After completing his Medical School and Pediatrics residency at the University Hospitals of Geneva and Faculty of Medicine, Switzerland, Dr L’Huillier’s interest in transplant infectious diseases and clinical virology motivated a 2-years fellowship in Pediatric Infectious Diseases at the Hospital for Sick Children, Toronto (Canada) where he gained clinical and research experience in the field. He then completed another 2-years research fellowship in Transplant Infectious Diseases at the University Health Network in Toronto, focusing on transplant virology. Since July 2019, he has been appointed as a Junior Faculty in Geneva University Hospitals’ Pediatric Infectious Diseases Unit where he continues to focus on clinical care and research projects in pediatric virology

Dr. Langley is a pediatric infectious disease physician in the Department of Pediatrics and is cross-appointed in the Department of Community Health and Epidemiology in the Faculty of Medicine. She is based at the IWK Health Centre and the Canadian Center for Vaccinology. She conducts studies on the prevention of infectious diseases using vaccines, from phase 1 (first in humans) through to efficacy trials (phase 3) and post-marketing studies of how well vaccines work when they are used in immunization programs (phase 4). These studies are done with collaborators in public health, industry, universities, and non-governmental organizations. Dr. Langley has a particular interest in prevention of respiratory infections such as Respiratory Syncytial Virus and influenza. Her work also focuses on vaccine policy and evidence-based decision making in immunization programs.

I am a second-year medical student at the University of Calgary in Canada. I was previously a pediatric nurse and this research project is one I started last summer while doing data surveillance as a research nurse. I am happy to be a part of ESPID and to learn more about pediatric infectious disease from the various experts.

I am a Clinical Lecturer in Paediatrics at the University of Oxford and a PIID GRID trainee. I completed an ACF at the University of Liverpool during my first 3 years of Paediatric training. Following this, I undertook a PhD looking at the interactions of Salmonellae with the human host, in the form of hiPSC-derived gut organoids and macrophages at the Wellcome Trust Sanger Institute / University of Cambridge. I have been at the University of Oxford since 2020, where I plan to continue my work on Salmonellae, and complete my GRID training.
