Nick, 

I think I first met you at a conference in honour of your Michael Thompson, your PhD supervisor, you being introduced to me as our new lecturer about to join the University of Bristol from the University of East London. Since then, we interacted many times because of our shared interest in nonlinear dynamical systems theory. I greatly appreciated your positive attitude, and how your Christian conscience drew you to using your engineering knowhow to try to make the world a better place. I am glad we finally got to work together on research with Rory White and the late great John Macdonald. It felt that it was immesurably cruel that just as your research was coming into full fruition through the award of major funding you were struck down with this illness.  But I know that the legacy of your work and attitude will continue for many years to come at the University of Bristol, and beyond.
