Dr Hessam Jahangiri AMIChemE, MRSC, FHEA

Lecturer in Chemical Engineering


I am a lecturer in Chemical Engineering at Sheffield Hallam University. My main research expertise is in renewable energy and sustainability, focusing on the thermal conversion of biomass (Pyrolysis, Gasification, Fischer-Tropsch Synthesis and Catalysis) to produce valuable fuels.


I received my PhD in Bioenergy and Catalysis from Cranfield University in collaboration with Aston University and completed an MEng degree in Chemical Engineering from the University of Birmingham. After my PhD, I worked at the School of Chemical Engineering, the University of Birmingham, as a Research Fellow prior to my Lecturer position at Sheffield Hallam University.
