Alexander G Ramm, is  a professor of mathematics, the author of 699 research papers and 17 research monographs, and he has edited three books. He was a Fulbright research professor in Israel and a Mercator Professor in Ukraine. He also won the Khwarizmi international award. Ramm solved inverse scattering problems with non-over-determined data, the many-body wave scattering problem when the scatterers are small particles of an arbitrary shape, and he has used this theory to give a recipe for creating materials with a desired refraction coefficient. He proved symmetry results for PDE, including a solution to the Pompeiu problem and a proof of the Schiffer's conjecture.
