Most of our topics on this podcast have been focused on established industries and businesses we've all heard of before.  But there's a lot going on right now with small business and entrepreneurship.  We're seeing more investment from PE firms and family offices in start-up ventures especially in the medical field.  So we thought we'd reach out to an expert in this area.  Greg Saltsman talks with Cameron Cushman, Director of Innovation Ecosystems at the University of North Texas Health Science Center.
