I'm currently a postdoctoral researcher at MIT, hosted by David Jerison, as part of the Simons collaboration on localization of waves.

Previously, I held a postdoc position at IAS (Princeton) from 2020 to 2022, hosted by Peter Sarnak. I received my Ph.D. from the Technion in 2020, where I had the pleasure of being advised by Ram Band.

My research lies within mathematical physics, and intersects with various mathematical disciplines, including Spectral Geometry, Graph Theory, Morse Theory, Real Algebraic Geometry, Fourier Analysis, Dynamics, and Number Theory.

Here are some of my recent works:


A detailed list of publications is found below, as well as nice pictures from these works and other projects.

This gif shows the evolution of a wave function on a quantum graph.
In this plot we see  |f(x,t)|^2  (the probability density) changing in time according to Schrödinger's equation, starting from a Gaussian of positive velocity.


How a continuous periodic change of edge lengths can "flip" an eigenfunction.

Left:  closed path in the parameter space -  possible edge lengths (L1,L2,L3) for which the star graph has eigenvalue equal to 1.

Right: The corresponding eigenfunction of eigenvalue 1, changing continuously with the edge lengths.
