About Stephen Gray

Professor Stephen Gray has had a focus on water and membrane research for over 30 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 a Co-Editor in Chief of the Water Reuse journal (IWA Publishing), and is on the editorial board of the Water Research and Desalination journals.
