**Ian David Abrahams** (born 15 January 1958) is an English Mathematician, currently

Beyer Professor of Applied Mathematics at the

University of Manchester. He has acted as vice president, and as of January 2008 is president, of the

Institute of Mathematics and its Applications.

## Education

Born in

Manchester, Abrahams was the son of Harry Abrahams and of Leila Abrahams.

He completed his

BSc in

aeronautical engineering in 1979 and

PhD (and

DIC) in

applied mathematics in 1982, both at

Imperial College London. There he won two scholarships and the Finsbury Medal for top undergraduate. For his PhD he was supervised by Frank Leppington for a thesis entitled

*The scattering of sound by ﬁnite thin elastic plates and cavities*.

In thesame year, he moved to Manchester on a 1-year contract. This was the beginning of a collaboration with

GR Wickham. First, they developed some general techniques for solving matrix

Wiener–Hopf problems and this gave the solution to a basic problem of

diffraction theory, namely, scattering by two parallel, semi-inﬁnite, staggered plates. Motivated by the problems of

austenitic steel welds, they went on to developed a theory for wave propagation in certain inhomogeneous anisotropic solids. They also gave asymptotic solutions for scattering by small defects in an elastic half-space making...
