Welcome to our research group. Our interests lie in a broad range of fluid dynamical challenges from water purification strategies to the manufacture of glass for computer tablet screens. Our approach is to use a blend of modelling, asymptotic, and numerical techniques to enable predictions to be made for the behaviour of such physical systems, and in particular, to give insight into their optimal operating strategies.

We collaborate with a range of scientists from many disciplines, as well as industries, to ensure that our models address the key challenges. If you are interested in joining us or would like to collaborate with us then just get in touch.

Our group


Ian Griffiths is a Royal Society University Research Fellow, EPSRC Fellow and Senior Research Fellow at the Mathematical Institute at the University of Oxford. He is a Fellow of Mansfield College and a College Lecturer at Christ Church. He spends part of each year in Princeton University as a Visiting Scholar and a Visiting Lecturer where he lectures Math Alive, a course in the Department of Mathematics demonstrating the importance of mathematics in everyday life. He also has a collaborative network with Howard Stone and the Complex Fluids Group at Princeton, and the Laboratory of Fields, Flows, and Interfaces at Ryerson University in Toronto. Ian has been a postdoctoral research associate in both the Complex Fluids Group, Princeton, and in OCCAM at Oxford, and completed his doctorate in Oxford in glass tube manufacture.





Armin Krupp is a second-year D.Phil. student working on developing models to understand and optimize the behaviour of water filters. He works alongside our industrial partner Peter Levison from the filtration company Pall Corporation, and is co-supervised by Colin Please. Armin spends some time in Portsmouth and New York where two of the Pall Corporation research centres are based.






Doireann O'Kiely is a third-year D.Phil. student who is working on understanding the physical processes that take place when glass sheets are drawn from a furnace. These glass sheets can be made into a range of high-quality goods such as computer tablet screens. Doireann collaborates with Ulrich Lange from Schott AG and spends some time each year working at their base in Mainz, Germany. Doireann is co-supervised by Chris Breward and Peter Howell.






Sourav Mondal is a postdoctoral researcher who works on an array of challenges in membrane filtration and water purification. He is also working with Maria Bruna and the LoFFI.









Caoimhe Rooney is our blenders expert. She is developing mathematical models that predict how to make the best smoothie, in collaboration with SharkNinja. She is co-supervised by Colin Please.






Mylene Wang is a summer student visiting us from ENSTA ParisTech. She is working on understanding and modelling blocking of membranes in cross-flow filtration and is co-supervised by Sourav Mondal.











Yiliu Wang is a summer student working on species transport in microfluidic flows and is co-supervised by Sourav Mondal.














Past members



Maria Crespo Moya is a Ph.D. student from the Complutense University of Madrid who worked with us for the summers of 2015 and 2016. Her research interests lie in bioremediation for water cleaning processes. In Oxford she worked on liquid crystal microfluidics and was co-supervised by Apala Majumdar.






Lewis Gaul was our undergraduate expert in cycling science. He developed models that predicted how to make the best use of your energy when cycling.










James Herterich completed his D.Phil. in 2015 on developing mathematical models for new water purification techniques. James' expertise lies in asymptotic analysis. He was co-supervised by Dominic Vella in Mathematics and Robert Field and Nick Hankins in Engineering Science to ensure his models capture the important engineering design requirements. James is now a postdoctoral research associate in University College Dublin.






Mo Dalwadi was a postdoctoral researcher from 2014-2015 and worked on developing mathematical models for the flow of particles through inhomogeneous porous media, with specific application to filtration. Mo has expertise in homogenization theory and asymptotic analysis. The project he worked on was through 2020 Science and he was co-supervised by Maria Bruna. Mo is now a postdoctoral researcher at the University of Nottingham.





Almut Eisentraeger was a postdoctoral researcher in our group from 2012-2014. Here she worked on developing mathematical models for water purification using magnetic separation. Almut's expertise lies in numerical computation and she was co-supervised by Dominic Vella. Her research was in collaboration with the Laboratory of Fields, Flows, and Interfaces at Ryerson University, who conducts complementary experiments on lab-scale devices. Almut now works in ITWM.
