Raheleh Givehchi



I am currently an NSERC Post-Doctoral Fellow at the Department of Civil Engineering at the University of Toronto (U of T). I received my PhD in Mechanical Engineering from the University of Waterloo, as well as M.S. and B.Sc. in Civil Engineering from Sharif University of Technology in Iran.

Research Interests

My research interests include sustainable buildings, indoor air quality, airborne nanoparticle filtration, and indoor nanoparticles.
