Dr. Khoshnazar teaches civil engineering materials courses. In Winter 2018, she teaches “High Performance Concrete” course at the undergraduate level.

Dr. Khoshnazar is currently accepting applications for undergraduate, master’s and doctorate students in the area of novel and sustainable cement-based materials. If you have excellent qualifications, and are motivated and passionate to peruse research in this area, please send your CV and a cover letter (maximum one page) describing how your interests and qualifications fit the position to “rahil.khoshnazar@ucalgary.ca.”

Research activities 

Dr. Khoshnazar’s research projects involve the application of nanoscience and nanotechnology for the development, characterization and engineering performance assessment of advanced and sustainable cement-based materials. Her current projects are related to cement-based systems incorporating calcined clays.   



Dr. Khoshnazar joined the Department of Civil Engineering at the University of Calgary in November 2017. Prior to starting her job at the University of Calgary, she worked as an NSERC postdoctoral fellow at McGill University. Her postdoctoral research focused on the characterization of the micro-/nano-structure of green concrete materials produced by the carbonation curing technique. She received her PhD degree in Civil Engineering from the University of Ottawa in 2015. During her doctoral program, she worked on the nanostructural modification and performance assessment of hydrated cement-based materials at the National Research Council Canada in Ottawa. Dr. Khoshnazar also worked for four years at the Construction Materials Institute at the University of Tehran, where she completed her BSc (2008) and MSc (2010) studies.
