About

Dr Bernie Dawson is a scientist in wood processing research. He specialises in coatings and surface technologies that improve the performance of wood in service. Bernie’s current research is focused on supercritical carbon dioxide dewatering of radiata pine and reducing distortion in difficult-to-dry hardwoods such as Eucalypts nitens through alternative drying methods.

Research capabilities

Research in a range of wood and surface technology areas:

  • Dewatering of green softwoods and hardwood using supercritical carbon dioxide to reduce stresses usually developed with conventional drying.
  • Influence of texture and coating type on weathering performance of coated wooden products.

    Career highlights

    • Member of the International Organising Committees for the All Division 5 IUFRO Conferences in Rotorua (2003) and Taipei (2007).
    • Elected as Fellow in the International Academy of Wood Scientists (2008).
