Travis earned a Bachelor of Science in Chemistry with a minor in physics from Northwest Missouri State University in 2004. From there he continued his education by earning a PhD in analytical chemistry by studying Arctic ozone depletion events in Paul Shepson’s lab at Purdue University. Travis came to NASA’s Langley Research Center in 2010 as a NASA post-doctoral fellow where he studied air quality at the Chemistry And Physics of the Atmospheric Boundary Layer Experiment (CAPABLE) site in addition to participating in multiple field campaigns. Part of this experience involved carrying out measurements from balloon-borne sensors (sondes) to evaluate and validate satellite retrieval products. Beginning in 2013, Travis began working with the SAGE III/ISS team on validation techniques and then joined the team as a validation scientist in 2016. Since 2019, his focus broadened to stratospheric aerosol research in general.

In his free time Travis enjoys spending time with his family, doing house/auto repairs, as well as being an avid reader of history and theology.
