Welcome back to Innovation in the 'Burg, a podcast all about science and innovation in St. Petersburg. This week, Alison Barlow, executive director of the St. Pete Innovation District, hosts the brains behind Pure Molecular: John Paul and Bob Ulrich. Joining as community member is Jason Mathis of the St. Pete Downtown Partnership. Paul and Ulrich first co-founded Pure Molecular with technology to identify fraudulent fish (particularly grouper) in the marketplace. Now, the application of that technology has expanded to red tide detection, and biomedical applications. They talk building and scaling a business based in scientific research, and share where they're going next. Mathis talks priorities as CEO of the Downtown Partnership, communicating the Innovation District's story and how marine science and its applications uniquely position St. Pete as a future city.
