Paul worked at Anthony Nolan for three years as our medical officer and completed a very successful MD (Res) related to post-transplant immunity and vaccination. This work has had a positive and lasting impact on how transplant patients are treated and led to him working with us more recently to generate invaluable vaccination guidelines for our patients during the pandemic. Paul was such a kind, thoughtful, intelligent and wonderful human being whose passion for improving outcomes for our patients always shone through. We will miss his insight and collaborative spirit enormously, his smile and his compassion. He was much loved at Anthony Nolan and will be deeply missed. Our thoughts are with Lukxmi, his family and all who knew and loved him.
