Amir Sagiv
I am currently a Chu Assistant Professor in the Department of Applied Physics and Applied Mathematics at 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 am interested in differential equations, dynamical systems, optics and wave phenomena, uncertainty quantification, and mathematical analysis in general.
