BIO
I'm a protein engineer, synthetic biologist, and computer scientist. I studied computer science at MIT (SB/MEng) and then synthetic biology at Cambridge (PhD) and UCSD (postdoc). After two years as a scientist at Bolt Threads engineering yeast for protein production, I moved to the University of Colorado Boulder to work on a DARPA project using protein engineering to turn plants into chemical biosensors. My co-founder Matt and I founded Ohmic to make plants resistant to disease.
Ex-company, school and discipline below are derived from this bio. Nothing is inferred when the bio is missing.
