I have been a Federal Civil Servant since 2009, when I joined the Space Sciences Division of the Naval Research Laboratory (NRL). While at NRL, I was the co-leader of ONR-funded projects that produced the first coupling between whole atmosphere and ionosphere (SAMI3) models using ESMF. Prior to NRL, I was a Project Scientist at the National Center for Atmospheric Research (NCAR), where I was the sole developer of the first version of the Whole Atmosphere Community Climate Model (WACCM). Following my NCAR/ASP post-doctoral appointment, I have worked with UARS satellite data investigating the synoptic structure of water vapor in the upper troposphere, tracer distribution in the middle atmosphere, and tidal variability.
I was one of the founding members of the SPARC/DynVar initiative (http://www.sparcdynvar.org). I am a past member of the Middle Atmosphere Committee of the American Meteorological Society, and of the International Committee of the Middle Atmosphere (a committee of the International Association of Meteorology and Atmospheric Sciences – IAMAS).
In January 2023, I came to the Ionosphere, Thermosphere and Mesosphere Physics Laboratory of the Heliophysics Science Division of the NASA Goddard Space Flight Center, where my research has focused on the coupling between atmospheric regions, from the ground to the exosphere. I am leading an internally funded project (ISFM) to extend the GEOS model to the lower thermosphere with data assimilation from the ground to about 150 km. This ISFM is an inter-divisional joint venture between the Heliophysics and Earth Science Divisions at GSFC.
