Yisong Yang is a Professor of Mathematics at Polytechnic School of Engineering, New York University and an Affiliated Professor of Mathematics at NYU Shanghai. He received his Ph.D. in Mathematics from the University of Massachusetts at Amherst in 1988. Prior to joining Polytechnic, he held academic appointments at the University of Minnesota (postdoctoral fellow), the University of New Mexico (assistant professor), Carnegie Mellon University (visiting assistant professor), and the Institute for Advanced Study (member). He was also a Professor of Mathematics at Yeshiva University.

Professor Yang’s research is in the fields of nonlinear partial differential equations and global analysis, with his main research interest focused on mathematical problems arising in theoretical physics. His contributions include construction of vortices in supersymmetric field theory, which are essential for the quark confinement mechanism; derivation of universal growth laws relating energy and topology for knots arising in a quantum field theory model in arbitrary dimensions; and existence theory for cosmic strings, which are responsible for matter accretion and galaxy formation in the early universe.
