Senior Research Associate
I'm interested in computational astrophysics broadly — understanding
complex astrophysical systems through large-scale parallel multiphysics
simulations; carefully examining microphysics both for its own sake
and so that it can be included quantitatively in larger-scale models;
and developing and analyzing computational techniques for use in
I study interfacial
instabilities, buoyant flows,
and combustion problems
with applications to Type Ia supernovae, which are
interesting in themselves and very important for quantitative cosmology;
magnetic draping in galaxy
clusters; and fragmentation and wind-interactions in disks. I have
also recently worked on the physics of mixing and enrichment in
detonations, galaxy formation, and efficient and accurate
for studying these phenomenon.
You can look at my CV or download it in
PDF. A description of some of my present research directions is also available,
as is my publication list, as well.
This summer, with Jonathan Sievers,
I taught a week-long summer school at SciNet on Parallel Scientific Programming;
we had taught a similar course for astrophysicists at CITA the previous year.
We have also taught a Department of Astronomy mini-course entitled Scientific Computing for Astro Grad Students.
In winter 2008, I taught AST222, “Galaxies
and Cosmology”, and I have been invited to teach it again.
I also recently had the opportunity to teach a course entitled The Search for Life in the Universe
at The School of the
Art Institute of Chicago. It covered a lot of material —
astronomy, planetary science, chemistry, biology — and was
a lot of fun. You can find a description of my approach to teaching online or as
The UChicago Chronicle has a nice
article about when we won a Gordon
Bell Award with a very large simulation with the FLASH code (a code I was/am
a developer for).
