Research

Professor Christine Winterbourn, winner of New Zealand’s top science and technology award – the Royal Society of New Zealand’s Rutherford Medal. Professor Winterbourn is the first woman to receive the award in its 20 year history.

Professor Winterbourn has published more than 250 scientific papers. Her field of research is the biological chemistry of free radicals and other reactive oxidants and their involvement in health and disease. Professor Winterbourn's focus is on understanding mechanisms of reactive oxidant production, the biochemistry of biological damage and the consequences for disease pathology.

Her current interests include:

  • the production of reactive oxidants by neutrophils and their involvement in microbial killing and inflammation
  • how neutrophils form extracellular traps (NETs)
  • how thiol proteins contribute to antioxidant defence and redox regulated cell signaling
  • biochemistry and cellular functions of mammalian peroxiredoxins
  • mechanisms of oxidative protein crosslinking
  • oxidant-antioxidant interactions in red blood cells
