It is with deep regret that we announce the death of our colleague Dr David Wails, senior principal scientist at Johnson Matthey, a valued partner in the MACBETH project. David’s research focused on catalysis and in particular on cleaner energy applications. He was an excellent scientist and will be deeply missed. David lost his life in the tragic events in Reading, England on 20 June 2020. We extend our sincere condolences to his family, friends and colleagues.
