For this episode, we spoke to Marty Martin from the Big Biology podcast - the best biology podcast around (excluding our own, of course)! Dr. Martin is a professor and biologist at the University of South Florida. Along with co-host Art Woods, he covers some of the biggest unanswered questions in biology. We ask about his research into sparrows as a real-world immunological model, and ask how podcasting complements his work as a professor and researcher.
