## Applied Mathematics

The major research interests of the group are in theoretical and computational fluid mechanics. However, members of the group also undertake research in numerical analysis, structural and solid mechanics, inverse problems and applied analysis. Our research in the area of applied and computational mathematics is informed by problems at the interface with physical sciences, biological sciences and engineering and benefits from interdisciplinary collaborations within Cardiff University and further afield. Our national and international collaborators include research groups at Imperial, Oxford, Cambridge, Warwick, Swansea, Canberra, Curtin (Perth), Perth, Delft, Northwestern, Ljubljana and Montréal.

### Key Research Areas
