After nearly 10 years in academic physics departments, the transition into a postdoc in a top synthetic biology lab was a rough landing. Four years later, I left the academic world for a position in industrial biotechnology as a scientist at LS9, a startup focused on engineering bacteria to make biofuels and commodity chemicals. Then, three years ago, I left LS9 to co-found a startup called Industrial Microbes, where we are engineering the central metabolism of microorganisms to enable them to use natural gas as a raw material for chemical production. As the toolkit of synthetic biology has expanded, the skills needed to succeed as a scientist in industrial biotechnology now include more than just molecular biology, analytical chemistry, an...
