LMS joint research group in tropical mathematics
I am an active member and currently the lead organiser of an LMS Joint Research Network in tropical mathematics, consisting of researchers at universities including Manchester, Birmingham, Warwick, Queen Mary University of London and Swansea. I have acted as a local organiser for several of the network's workshops in Manchester and been invited to speak at meetings in Birmingham, Warwick and Swansea. A report of the January 2012 workshop held in Manchester appeared in the LMS newsletter.

Since 2009 I have been an active member of the LMS funded research network North British Semigroups and Applications Network. The group, which consists primarily of researchers at Heriot-Watt, Manchester, St Andrews and York, meets roughly three times a year. I was an invited speaker at both the 4th NBSAN meeting in York (my first encounter in the NBSAN world) and the 8th NBSAN meeting in St Andrews. I also helped with the organisation of the 9th and 11th meetings, which were held in Manchester.

MAGIC Postgraduate Student Conference
I was one of the senior organisers of the MAGIC Postgraduate Student Conference 2009 and the LMS Northern Regional meeting that followed. In particular, I was responsible for designing the scientific programme of both events and timetabling the parallel sessions. The conference, attended by around 120 participants, included plenary lectures from seven leading mathematicians and contributed talks and posters from around 50 students.

Tropical reading group
In 2008 (January-December inclusive) I was the organiser of the Tropical reading group. The main aim of the reading group (which began in 2007, under the direction of Dr Mark Muldoon) is to learn about all aspects of tropical mathematics. Members of the group have included (pure and applied!) mathematicians, computer scientists and biologists. The reading group continues to be a successful venture, and is currently jointly organised by myself and Dr Mark Kambites.

Pure Postgraduate Seminars
In the academic year 2005/2006 I was the organiser of the University of Manchester Pure Postgraduate Seminar Series. These seminars provide an informal environment for postgraduate students in pure mathematics present mathematical ideas. I was also the main organser of the first joint Manchester-Leeds postgraduate seminar day.
