Biography

I am a leading UK researcher in mathematical and computational modelling of biological
fluid dynamics, and physiology, with expertise including soft tissue mechanics, the
systemic, pulmonary and coronary circulation, and arterial disease. From the 1980’s I led
major developments in the multiscale theory and quantitative experiments on pattern
formation in suspensions of swimming micro-organisms (bioconvection/active
suspensions) which is now a major international research field. Starting in the 1990’s, I
have developed first models of microstructural-based growth of abdominal aortic
aneurysms, flow and pressure waveforms in the pulmonary circulation, flow and wall
mechanics coupling the left ventricle and systematic arteries, to predict biomechanical
buckling of arterial dissections, parameter estimation and uncertainty quantification for
circulation models, and coupling strain in the gall bladder with pain experienced by
patients.

Research interests

My recent research portfolio is focussed on new and very challenging areas in mathematical
physiology and biological fluid dynamics including:

• A Leverhulme Research Fellowship project on linking blood flow and pressure in
capillary beds to mathematical and computational models of the full circulation.
• A coupled Pulmonary Circulation and Respiration model with application to
ventilation in COVID-19 patients.
• An industrially funded PhD studentship project with a major European vascular
graft manufacturer, Terumo-Aortic (Glasgow), and POLIMI on the design of stents to
minimise the effects of remodelling of the aorta wall post stenting for treatment of arterial
dissection and related diseases.
• Modelling of cell cytoskeleton mechanics with MIT.
• A GSK funded project on the post-myocardial infarction injury in collaboration with
Prof Colin Berry (Cardiology, Glasgow).
• Patient-specific blood flow and pressure in coronary arteries and veins in the
beating heart, allowing for the squeezing of small vessels within the wall during systole.
• Pulmonary hypertension in humans with the Scottish Pulmonary Vascular Unit
and in mice with collaborators in Mathematics at NCSU and Biomedical Engineering at
UC Irvine, including patient-specific statistical parameter estimation.
• Upscaling methods to couple the mechanics of individual cells to tissue scale
biomechanics in the heart and other soft tissue.
