Glenn has worked at NASA GSFC since October 2012. He is a member of the 614 In Situ Observations Laboratory, which supports NASA Earth Science objectives with measurements of trace gases (formaldehyde, ozone, NO2, and greenhouse gases) on multiple airborne platforms. He has participated in numerous airborne missions, including PEGASOS, SENEX, SEAC4RS, CONTRAST, WINTER, SONGNEX, KORUS-AQ, CARAFE, OWLETS, ATom, FIREX-AQ, BlueFlux, ACCLIP, GOTHAAM, and AEROMMA. He is a regular participant in the NASA student airborne research program (SARP).
Glenn's research involves novel applications of airborne observations, including 1) quantifying surface-atmosphere exchange to understand the source and sinks of trace gases, 2) synthesis of airborne and satellite observations to constrain global atmospheric chemical processes, and 3) analysis of interconnected chemical systems through numerical modeling. Glenn is the maintainer of the Framework for 0-D Atmospheric Modeling (https://github.com/AirChem/F0AM), a widely-used software package for simulating atmospheric chemistry.

Prior to arriving at NASA, Glenn was a NOAA Climate and Global Change Post-doctoral fellow at University of Wisconsin, Madison, WI. He holds a B.A. in Chemistry from Johns Hopkins University and a Ph.D. in Chemistry from University of Washington. He is also an Eagle Scout.
