Summary

Graeme Hogarth Research Image

Our work centres on molecular transition metal chemistry. Current projects include; the synthesis and study of diiron dithiolate complexes as biomimetic models for the iron-only hydrogenase enzyme, which is used in nature to convert protons to hydrogen, the use of well-defined gold clusters as precursors to gold nanoparticles for applications in heterogeneous catalysis, and the preparation of backbone functionalised dithiocarbamate complexes for applications in materials and biological processes.

Graeme Hogarth hails from the North East of England but studied for both his BSc (1983) and PhD (1986) at the University of Bristol, carrying out the latter in the group of Professor Selby Knox. He was then awarded a NATO post-doctoral fellowship to work with Professor Arthur Carty at the University of Waterloo, and here he also worked closely with Professor Todd Marder (now at Durham University). After a year at the Inorganic Chemistry Laboratory in Oxford working with Professor Malcolm Green, he was appointed to a lectureship at UCL in 1989. He has been at UCL for nearly 20 years, being promoted to Reader in 2001. He is a Fellow of the Royal Society of Chemistry and when not in the lab he can be found on a squash court or watching the Boro!
