Stefan Michalski earned a B.Sc. (Hons) in Physics and Mathematics (1972), trained as a conservator in the Queen's University Master of Art Conservation program, and then joined the Canadian conservation institute (CCI) in 1979. During his career, he has initiated the development of many CCI tools for helping preserve collections, including the Relative Humidity Control Module (1981), the Light Damage Slide Rule (1988), the Framework for Preservation of Museum Collections poster (1994), and the light damage calculator (2012). He was invited to participate in the committee responsible for the “Museums, Libraries, and Archives” chapter in the ASHRAE Handbook (1999), and co-authored the humidity and temperature specifications.

In partnership with the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM) and the Instituut Collectie Nederland, he developed the course Reducing Risks to Collections (2003–2011). The manual and software currently used by CCI for risk assessments in Canada was also developed during that partnership. In 2005, at the invitation of UNESCO and the International Council of Museums (ICOM), Stefan wrote “Collection Preservation,” a chapter in Running a Museum: A Practical Handbook. He was also a member of the British Standards committee responsible for writing the normative document PAS 198:2012: Specification for managing environmental conditions for cultural collections. He is now working on a book about the museum environment with Jim Druzik of the Getty Conservation Institute.
