For Me’lisa Crawford, talking about poop isn’t gross or impolite — it’s an important part of a day’s work. Crawford is a PhD candidate at Arizona State University in the School of Life Sciences who studies poop to learn how a high-fat diet can alter your microbiome, or gut bacteria. In this episode Meli'sa discusses:

• what poop tells us about our gut health
• how food deserts affect what we end up eating
• how she ended up as a grad student at ASU
• advice for advanced science degree students

"ASU KEDtalks: The Podcast" is a production of ASU Knowledge Enterprise.
