About Louisa Ells

Dr Louisa Ells joined the University in May 2012 as Reader in Public Health and Obesity. She is a member of the Department of Women’s, Children’s and Public Health, and co-leads the digital and creative economy grand challenge. She is also a specialist advisor to Public Health England, an invited expert for the NICE Centre for Guidelines, and sits on the European Association for the Study of Obesity Nutrition working group.

Louisa has specialised in obesity research for the past two decades, working across academia, policy and practice, having previously worked at the North East Public Health Observatory and was a founding member of the National Obesity Observatory (now part of Public Health England). Louisa runs an applied research group at Teesside, finding research solutions to address real world problems. She has a particular interest in co-production, undertaking systematic reviews and service evaluations, and developing digital and creative tools to support weight management and public health. She has worked on projects with a combined income exceeding £1million, and has a strong publication record and established network of international collaborations spanning Europe, USA and Australia.
