Andy and I worked closely to develop taught MSc courses and programmes within the institute. He was always supportive, encouraging and exceptionally enthusiastic. If I ever needed somebody to bounce ideas off or to give me advice, his door was always open. Together, we were developing a new online Cancer Biology MSc to start in 2022. It has been very difficult going forward without his experience, enthusiasm and support. I hope that we can dedicate a session on the programme to his name, as I know he was very keen to use his experience as a teaching tool. He is truly missed.
