Biographical Details

Steve Colbran gained his Ph.D. from the University of Otago, New Zealand, in 1984. He then undertook post-doctoral research with Professor the Lord Jack Lewis, FRS, and Professor Brian Johnson, FRS, at the University Chemical Laboratories, University of Cambridge, England, 1984–1987. Steve was appointed to the academic staff of UNSW in 1987, and he spent 1994 on leave from UNSW as a Visiting Scientist in the Department of Chemistry, Massachusetts Institute of Technology, USA.

Research Interests

Steve Colbran's research expertise is in transition metal chemistry and (spectro-)electrochemistry.

Current research interests:

  • Biological catalysis: using computational and synthetic models to uncover insights about multi-electron redox processes in biology; for example, in respiratory proton pumps, in nitrogen reductases and in metallo-(de)hydrogenases.
  • Bio-inspired catalysis: using insights from metallo-protein catalysts to design and realise new transition metal catalysts for multi-electron reduction processes.
  • Catalyses for a sustainable future: energy-efficient catalyses of the multi-electron reduction of carbon dioxide to methanol fuel.
  • Design, synthesis and use of transition metal systems with redox-active, multifunctional ligands.
  • Copper chemistry and its relevance to biology and medicine.
