I completed my BSc and PhD in Chemistry at the University of Otago (PhD supervisors D. A. Buckingham and C. R. Clark), New Zealand. After a 6 month postdoc with Professor W. Buckel, Philipps University, Marburg, Germany, I accepted a prestigious Alexander von Humboldt Research Fellowship, to work with Professor R. van Eldik at the University of Erlangen-Nuremberg, Germany. I then spent a year as an NIH postdoctoral fellow working with Professor R. G. Finke at Colorado State University, USA. From 1998 to 2002 I was a Research Group Leader and the Rita Cornforth Research Fellow in the Research School of Chemistry, The Australian National University, Australia. In 2003 I took up an Assistant Professor position in the Department of Chemistry and Biochemistry at Kent State University, USA, and was subsequently promoted to Associate Professor (2008) and Professor (2013). In July 2014 I moved from the US to my current position in the School of Applied Sciences at AUT.
