Personal profile
Biography
I am a Pure Mathematician. After studying mathematics and physics at Heidelberg I did my doctorate at Imperial College under the supervision of Oliver Pretzel.
I work in algebraic combinatorics, finite permutation group theory and applications in finite geometry and reconstruction theory.
Follow this link for details of current PhD opportunities in Mathematics. But feel free to email me to discuss projects outside these areas and alternative sources of funding.
