Joanne Zwinkels is a senior research officer with the Institute for National Measurement Stadnards, National Research Council of Canada (NRC).  She obtained her PhD in Physical Chemistry from the University of Alberta (1983) with specialization in the infrared optical properties of solids.  She joined NRC in 1984, to work in the fields of spectrophotometry and gloss and in 1991 was appointed the Head of the Photometry and Radiometry Group.  She has developed new instrumentation, procedures, and reference standards for high-accuracy spectrophotometry, spectrofluorimetry and gloss and her current research activities involve the development of a versatile reference goniospectrophotometer for specular gloss calibrations at several standard geometries and visual appearance characterization of gonioapparent materials.

Joanne is active in standards organizations and committees, such as CCPR, CIE and ISO, and professional societies such as ISCC and CORM.  She is the current President-of the ISCC (2004-2006), a past member of the ISCC Board of Directors, the Canadian delegate to the CCPR, the NRC liaison to CORM, the Vice President of the Canadian National Committee of the CIE, the Canadian member for CIE Division 2, the Chair of a CIE technical committee on fluorescence measurements, and a member of several CIE and ISO committees on the characterization of spectrophotometers, geometric tolerances for colorimetry, practical daylight simulators and optical properties of paper.
