Since the mid 1980s, I've worked in university and industrial research, as a manager and editor in technology and environment for an international NGO, and held senior business development, strategy, and procurement posts in industry. I hold a PhD in chemical engineering from Birmingham University, an MBA from Warwick University Business School, and an MSc in Science Communication from Imperial College. In 2008, I left industry to focus full-time on my passion for science and technology, and to share that enthusiasm with others as a freelance science communicator. I live in London with my American wife Erin.
