I have spent the past eight years of my career in the fields of biocatalysis and synthetic biology, working both in industry and academia. My work has focused on engineering various enzymes (carboxylic acid reductases, alcohol dehydrogenases, ene-reductases and lipases) to be used as biocatalysts in the pharmaceutical, flavors, fragrances and food industries. The methodologies I have used and helped to develop, range from the creation of smart libraries of mutants to the development of high-throughput screenings to select for the improved mutants. My projects have always been co-funded by industry (GSK and DSM), a testimony to their applied interest.
Having worked in the first start-up company in the UK dedicated to synthetic biology (Synthace) has helped me to better understand the challenges we still need to overcome to transform biology into the engineering discipline of the future – in particular, issues of data reproducibility and big data management.
