Philip Aston participated in the Mathematics in Medicine Study Group on 15-17 April in London (the UK MMSG NC3Rs Study Group 2013).  He worked on the project “Modelling heart rate changes in the mouse as a system of delayed, weakly coupled oscillators“.  Details of the research problem can be found here.  According to Philip, “it was an intense few days, but some useful ideas were generated by the group working on this project”.
