SRC Research Fellow 1968-1970

Emeritus Professor 2003 -

Brian Roberts is a distinguished mechanistic organic chemist who specialized in the study of organic radicals.

Brian Roberts came to UCL as an undergraduate, graduating with First Class Honours in 1965. He studied for a PhD with Alwyn Davies. He stayed on as a SRC Research Fellow from 1968-70, then as Turner and Newall Research Fellow. In 1971 another SRC fellowship took him to work with Prof. John Perkins at the now defunct Chelsea College. He returned to UCL the following year as a Lecturer, and was awarded the Royal Society of Chemistry's Meldola Medal in 1973. He was promoted to Reader in 1982. In 1996 he won the RSC's award for Organic Reaction Mechanisms and was made Professor in 1999. He retired in 2003 and was awarded Professor Emeritus status by UCL's Provost.

Brian made his name studying free radicals in organic and organometallic reactions. In particular he was interested in the reactivity of radicals and their use in polarity reversal catalysis. Brian made much use of EPR spectroscopy and one of his CW magnets, equipped with new electronics, is still running in Dr Chris Kay's lab over in the Biochemistry building.
