Ned Hartfiel


In 2009, Ned completed his MSc at Bangor University in Public Health and Health Promotion.   For his master’s thesis, Ned conducted a randomised controlled trial investigating the effect of yoga for improving wellbeing and resilience to stress in the workplace.   The results of this trial were published in the Scandinavian Journal of Work, Environment and Health (April 2010), where it was the journal’s top-viewed article for five months in row.

In March 2010, the Welsh Assembly Government awarded Bangor University (academic partner) and Dru UK (company partner) a two year KTP project, in which Ned was selected as the Project Associate.  Under the supervision of Dr Christopher Burton, Ned conducted another pilot study examining the effect of a yoga-based programme for reducing stress and back pain in the workplace.  The results of this trial were presented at the Symposium of Yoga Research in the September 2011, and submitted for publication in March 2012.

In March 2012, Ned began his PhD at the Centre for Health Economics and Medicines Evaluation (CHEME) under the supervision of Professor Rhiannon Tudor Edwards. Building on his two previous pilot studies, Ned conducted a larger randomised controlled trial to investigate the cost-effectiveness of a yoga-based intervention for reducing back pain and sickness absence in the workplace.  The results of this trial are currently in press and illustrated in the following video produced by the CADARN Project:

Since completing his PhD thesis in 2016, Ned was awarded a graduate entrepreneur visa to enable him to deliver yoga-based ‘healthy back’ programmes to employees in a wide variety of settings throughout the UK.  In addition, Ned continues to work at CHEME as a research officer, specialising in social return on investment analysis.
