emilia Fridman (https://www.eng.tau.ac.il/~emilia/).
Before that, I completed my B.Sc and M.Sc in Applied Mathematics at the School of Mathematical Sciences in Tel-Aviv University.
My work lies in Control Theory of PDEs, but I am also interested in general areas of mathematical analysis, such as: dynamical systems, functional analysis, operator theory, measure theory and numerical analysis.
My Ph.D. supervisor, Prof. Emilia Fridman, recently received the prestigious Kadar family award. Check out this video to see what Time-Delay Systems are all about!!!
