About Stephen Gray

Professor Stephen Gray has had a focus on water and membrane research for over 27 years.

He is part of research teams that:

  • are working towards commercialisation of membrane distillation
  • have introduced ceramic membranes to Australian industry
  • are working to demonstrate membrane integrity monitoring technology.

In the field of membrane fabrication he has projects that span:

  • nanocomposite UF membranes for increased abrasion resistance
  • nanocomposite pervaporation membranes for niche applications
  • ceramic membranes for desalination
  • small pore size metal membranes.

In 2013 he was recognised as Thought Leader in Lux Research's international review of water research. He is currently President of the Aseanian Membrane Society, Editor of the Journal of Water Reuse and Desalination, and on the editorial board of Water Research and Desalination journals.

Qualifications

  • PhD (Chemical Engineering) University of Melbourne, 1992
  • BE (Chemical Engineering) University of Melbourne, 1985
