Ian Griffiths. I am a Royal Society University Research Fellow, EPSRC Fellow and Senior Research Fellow at the Mathematical Institute at the University of Oxford. I am a Visiting Fellow of Mansfield College. I spend part of each year in Princeton University as a Visiting Scholar and a Visiting Lecturer where I lecture Math Alive, a course in the Department of Mathematics demonstrating the importance of mathematics in everyday life. I also have 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. Prior to my current position I was a postdoctoral research associate in the Complex Fluids Group, Princeton, and in OCCAM at Oxford. I completed my doctorate in Oxford in glass tube manufacture.

## Our group

Graham Baird is one of our postdoctoral researchers and is working on global challenges concerning the removal of arsenic from water, with particular application to India.

Kris Kiradjiev is a first-year D.Phil. student as part of the InFoMM CDT working with polymer and textile company Gore, working on developing mathematical models for purification processes. Kris is co-supervised by Chris Breward.

Armin Krupp is a final-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.

Christiana Mavroyiakoumou is an MSc student developing mathematical models that predict how to make microstructured glass optical fibres, which are used in the communications industry for data transfer. To understand this problem she is studying how a complex network of connected viscous sheets evolve with time. Christiana is also working with Peter Howell on this project.

When you move the two ends of an elastic strip together you observe buckling. But what happens if you do the same to a viscous strip? If you move the ends slowly then the viscous strip will remain straight and just thicken. But move them fast enough and the viscous strip exhibits similar behaviour to an elastica. Ousmane Kodio is our second-year D.Phil. student whose job it is to understand the analogies between elastic and hydrodynamic instabilities, to understand how wrinkles form. Ousmane is co-supervised by Dominic Vella.

Michael McPhail is a D.Phil. student on the InFoMM CDT. Michael is working on a mathematical model that predicts how to make different shaped Cheerios. His work is in collaboration with Nestle.

Galina Printsypar is one of our postdoctoral researchers, and she works in collaboration with Dyson trying to improve filter performance in vacuum cleaners. Galina is co-supervised by Maria Bruna.

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. He was a finalist in the IChemE Young Chemical Engineer in Research Award 2016 . You can see his entry video here. Click here for Sourav's departmental page.

Raka Mondal is a postdoctoral researcher who is working on Mathematical modelling of contaminant percolation through soil beds in India. This project is in collaboration with Sirshendu De based in IIT Kharagpur.

Abir Boualaoui is a visiting student from Paris ENSTA. She is developing models to describe compression in filtration processes and supporting her results with experiments that she is conducting in the Mathematical Institute's experimental observatory. Abir is also working with Armin Krupp and Finn Box.

Florian Charlet is a visiting student from Paris ENSTA and is studying and contrasting the Leslie-Ericksen and Beris-Edwards models for nematic liquid crystals. He is co-supervised by Apala Majumdar.

Maria Crespo Moya is a frequent visiting researcher to our group. She completed her Ph.D. in the Complutense University of Madrid and is now based in the University of Montpellier. Her research interests lie in bioremediation for water cleaning processes. In Oxford she works on liquid crystal microfluidics along with visitor Apala Majumdar.
