Prof. Dek Woolfson

CSO

World leader in protein design with extensive track record of commercial partnerships. In 2011 and 2014 Dek’s group published landmark papers in Nature Chemical Biology and Science describing a new protein structure, which they called alpha helical barrels.  These have central channels that allow binding and fluorescence change upon binding by analytes or complex mixtures. This provides the basis for the Pandra technology. Dek is the founding Director of BrisSynBio – a £13 million Synthetic Biology Research Centre – and the Bristol BioDesign Institute at the University of Bristol. His work has been featured in Nature Chemistry (cover story), Nature Chemical Biology and Science. He is the recipient of multiple science awards from bodies including the Royal Society and the Royal Society of Chemistry.
