Brahim Benyahia graduated with an MEng ("Diplôme d'Ingénieur") in Chemical Engineering from the National Polytechnic School, Algeria. He completed a PhD in Chemical Engineering, at the ENSIC (Engineering School of Chemical Industries) France, in December 2009, then moved for a postdoc associate position at Massachusetts Institute of Technology (MIT) USA, where he focused for 2.5 years on the development of the first end-to-end integrated continuous pharmaceutical manufacturing platform (a $65 M Novartis-MIT project). In 2013, Brahim joined Loughborough University as a lecturer in Chemical Engineering and was promoted to Senior Lecture in 2017 then to Reader in 2022. He became professor of Chemical Engineering in 2023.
