One of my favorite places to talk with people about research is the Wednesday Nite at the Lab series from the UW–Madison Biotechnology Center. It's always a great local audience, and Wisconsin Public Television has often taped these lectures for broadcast across the state.
In 2017 I visited just after our team's publications describing the Lesedi Chamber fossil material and the geological age of the Dinaledi Chamber fossils. I was able to share some video from inside the cave system, showing some of the extraordinarily difficult contexts where the team works.
