Title: Radiative transport and optical tomography

Abstract: Optical tomography is the process of reconstructing the optical parameters of the inside of an object from measurements taken on the boundary.  This problem is hard if light inside the object is scattered -- if it bounces around a lot and refuses to travel in straight lines. To solve optical tomography problems, we need a mathematical model for light propagation inside a scattering medium. In this talk I'll give a brief introduction to one such model -- the radiative transport model -- and talk a little bit about its behavior and its implications for optical tomography.
