Biography Summary

Prof. Pejoohan Tavassoti is an Assistant Professor and the Jr. Norman W. McLeod Chair in Sustainable Pavement Engineering at the Department of Civil and Environmental Engineering at the University of Waterloo, where he is closely working with the Centre for Pavement and Transportation Technology (CPATT). Prior to joining the University of Waterloo, Prof. Tavassoti worked as an Assistant Research Professor at the Thomas D. Larson Transportation Institute of the Pennsylvania State University. His research revolves around promoting sustainability and resilience of the transportation infrastructure with a focus on an enhanced pavement engineering, design, and materials characterization framework. To this end, he has been actively working on collaborative research with several colleagues from across Canada and internationally for over the past 12 years. In 2020, Prof. Tavassoti was elected to serve a 5-year term as the vice chair of the Ontario Asphalt Expert Task Group (OAETG), where he is currently working with experts from the academia, transportation industry, government agencies, municipalities, and consultants to address some of the pressing issues affecting the quality of the pavement network in Canada.

At the international level, Prof. Tavassoti is an active member of the International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM). At RILEM, he is serving as the leader of the bituminous binders fingerprinting Task Group of the TC FBB. In this capacity, he is working with experts from over 18 different countries on utilizing advanced materials characterization techniques and Artificial Intelligence to bridge the gap between the chemo-physical properties of the bituminous mixes and their performance characteristics. Prof. Tavassoti is also the co-founder of the National Transportation Infrastructure Research Center (NTIRC) at the K.N.Toosi University of Technology, where he used to serve as the core faculty member until 2012.
