Key administrative duties
I led the team developing a new undergraduate degree BSc in Mathematics at the University of Salford, developing the modules and programme structure, based on applied mathematics for the workplace, and guiding it through the internal approvals procedure.

I am the programme leader for the mathematics undergraduate degree at Salford.

I lead the mathematics outreach team, planning and delivering material on UCAS and general open days, visits to local schools and colleges, and enrichment days developing programme `maths at work'.

I have been awarded many grants several in conjunction with the IMA (Institute of Mathematics and its Applications) for novel teaching delivery particularly in relation to employer engagement.

Research Interests

My work is on the fundamental mathematical description of fluid mechanics, and notable achievements are the revision to the Batchelor vortex which has incorrect symmetry, and a revision to Lighthill's slender body theory which evaluates the lift force incorrectly.

These theoretical developments are published mainly in a series of papers in Proc. R. Soc. A, and have resulted in a new vortex description as well as a new slender body theory which has been verified experimentally by myself from an EPSRC grant, and this experimental verification has been published in J. Fluid Mech.

Qualifications and Memberships


PhD in Applied Mathematics, University of Manchester, 1992.
BSc Hons Degree in Mathematics and Physics, University of Manchester, 1988


Fellow of the Institute of Mathematics and its Applications (FIMA)


Of the 41 publications, 21 are published in prestigious rigorous peer-reviewed journals, and are highlighted by a bold double asterix **n followed by their order number n and appended to the reference. Of these, 7 are single author, a further 8 joint author, and a total of 16 I am the lead author.

I have published in all the recognised top journals in my field, for example Proc. R. Soc. A, J. Fluid Mech., SIAM J. Appl. Math., Fluid Dyn. Res., Phys. Fluids, ZAMP, Proc. Math. Sci. I have applied these theories to the vortex decay behind the Airbus A380 in J. Aerospace Engineering, and also applied fluid dynamics techniques to provide an explanation to the behaviour of the Jabulani world cup football in Mathematics Today, IMA.  I have also published in other fields, for example on Finite Element techniques for short wave diffraction/scattering problems published in Int. Jour. Numer. Meth. Engng., on an innovative parallelisation technique for Global Climate Models in Parallel Computing, and on a structural analysis problem associated with innovative telescope design published in Wide-Field Spectroscopy, Experimental Astronomy, Astrophysics and Space Science Library, and Proceedings- SPIE the International Society for Optical Engineering. I have also published in mathematics educational research journals such as MSOR Connections and BSRLM Informal Proceedings.
