Dr Steve Walker PhD MRCP(UK) DTM&H

Associate Professor


I am a Consultant Dermatologist and Associate Professor in the Department of Clinical Research. I trained in dermatology at Glasgow, London and Manchester in the United Kingdom and at Harvard University in the USA. I completed my PhD thesis: "The measurement, treatment and immunopathology of leprosy Type 1 reactions" under the supervision of Professor Diana Lockwood at LSHTM.
I work as a consultant dermatologist in the United Kingdom seeing NHS patients with a wide range of skin disorders.
My main research interests are the pathophysiology and managment of leprosy reactions, cutaneous infection, scabies and other ectoparasitic skin disorders and the epidemiology of skin disease.




I teach on a variety of LSHTM courses both MSc and the Diplomas in Tropical Medicine and Hygiene.
I also lecture students studying for the MSc in Clinical Dermatology at King's College London and the MSc in International Health at the Charité - Universitätsmedizin Berlin.


I am the coordinator of the Erythema Nodosum Leprosum International STudy (ENLIST) Group. Erythema nodosum leprosum (ENL) is a severe complication of leprosy. We are clinicians, statisticians and laboratory scientists with extensive clinical and research experience in the diagnosis and management of leprosy and its complications.
We are based at institutions in seven countries on four continents. The group is coordinated from London and includes centres in Bangladesh, Brazil, Ethiopia, India, Indonesia, Nepal and the Philippines. The ENLIST Group aims to improve: the understanding of the mechanisms which cause ENL, the evidence to guide treatment decisions and the access to effective treatments.
I am also the co-PI on a study of scabies outbreaks in UK residential care facilities. This study is a collaboration with researchers from the Brighton and Sussex Medical School and Public Health England.
