Dr Paul Griffiths

MSci in Mathematical Engineering PhD in Applied Mathematics

Lecturer in Engineering and Mathematics (Collaborative Provision)

Summary

Dr Griffiths holds an MSci in Mathematical Engineering and a PhD in Applied Mathematics from the University of Birmingham. His current research focuses on boundary-layer stability and transition. He is particularly interested in the effect non-Newtonian fluids have on the onset of instability in boundary-layer flows. This research work is practically relevant to numerous industrial applications.

Paul is part of a fluid mechanics research group that consists of academics and PhD students working at the University of Leicester (UK), Manchester Metropolitan University (UK) and The University of Sydney (AUS). As part of this ongoing international collaboration Paul will be visiting The University of Sydney in January 2017.

Paul joined the Department of Mechanical Engineering and Mathematical Sciences in August 2016. Alongside his teaching and research duties Paul is also the department’s Associate College Partner Liaison Manager.

Teaching

This year Paul is the module lead for the second year BEng/MEng module ‘Engineering Mathematics and Modelling II’ (U04530). He has previously taught courses on ‘Mathematics with Computation’ and ‘Computer-Based Modelling’.

Supervision

Paul is currently co-supervising three PhD students working within the Thermofluids research group at the University of Leicester. He has supervised numerous BEng dissertations and is always interested to hear from potential PhD candidates.
