Hi! I'm an associate professor at the Department of Mathematics at the
Hebrew University of Jerusalem.
Before this I was a Sherman Fairchild Postdoctoral Scholar at the
Department of Mathematics in the
Division of Physics, Mathematics and Astronomy
I received my PhD from the
Department of Mathematics at the Hebrew University of Jerusalem.
My advisor was Prof. Yoram Last.
My MSc in chemistry was completed under the supervision of
Prof. David Avnir, at the
Department of Chemistry there.

- Fall Semester: Infinitesimal Calculus I. Lectures take place Sundays, 10:00--12:00, in the Auditorium in the Engineering building, Wednesdays, 10:00--12:00 in Feldman B, and Thursdays, 11:00--12:00 in the Kaplan hall.
- Spring Semester: Fourier Analysis. Lectures take place Sundays, 12:00--14:00, in room 110 of the Math Building.
- My office hours are Sundays, 12:00--13:00, or by appointment.
My areas of research are analysis and mathematical physics, which means that I am interested in analytical problems
motivated by physics. My work so far has concentrated around the area of spectral theory. In particular, I study
problems related to the spectral properties of random Schrödinger operators and random matrix ensembles, orthogonal
polynomials, transport phenomena in complex media and problems connected to spectral geometry.
