In 1994, he won a Wellcome Trust clinical epidemiology training fellowship and did an MSc in Clinical Epidemiology at the London School of Hygiene and Tropical Medicine.

Hywel chaired the National Research Development Support Unit Network from 2004 to 2006. He founded and then directed the University of Nottingham Clinical Trials Support Unit which has since led many major new NIHR trials and which is now fully registered with the UKCRC.
Hywel has also had a passion for research commissioning and he chaired the Research for Patient Benefit Programme for East Midlands from 2006 to 2009. Hywel was appointed Chair of the HTA Commissioning Board and became Deputy Director of the HTA Programme in January 2010. He was also national chair of the NIHR CCRN Dermatology Specialty Group (2008 to May 2014).

Hywel's main research interests are evidence-based dermatology and the epidemiology and treatment of childhood eczema.
In terms of academic impact, Hywel has published over 640 peer-reviewed articles, including papers in Nature, the NEJM, Lancet and BMJ, and three books. He is the second most cited dermatology researcher in the world on Google Scholar (131,513 citations December 2022) with a H-index of 122 and i10-index of 466. His lifetime c-score for 2022 (excluding self-citations) places him in the top 1.3% of the top 100,000 scientists worldwide, the most cited scientist in the Faculty of Medicine at Nottingham and the second most cited scientist in the University of Nottingham. The c-score (Mendeley Data, V5, doi: 10.17632/btchxktzyw.5) focuses on impact (citations) rather than productivity (number of publications) and it also incorporates information on co-authorship and author positions (single, first, last author).
Hywel has raised over £10m in non-commercial externally funded research into health technology assessment in relation to skin disease in the last 10 years as lead applicant.
Hywel "retired and returned" in March 2022 meaning that he now works two whole days a week (Tuesday and Wednesday) for the University and clinical work on Thursday mornings for Nottingham University Hospitals NHS Trust (mainly doing advice and guidance for paediatric dermatology as an honorary consultant paediatric dermatologist).
