Ash is a Research Fellow in the Diabetes Research Centre at the University of Leicester. He works across several areas of interest primarily focused on ethnic minority health, and diversity and inclusion in health research. He has worked on randomised controlled trials, systematic reviews, and qualitative process evaluations.
Ash sits on the editorial board of BMC Public Health, and is guest editing a Special Issue focused on 'Racism as a public health crisis'.

Throughout the Coronavirus pandemic Ash contributed to Covid-19 related research and policy recommendations. Ash is a member of the National Long Covid Research Working Group led by Professor Kamlesh Khunti.

Prior to joining Leicester in 2019 Ash worked at the School of Sport, Exercise and Health Sciences at Loughborough University, and The School of Medicine Pharmacy and Health at Durham University. His initial training was in Physical Activity and Public Health.


Ash has a range of research interests that largely relate to applied public health research. These areas include ethnic minority health and inclusion and diversity in health research.

Ash currently leads an NIHR ARC-EM project on the representation of under-served groups in applied health research. He has received funding as a co-investigator from a variety of funders. Recent examples from 2020 onward include:
