Colloquium
- Sparse Grid Discontinuous Galerkin Methods for High-Dimensional Transport EquationsIn this talk, we present sparse grid discontinuous Galerkin (DG) schemes for solving high-dimensional PDEs. We will discuss the construction of the scheme based on
- 3D radar wavefield imaging of comet interiorsThe Rosetta mission to comet 67P/C-G revolutionized comet science, but left major questions on the table. Are cometary nuclei primordial or are they collisionally-evolved as predicted by modern theories
- How to Gamble or Invest If You Must: A Large Deviations Approach The Kelly Criterion (a.k.a. expected log utility maximization) is a well-known criterion function used to select optimal repeated gambles or long-term portfolio investments
- Birth, Death, and Barcodes: Discretization of Continuous Attributes in Bayesian Network Structure RecoveryBayesian networks are graphical models that can be used to represent complex relationships between a large number of random variables. A
- Mathematical modeling of cell divisionCells are the basic unit of life. All life on earth depends on cells' ability to duplicate themselves. In order to divide successfully, cells must solve fascinating mathematics and physics problems, which this
- Critical matterI will discuss examples of novel soft condensed matter, such as liquid crystals, membranes, and rubber, with particular focus on ubiquitous thermal fluctuations that lead to phenomena qualitatively beyond Euler-Lagrange
- Mathematical modeling of hemostasis Hemostasis is the process by which a blood clot forms to prevent bleeding at a site of injury. The formation time, size, and structure of a blood clot depends on the local hemodynamics and the
- Flavors of Baroclinic Instability in the Global OceanBaroclinic instability is the fundamental mechanism responsible for large-scale and mesoscale motions in rotating, stratified fluids. In Earth's atmosphere, it produces weather systems in
- Will KleiberThe challenge of creating historical weather products for the United StatesAbstract: Historical gridded weather products are critical components in climate, hydrologic and ecologic applications. A large number of historical
- Stephen BeckerImaging, Optimization and RandomnessWe will take a look at some of the work going in my research group, including work on super-resolution imaging problems (and their associated ill-conditioned optimization formulations), robust
