Amir Sagiv
I am currently an Instructor (starting a termed assistant professorship on July 2020) at the Department of Applied Physics and Applied Mathematics in Columbia University.
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.
