My research interests have been in computational number theory,
the arithmetic of elliptic curves,
algebraic combinatorics and public-key cryptography.
My current personal research is on Carmichael numbers and
pseudoprimes.
I am a member of the
London Mathematical Society;
a Fellow
of the Institute of Mathematics and its
Applications and a
Chartered Mathematician and
Chartered Scientist.
My Erdos number is 3 (Pinch --
Swinnerton-Dyer
-- Davenport
-- Erdos).
