Group Members

James Cho
Professor James Cho (joint with Applied Mathematics) works on astrophysical-geophysical fluid dynamics.  This includes planetary atmosphere/ocean and climate; exoplanets; compact objects and astrophysical disks; and, turbulence, vortex dynamics, and nonlinear  waves.  These activities utilize advanced mathematical methods  and/or numerical simulations for fundamental theory as well as for interpreting observational data.
Albion Lawrence

Professor Albion Lawrence works in physical oceanography and geophysical fluid dynamics.  His activities span from fundamental questions in geophysical turbulence to the analysis of observational oceanographic data.

Black hole in orange against a black night sky

Sgr A* (pronounced Saj-A-star) is the largest black hole in our night sky, but we don't know what it looks like up close because we've never been able to take a picture of it.

For the last four years, professor of astrophysics John Wardle has been working with a team of roughly 200 scientists and engineers to create our first ever picture of Sgr A*.
