Greg was a valued colleague during my time at OCSLD where a number of us shared the same ‘basement’ office space at Wheatley. When I arrived at Brookes, and new to the UK, Greg was very supportive. He helped me to settle in as he understood the issues faced by those who move from living and working in the south of the world to the north. Greg was always encouraging and helped promote the introduction of some of the new work I was then able to do at Brookes and elsewhere. I will always be grateful for his warmth and the good advice he always gave me.
