Episode #294: Drilling for Ashes - with Dr. Joanne Ballard

We met Dr. Ballard at the Cosmic Summit, and decided we'd love to have her on the podcast to discuss her work. She is a Geologist and Biogeographist, and a member of the Comet Research Group. She became interested in the YDIH and started drilling lake cores looking for evidence of biomass burning.
She joins us this episode to discuss her background, her interest in the YDIH, and her related field and lab work, as well as some of her current interests and possible future projects.
