Hamid Salehi

Dr Hamid Salehi BSc, MSc, PhD, ALTHE

Senior Lecturer in Chemical Engineering

Dr Salehi is currently a Senior Lecturer in Chemical Engineering in the Faculty of Engineering and Science after joining the University of Greenwich as a Research Fellow with the Wolfson Centre in April 2018. He was a Research Associate for one year at the Biomass Technology Centre (BTC), of the Swedish University of Agricultural Science. His work was focused on the development of a new method for quantifying the flow properties of biomass particulate solids.

Salehi obtained his bachelor's degree from Isfahan University of Technology and continued his academic endeavours up to the PhD degree. He completed his MSc studies at the Lund University (LTH) and his PhD at the University of Salerno (powder technology group). His doctoral dissertation was on the evaluation of powder flow properties at low consolidation stress in collaboration with Anton Paar Company.

Dr Salehi carries over 8 years of work/research experience in various disciplines of particulate material technology, food and chemical engineering. He is the author of more than 15 scientific peer reviewed journal papers in high impact journals. Dr Salehi current research interests include studying the flow properties of conventional powder and of biomass particulate solids and the assessment of traditional and innovative characterization methods as well as linking particle characteristics to bulk properties.
