Steven is a co-founder of Isomerase and is highly practiced at applying the chemical biology to drug discovery. In particular, Steven is experienced in applying Isomerase's bioengineering platform and semi-synthesis to generate microbial natural products with characteristics more suited to use as pharmaceuticals than the parent, and taking these discoveries through into manufacturing. From 2009 until 2013, Steven was the Director of Natural Products Chemistry at Biotica Technology Ltd., where he was responsible for all internal fermentation and chemistry as well as the management and technology transfer associated with outsourced manufacture and chemistry. Steven joined Biotica in 2002 as a Research Scientist and worked on a number of different microbial natural product based programmes across multiple therapeutic areas. Prior to that, he spent two years as a Post-Doctoral Research Associate with Professor Heinz G. Floss (University of Washington, Seattle) studying the biosynthesis of ansamitocin. Steven holds a BSc and PhD in Chemistry from the University of Durham, where he studied under Professor David O'Hagan. He is an author or inventor on over 50 scientific papers and US/EU patents.
