I study the climate of exoplanet and brown dwarf atmospheres, in particular researching the dynamics, temperature structures, chemistry and clouds that affect the observable properties of these atmospheres, focusing on the 3D aspects of planetary atmospheres.
For this I use state of the art atmospheric hydrodynamical models, so called, general circulation models (GCMs). I am a lead developer of the Exo-FMS GCM model, as well as having experience with the THOR and MITgcm GCM models.
I add specialized physical processes to these models such as radiative-transfer of various flavors (e.g. grey, non-grey and correlated-k), cloud formation physics and kinetic chemistry modeling.
I also develop true 3D radiative-transfer techniques for highly accurate modeling of radiation through a global atmosphere. I am the lead developer of the gCMCRT model, a Monte Carlo RT model that uses GPU technology to accelerate computational times. This can be used to calculate albedo, emission and transmission spectra, as well as perform phase curve calculations. This model can also be used at high resolution, computing the Doppler and rotational shifting of lines, allowing theoretical models to be used to physically interpret high-resolution observational data in detail.
My 1D two-stream RT suites and the 3D gCMCRT model are available on my GitHub.
