Frej Mighri obtained his Bachelor (1987) and PhD (1998) from École Polytechnique of Montreal, and his Master degree in mechanical engineering from Université de Sherbrooke (1989). He worked during four years (1989-1992) as senior engineer at CETIME, a Tunisian government organism, where he had set up in collaboration with the United Nations the first Laboratory in the country for polymer characterization. After his PhD, he joined the Industrial Materials Institute, IMI, National Research Council Canada (Boucherville, QC), in the first time as a Postdoctoral trainee (NSERC fellowship) (1998-1999) then as a research officer (1999-2003). Since 2003, he joined Laval University where he is presently acting as full professor. He is highly involved in research with main interests in the development of high performance polymer systems, including correlations between the process, structures and final properties of the developed materials. He was Head of the graduate studies, Chemical engineering (2008-2014) and was Head of polymer processing program (2005-2009). He was Head of the graduate studies, Chemical engineering (2008-2014) and was Head of polymer processing program (2005-2009). He is acting since 2006 as a member of the Director’s board of the Research Center for High Performance Polymer and Composite Systems, CREPEC, a strategic inter-university’s cluster.
