Research Interests

I study gas giant planet and brown dwarf atmospheres in an effort to better understand the formation and evolution of these objects. I also search for directly imaged young planets to try to constrain formation environments of actively accreting planets.

I use Spitzer secondary eclipses to probe the thermal emission of gas giant planets. I've searched for trends in the atmospheric metallicity of cool planet atmospheres and looked at the population of all gas giant planets with Spitzer secondary eclipse detections to see if we can find population-level trends in circulation patterns and atmospheric chemistry

Using high-resolution spectra obtained from NIRSPEC on Keck, I study the the atmospheric compositions of ultra-cool brown dwarfs. I am currently working on doing atmospheric retrievals of late-T brown dwarfs using this data to try to ascertain why atmospheric models are notoriously poor matches to the data of these objects. 

Characterization of Protoplanetary Disks Directly Imaged with Keck/NIRC2

Using NIRC2 on Keck, I directly image protoplanetary disks in an effort to directly detect young planets that could be forming in them. I also directly model these disks to better understand the physical morphologies and dust grain distributions of these disks at infrared wavelengths. You can see one of our recent papers on the young planetary system PDS 70 here.
