Biographical details

James Bull graduated from the University of Cambridge in 2001 with a First Class Honours MSci degree in Natural Sciences, Chemistry and the Raphael Prize for Organic Chemistry. He then spent a year working at GlaxoSmithKline Stevenage as a Research Scientist in the Medicinal Chemistry Department.

He returned to Cambridge in 2003 to undertake PhD research with Professor Steven V Ley. He completed the total synthesis of bisoxazole antifungal natural product bengazole A and analogues.

In 2007 he joined the group of Professor André B. Charette as a Postdoctoral Fellow at Université de Montréal, Canada. Here he developed an intramolecular Simmons-Smith cyclopropanation reaction.

In 2009 he began independent research at Imperial College London as a Ramsay Memorial Research Fellow (2009-2011), working in the laboratories of Professor Alan Armstrong. From 2011 to 2015 Dr Bull held an EPSRC Career Acceleration Fellowship on "Novel strategies to access chiral heterocycles as potential lead compounds in drug discovery". In January 2016 Dr Bull started a Royal Society University Research Fellowship.
