Biography

Personal webpage: http://www.maths.gla.ac.uk/~pstewart

I am currently a Professor of Applied Mathematics in the School of Mathematics and Statistics, University of Glasgow. My research focuses on applying continuum mechanics to solve interesting physiological or industrially motivated problems. Before coming to Glasgow, I held Postdoctoral Research Associate positions at the University of Oxford (2011-13) and Northwestern University (2010-2011). I completed my PhD in 2010 from the University of Nottingham, where my thesis was entitled Flows in flexible channels and airways.

Research interests

My research interests lie in the application of continuum mechanics to physiological and industrial problems. In particular I am interested in problems involving interaction between a fluid flow and deformable interfaces, such as liquid-gas free surfaces and elastic solids.

My current research focuses on several topics:

1) Mathematical modelling of the human eye, with a particular interest in retinal blood flow and retinal haemorrhage;

2) The dynamics of gas-liquid foams, with particular application to understanding fracture in crystalling materials and production of high-porosity metallic solids (solid metal foams) as lightweight materials;

3) Mathematical modelling of cell cytoskeleton, with particular application to understanding cell response to mechanical cues;

4) Flow through flexible-walled vessels in the human body, with application to the onset of self-excited oscillations.
