Dr. Nokken obtained BASc and PhD degrees from the University of Toronto in 1999 and 2004, respectively. Her research is focused on the concrete performance and durability of concrete materials subjected to a number of deterioration mechanisms. She joined the faculty of Concordia in September 2004.



Dr. Michelle Nokken is an Assistant Professor in the Department of Building, Civil & Environmental Engineering. She obtained BASc and PhD degrees from the University of Toronto in 1999 and 2004, respectively.

Dr. Nokken's received several awards during her doctoral research including two consectutive NSERC post-graduate scholarships and a fellowship from the Portland Cement Association.

Prior to attending the University of Toronto for her BASc and PhD degrees, Dr. Nokken worked in industry for several years. She was involved in projects such as: research concerning sustainable development projects; energy analysis of single and multi-family residential housing; design of passive solar, straw bale and log homes.


Membership in External Organizations

  • American Concrete Institute - Faculty Network, Committees 201, 231, 236.
  • American Society of Civil Engineers.
  • Professional Engineers of Ontario.



  • Development of on-site techniques to assess adequate curing and durability of concrete
  • Durability health monitoring
  • Repair and rehabilitation of civil infrastructure
  • Optimization of supplementary materials for sustainability and durability
  • Permeability and Pore Structure Development
  • Cemented mine backfill

Interested graduate students should have some knowledge of concrete properties and material behaviour, as well as a basic understanding of cement hydration and chemical deterioration processes in concrete. As a large part of the research for these projects is experimental, a willingness to get dirty and occasionally lift heavy objects is a plus.
