Network meetings
I recently co-organised an North British Semigroups and Applications Network meeting in Manchester, together with Alex Levine, Mark Kambites, Dmitry Kudryavtsev and Nóra Szakács.
I was the lead organiser of an LMS Joint Research Network in tropical mathematics --this network is now organised by Ben Smith.

Former PhD students

• Peter Fenner, Some algorithmic problems in monoids of Boolean matrices
• Thomas Aird, Semigroup identities of tropical matrix semigroups
• Alice Clayphan-Taylor, On tropical matrix semigroups
