Biography

Read more on my personal website, or you can contact me at doireann.okiely@ul.ie.

I am an applied mathematician, working on the mathematical modelling of physical systems. My work focuses mostly on fluid mechanics and elasticity, but I am also interested in chemical reactions, heat flow and other physical processes.

During my PhD, I studied the production of thin glass sheets via the redraw process in collaboration with Schott AG. Since then, I have become interested in the deformation of thin elastic sheets, and the intricate wrinkled patterns that can be found on them under the right conditions. Broadly speaking, I am interested in fluid-structure interactions, viscous flow, capillarity, elastocapillarity, moving boundary problems, elasticity and heat flow.

Research Interests

I am an applied mathematician. I use maths - usually differential equations - to describe, understand and predict the behaviour of physical systems. My specialties are systems involving fluid flow, systems involving deformation of solid bodies, and systems involving chemical reactions. I am motivated by real-world problems, by situations where counter-intuitive behaviour can be explained using maths, and by taking phenomena that are usually annoying and using them to our advantage.

You can find details of some of my research projects on my research page. Here is a list of the areas I work or have worked in:

Fluid Mechanics:
Viscous flow, capillary flows, fluid-structure interaction

Solid Mechanics: Elasticity, plasticity, wrinkle mechanics

Chemistry: Decontamination problems, batteries

Industrial mathematics: Glass manufacture, metal forming
