Vasy's main area of research is in partial differential equations, which are equations representing systems that change over time. For example, various kinds of waves including sound waves can be represented by partial differential equations. Studying how waves scatter when encountering objects or other waves---for example, sound waves bouncing off walls and other objects in a concert hall---is the goal of scattering theory. Within mathematics, scattering theory examines similar issues in more-abstract settings, by examining how solutions to partial differential equations interact over time.
The prize-winning paper of Andras Vasy resolves a 35-year-old conundrum in geometric scattering theory and develops a systematic framework for analyzing certain partial differential equations. Although it appeared only in 2013, the paper has had a major impact and stimulated much subsequent research, some of it by Vasy and his co-authors. The prize citation also recognizes "Vasy's outstanding contributions to multi-body scattering and to propagation of singularities for solutions to wave equations on regions with singular boundaries."
Andras Vasy received his PhD in mathematics from the Massachusetts Institute of Technology in 1997. He was on the faculty of the University of California, Berkeley, and of MIT before taking his present position of professor of mathematics at Stanford University. He was a Clay Research Fellow (2002-2004) and an Alfred P. Sloan Research Fellow (2002-2004).
