I have only known Andy for a year and had the privilege to be his student for a short amount of time, but it was quite clear from day one, that he was the friendliest, kindest most supportive supervisor I could ask for. His work, his virtues and his vision, all live within me and I'll be forever grateful for all he offered to both me and the rest of the world. I would like to express my condolences and deliver mine and my family's deepest wishes to Jane, Helena and Robert.
