  • ABOUT
  • PUBLICATIONS

I obtained my PhD from Imperial College, London just before moving to Australia in 1978. Since then, I have mostly worked at the Australian National University, as Professor of Chemistry and have also served as Dean of the Faculty of Science, Chair, Board of the Faculties and as DVC(Education). In 2009, I was appointed the Founding Chief Investigator of the new National Centre of Excellence in Desalination, Murdoch University, Perth. I took up my current position as Research Professor at the University of New South Wales, Australian Defence Force Academy, in Canberra, in September 2010. My main research interests are in: Water treatment and purification, water recycling, desalination, membrane filtration and fouling. Emulsion and colloidal stability and flocculation. Properties of electrolyte and surfactant solutions. Experimental and theoretical study of forces between surfaces and colloidal particles. Recent Publications: M.J. Francis, R.M. Pashley and M.
