Graham was always there for my life, philosophy, and mathematics questions, and a great collaborator with projects too. Kind, funny, and great at bad poetry. Graham will be missed. ~Janelle Wiley

I was just here to make a donation in tribute to Graham, even though it still doesn't feel real. It had me sitting here thinking how much I miss him and then straight away I smiled, remembering he'd always say you only missed me because your aim was so bad :-) I'll never know how he managed to remember so many awful jokes and puns to keep us smiling. So quick-witted despite the brain fog. He once told me that when you make a special connection with someone that they're never really gone. Graham certainly did that with many people and I hope he knew just how much his unwavering support over the last 14 years or so has meant to me and the whole family. He'll never be gone from our hearts and minds x

From all at Invest in ME Research - we just want to say how much we admired Graham’s work and his achievements which helped all people with ME. His modest manner in providing intelligent commentary endeared him to all. He was a lovely man. This is a very sad time and we send our condolences to his family. They should know how greatly respected Graham was and how much he will be missed by so many people.
