Our guest is our very good friend James McCracken. We explore his career path from his post-doc at The University of Chicago, to becoming the Core Facility Director of the University of Louisville Diabetes and Obesity Center, to his current position as the Commercial Marketing Manager with Beckman Coulter Life Sciences. He has been deeply involved in the development of the newly released CytoFlex SRT cell sorter, so we also discuss the ins and outs of flow cytometry instrumentation development in industry.
