Thank you for the support you have given me over the years. Doing great science  was fun, and I learned a lot from you.  I will always remember the tutorial you gave me on ab initio calculations at a Graphene Flagship meeting over a beer. But beyond this, you taught me so much and helped me get through the non-scientific parts of academic life at UCL. You are such a character, and made me laugh a lot – thanks. What you have done for your team over the years is incredible – your people always do so well and your legacy will go on and on.
