Two-Year Postdoctoral Research Associate Position Available

A two-year postdoctoral position in fluid mechanics is available to start in October 2017. Please get in touch if you are interested. Full details can be found here.

I am broadly interested in the study of continuum mechanics, principally fluid and solid mechanics, with application to both biological and physical phenomena. Many complex fluid, solid and fluid-solid interaction problems occur naturally in the human body; for example, the veins in the arm collapse when raised above the level of the heart. Fluid-structure interaction is also important in pathologies of the body. The collapse and occlusion of the airways in the lung is driven by an interplay between the elastic properties of the airway wall and the surface tension of the lung-lining fluid.

The behaviour of the coupled continuum systems can be described by nonlinear differential equations, which must be often be solved numerically. After discretisation, the model consists of a large (up to tens of millions for three-dimensional problems) number of coupled equations. Since 2004, Matthias Heil and I (and many students, postdocs and colleagues ) have been developing oomph-lib, an object-oriented library of C++ functions designed specifically to make it "easy" to formulate and solve multi-physics problems. One of the main design aims of the library is to allow calculation of steady and unsteady solutions and their stability, including bifurcation detection and tracking, without a change in problem formulation.

Research Interests:

I am interested in all aspects of fluid and solid mechanics and particularly coupled or multi-physics problems. Much of my work is motivated by biological fluid mechanics, over a variety of scales from millimetric (blood flow in large arteries, airway reopening and collapse) to microscopic (flow on cellular lengthscales, swimming of micro-organisms). I have spent a lot of time in recent years studying interfacial flows and instabilities particularly instabilities induced by geometric changes that may be a consequence of the presence of elastic boundaries. Typically, I take a combined experimental and theoretical approach to solve physical problems, but my particular expertise is in numerical methods. I have a fondness for finite, spectral and boundary element methods, as well as expertise in parallel computation and object-oriented scientific computing.
