Meet the Team

The Environment Network is run by a volunteer steering group who support the network by collating content, finding funding, facilitating meetings and advocating around raising awareness of the role the environment plays in transmission of infection at strategic and policy meetings.

The steering group is made up of academic, industry and healthcare professionals, from all levels of seniority, in order to represent the network membership. We are an open and collaborative group who would always welcome new input and membership, so if you want to get involved get in touch.

Dr Claire Walker

Senior Lecturer

Dr Claire Walker is a registered clinical scientist in immunology and senior lecturer in biomedical sciences. Claire has worked at several major teaching hospitals in the UK including Great Ormond Street Hospital where she completed her PhD in immunology and genetics in collaboration with University College London Great Ormond Street Institute of Child Health.
