The award, judged by process chemists from these four companies, recognises his work ‘using physical organic chemistry to understand reaction mechanisms’.

Professor Lloyd-Jones will give a lecture at the annual Society of Chemical Industry (SCI) Process Development Symposium in Cambridge in December, where the prize will be formally awarded.

This is the second year running that a Bristol chemist has won this award; Professor Varinder Aggarwal was the 2009 recipient.
