Dr Stephen Fletcher
Steve was born in Halifax, Nova Scotia, Canada. He received a First Class undergraduate degree from Mount Allison University in 1999, and obtained his PhD at the University of Alberta in 2005. In 2005 he was an NSERC of Canada postdoctoral fellow in Groningen, The Netherlands, and in 2007 worked as a research associate at the University of Manchester. He started at the University of Oxford in 2009 as an EPSRC Career Acceleration Fellow and has been teaching organic chemistry at Hertford since October 2010.
Steve teaches 1st, 2nd and 3rd year organic chemistry at Hertford.
Steve supervises several Masters and DPhil students in the field of organic chemistry.
Steve’s research focuses on the area of synthetic organic chemistry. His group is developing new catalytic asymmetric methods for carbon-carbon bond formation. The group also builds model systems to study important processes in chemistry and biology such as the conversion of light into mechanical energy (by building new ultrafast and efficient chromophores), the origins of life (by making self-reproducing systems) and the development of functional materials and molecular machines .
