Amir Sagiv

I am a Term Assistant Professor at the Department of Applied Physics and Applied Mathematics in Columbia University, working under the mentorship of Michael Weinstein.

Before that, I was an Applied Mathematics Ph.D. student in Tel Aviv University's School of Mathematical Sciences, under the supervision of Gadi Fibich and Adi Ditkowski. I obtained my M.Sc. in Mathematics at Tel Aviv University, and my B.Sc. in Mathematics and Physics at the Hebrew University of Jerusalem.

I am interested in differential equations, dynamical systems, optics and wave phenomena, uncertainty quantification, and mathematical analysis in general.

See my CV here.
