Fiona was a very kind, highly valued colleague who was always very generous, sharing her immense knowledge and helping others flourish. Our encounters over the last months were over video-conferencing only, but I thoroughly enjoyed engaging with her. Next to exchanging smart ideas, she always had a witty and humerus comment which made working light! We will miss her immensely. Wishing her family and all her friends strength and much love and care for each other. Charles Roehr (Associate Professor, National Perinatal Epidemiology Unit, University of Oxford).
