The Landau equation is a mesoscopic model in plasma physics that describes the evolution in phase-space of the density of colliding particles. Due to the non-local, non-linear terms in the equation, an understanding of the existence, uniqueness, and qualitative behavior of solutions has remained elusive except in some simplified settings (e.g., homogeneous or perturbative). In this talk, I will report on recent progress in the application of ideas of parabolic regularity theory to this kinetic equation. Using these ideas we can, in contrast to previous results requiring boundedness of fourth derivatives of the initial data, construct solutions with low initial regularity (just $L^\infty$) and show they are smooth and bounded for all time as long as the mass and energy densities remain bounded. This is a joint work with S. Snelson and A. Tarfulea.

Optical tomography is the process of obtaining full (3D) reconstructions of the interior optical properties of an object from observations at the boundary. In mathematical terms, this amounts to reconstructing the coefficients of a PDE from measurements of the solutions at the boundary; which PDE is involved depends on which model we use for light propagation. In this talk I'll introduce an optical tomography problem in which we model light propagation by a radiative transport equation, and describe a recent result that allows us to do reconstructions even when our measurements are restricted to a subset of the boundary.
