This week on Careers in Discovery, we’re joined by Martin Brenner, CEO and CSO of iBio and one of Biotech’s most experienced R&D leaders. Martin shares his journey from pharmacologist to global R&D executive, with leadership roles at Pfenex, Recursion, AstraZeneca, and Stoke Therapeutics. Now at iBio, he leads a company developing gene therapies for rare diseases - while applying lessons from decades of drug development to a new generation of science. We talk about the power of simplicity in communication, why leaders need to create space for science to breathe, and how to build R&D teams that are lean, smart, and focused on what matters most.
