My research works on the intersection of water vapor, clouds, and climate, primarily through observations and modeling of stable Hydrogen/Triple Oxygen isotopes of water vapor.  My focus is in developing ways to tease apart the various processes, such as vertical mixing, that set the humidity profile and control low-cloud maintenance in subtropical, marine settings.  I use a combination of in-situ and remote sensing isotopologue observations, ideal column models, and output from isotopically-enabled versions of the LMDZ and GISS general circulation models.  More generally I am interested in the role of condensible gases in planetary atmospheres from local scales to global climate.  I also work on dust and water processes in the Martian atmosphere, particularly related to dust lifting/sand mobilization, and effects on long-distance imaging done by the MSL Curiosity Rover.
