Thought this podcast may be of interest to you guys. It's from Boise State's (where I went to school and work with now) Beyond the Blue program, which is a podcast series that spotlights various academics from the university.
This one is from Amy Moll, who is a professor of material science and engineering and she was also involved in PBS's Nova: Making Stuff documentary series.
