# Jason Marshall

When not writing and hosting the Math Dude’s Quick and Dirty Tips to Make Math Easier podcast, Jason Marshall works as a staff research scientist at the California Institute of Technology (Caltech) studying the infrared light emitted by starburst galaxies and quasars. Before that, he was a postdoctoral scholar at NASA's Jet Propulsion Laboratory (JPL). Jason obtained a PhD from Cornell University, where he worked with the team of astronomers that built the IRS (nothing to do with taxes) instrument for the Spitzer Space Telescope and helped teach many physics and astronomy classes. In addition to these astronomical pursuits, Jason has many earthly interests: traveling the world, tinkering with technology, watching and playing soccer, and spending time with his wife, Shannon, fixing up their small but increasingly comfortable Los Angeles area home.
