In today’s episode I speak with my friend, Dr Andreas Kisling Harris. I loved this conversation and hope you do too. He’s a scientist who started out as a theoretical physicist and worked his way into the field of bacterial genetic engineering. He’s working on a technology that would harness the 'chemical warfare' that goes on between bacteria, in order to extract new antibiotics and industrial chemicals. We talk about his fascinating path to what he’s doing; the advantages of a scientific education; cross-disciplinary study; the problems and strengths of scientific institutions; the things that allow him to do what he's doing; the amazing - mostly untapped - potential of bacteria to provide us with useful chemicals; and much more.
