The Power of Biocatalysis Advancing Organic Synthesis

Our interdisciplinary research team works at the interface of chemical synthesis and modern life sciences — engineering proteins, enzyme cascades, and synthetic cellular factories to address challenges such as sustainable chemical production.

Research

Three core technologies The toolkit behind our science — chemical catalysis, engineered biology, and the computational methods that connect them. Each feeds the others: catalysis defines the chemistry, engineered proteins and microbes run it, and machine learning steers the design–build–test loop.
