Annette Koo

• Technical leadership and strategic oversight
• Comparison analysis
• Goniospectrophotometry, scattering distribution functions

• PhD, Physics, 2005

Annette completed a physics PhD through Victoria University of Wellington in 2005 and then spent 3 years in Melbourne as a postdoctoral fellow at CSIRO and then at Monash University doing research into catalysts for solar hydrogen generation.

In 2008 she started at MSL as a research scientist, developing expertise in the measurement of light and human perception, including the design of MSL’s robot-based goniospectrophotometer and piloting the CCPR comparison of spectral transmittance.

Since late 2021 Annette has been the Chief Metrologist for MSL. The Chief Metrologist is a verifying authority for measurement standards under the National Standards Regulations 1976 in relation to the verification and reverification of any standard or standards of measurement. The main duty of the role is to ensure the integrity of the measurement system in New Zealand. In practice, the Chief Metrologist needs to be satisfied that measurement results provided by MSL are traceable to the SI (the International System of Units) and that measurements carried out in NZ by IANZ-accredited laboratories can be traceable to the SI by relying on verified measurement results supplied by MSL.

• Member of the Metrology Society of Australasia
• Represents MSL at the CCPR and is chairperson of task groups of the CCPR working group
• Member of CIE technical committees
