I usually teach inorganic chemistry to one year group of chemistry students at University College, but occasionally do more including first year physical chemistry.  I teach core inorganic chemistry to 1st, 2nd and 3rd year MChem students at several other colleges in Oxford and have done this for more than 20 years.


My research has focussed on studying the electronic structure of cyanide-bridged mixed valence transition metal complexes.  Originally through optical, nonlinear optical and electrochemical methods, my most recent work hinges around using electron and nuclear magnetic resonance spectroscopies to investigate the electronic coupling between indirectly linked metals through the distribution of unpaired electron spin density in these paramagnetic systems.
