Dr Evans was a pioneering researcher in the field of glutamate receptors whose reputation endures partly because of his discovery of the Mg2+ block of the NMDA receptor, together with his contributions to the discovery of the kainate receptor.  

In an obituary published in the journal Neuropharmacology, Dr Evans is cited as "a key reason why the Pharmacology Department at the University of Bristol established itself in the ‘70s and ‘80s as the leading centre for glutamate receptor research worldwide”.
