**Abstract:** In an inverse scattering problem, we attempt to reconstruct information about unknown objects based on how acoustic or electromagnetic waves scatter off of them. These problems have applications in nondestructive testing and in identifying the location of hidden objects, such as underground material resources or defects in structures. In this talk, we discuss methods for quickly and accurately solving this type of problem when only limited measurements of the scattered field are available.

**Speaker Bio:** Jacob Rezac is a Ph.D student in Applied Mathematics at the University of Delaware, where he is studying computational and theoretical approaches to inverse scattering theory. He has worked in the Computational Science and Mathematics Division at Oak Ridge National Labs and as a research assistant in the Center for Applied Mathematics at Ecole Polytechinque. Rezac received a B.S. and M.S. in Applied Mathematics from the Colorado School of Mines.

**Note:** Visitors from outside NIST must contact Cathy Graham; (301) 975-3800; at least 24 hours in advance.
