Kim Thomas

Professor of Applied Dermatology Research & Co-Director of the Centre of Evidence Based Dermatology, Faculty of Medicine & Health Sciences



Kim joined the Centre as a Research Fellow in 1999, with responsibility for developing and conducting clinical trials at the Centre. She then went on to co-ordinate development of the UK Dermatology Clinical Trials Network, which was formally established in 2002. Since this time, Kim has conducted many independently-funded clinical trials to evaluate interventions for the treatment and prevention of skin disease. These trials cover a range of skin conditions including eczema, cellulitis, vitiligo, verrucae, acne and rare skin diseases. She was promoted to Professor of Applied Dermatology Research at the University of Nottingham in August 2013, and is now Co-Director of the Centre of Evidence Based Dermatology. Kim's particular interests are in the design and conduct of dermatology clinical trials, and in clinical trial methodology (especially outcomes research and diagnostic testing). She is a founder member of the UK Dermatology Clinical Trials Network, is a member of the Executive Committee for the international Harmonizing Outcome Measures for Eczema (HOME) initiative, and a member of the Cochrane Skin Group Core Outcome Set Initiative (CSG-COUSIN) methods group. Kim was Co-Director of Research for the School of Medicine from March 2018 to Feb 2021.
