I'm planning to obtain a bioengineering/bme masters degree for sure but I wasn't sure whether to pursue in a phd program afterwards if I want to startup a biotech company? I know it's too generic but I'm interested in biosensors,synthetic biology, and health. I currently have a physics/biophysics and applied math degree. Masters-> work in industry -> startup?or masters-> startup? masters->phd->industry ->startup? masters->phd->startup?
