Senior mentors

Time passes and with it my three most influential colleagues and dear friends.

  • Emeritus Professor Rolf Prince AO etc, probably the most well known chemical engineer in Australia and one of the discipline's foremost elder statesmen.
  • Colin Putt the genius of ICIANZ, who also taught at the University of Sydney was a living encyclopaedia of knowledge and wisdom.
  • Professor H.M. Tweeddale is missed for his excellent counsel in professional engineering, high ethic standards and expert knowledge.


  • Dr Raj. Malik, a long-time associate and collaborator on biological process engineering, process control and HAZOP studies. His company Biospot, which specialises in biological treatment of wastewater, can be viewed at
  • Dr Brett Alexander, a PhD in chemical engineering with eclectic abilities.
