MR SHAUN ISHERWOOD

Biography

I am from the Northwest of England.

My undergraduate MMATH was at The University of York.  I focused on algebra and analysis, and my dissertation was on inverse semigroups and inductive groupoids.  Then I went on to do an MPhil in Mathematics, undertaken at the University of Essex; my supervisor was Prof. Gerald Williams, and together we worked on cyclically presented groups of positive word length four.

My research is on a function called Δ (capital delta), defined as the maximum diameter of the Cayley graph of a group with respect to finite normally generating sets.  The project was advertised by the University of Aberdeen as, "Groups, Subgroups, and Boundedness"; here is a quote from one advertisement:

"In recent years some powerful geometric techniques were introduced to prove results about algebraic groups and related mathematical objects such as lattices.  The aim of this project is to investigate new applications of these techniques to the structure of algebraic groups and the spaces that they act on."

It looks like I will focus on SL(n,q) and other finite groups of Lie type.  My supervisor is Prof. Benjamin Martin.

You can find me on Mathematics Stack Exchange.

External Memberships

I am a member of the London Mathematical Society and the Edinburgh Mathematical Society.

Prizes and Awards

In the Summer of 2014, I was granted funding and a stipend for a three month undergraduate research project at The University of York in an area of semigroup theory.

My MPhil was funded by a departmental scholarship, including living expenses.
