Blair Hall

Principal Research Scientist

Radio Frequency

Areas of expertise

• Radio and microwave frequency measurements of power and scattering parameters
• Measurement modelling
• Measurement uncertainty
• Scientific software development


  • Dr. ès Sci. (EPFL)


Blair joined the Measurement Standards Laboratory in 1998 and has been responsible for setting up and maintaining national standards in radio and microwave quantities.
Blair trained as a physicist. He holds a doctorate from the Ecole Polytechnique Fédérale de Lausanne, Switzerland, for research into the atomic structure of nanometre-sized particles. He later worked as a post-doctoral fellow at the Swiss national metrology institute (METAS), studying the quantum Hall effect. In 1993, he returned to New Zealand to lecture in Physics and Electronics at Massey University.
