Lecturer in Geotechnical Engineering

Background

Background

Dr Sadegh Nadimi is an engineering scientist and Lecturer (Assist. Prof) in the School of Engineering at Newcastle University. He holds a PhD in Geotechnical Engineering from City, University of London and an MSc in Geotechnical Engineering from Newcastle University. Following the award of his doctorate, Sadegh moved to the University of Leeds as Post-doctoral Research Fellow to focus on tribology of particulate solids, working with Prof Mojtaba Ghadiri, FREng and Prof Anne Neville, FREng, FRS.

In 2014, Sadegh was awarded a full University Doctoral Scholarship to study the multiscale nature of soil at London Geotechnical Centrifuge Centre, City University of London, under the supervision of Dr Joana Fonseca and Prof Neil Taylor.  Before his PhD study, he joined an engineering consultancy for two years to supervise geotechnical site investigations.  He was involved in a world-class research project during his MSc at Newcastle University called the Round Robin Tunnel Test (organised by Universities of Cambridge and Napoli Federico II) to predict the centrifuge data by advanced finite element modelling.  He has gained a great deal of experience in repeatedly running large complex nonlinear numerical analyses.  He has been actively engaged in ground engineering research since the second year of his undergraduate course through his tutor’s industrial research work.

Sadegh is committed to advancing fundamental engineering research and teaching.  He is an associate fellow of the Higher Education Academy (AFHEA) and has been involved in teaching since 2015. In July 2016, Sadegh was awarded the prize for the best presentation at the Young Geotechnical Engineers Symposium (YGES) organised by the British Geotechnical Association.
