I undertook my first degree in Medicine at the University of Leeds, qualifying in 2007, during which time I also completed an intercalated degree in Healthcare Ethics.  I then gained five years of clinical experience working in a variety of medical specialities, which included six months working in Melbourne, Australia.

I carried out a Masters in Physical Activity for Health at Sheffield Hallam University in 2010-12 and upon completion, I joined the Public Health Speciality Registrar Training Programme in the East Midlands.  As part of this training programme, I also undertook a Masters in Public Health, which I completed in 2014.  I passed both my Membership of the Faculty of Public Health exams in 2013.

In 2015/16, I completed a 12-month Academic Public Health Fellowship, which I carried out at ScHARR.  I was able to pause my Public Health Specialty Training at that stage.  During this fellowship, I conducted some further primary research into sedentary behaviours in NHS staff and the use of the flipped classroom in postgraduate medical teaching.  I also spent some time putting together a National Institute for Health Research Doctoral Research Fellowship (NIHR DRF) application, which I was successfully awarded.

I commenced the NIHR DRF in October 2016 at ScHARR and have again paused my Public Health Specialty Training in order to undertake this.  The fellowship is due to finish in September 2019 at which point I will re-join and complete the Public Health Specialty Training scheme of which I have 22 months remaining.

Research Interests

I am particularly interested in the issue of sedentary behaviour in the workplace,  which was a theme I pursued during my dissertation projects for both my Masters degrees and has formed the basis of my NIHR DRF research plan.

I have also previously carried out research looking at sedentary behaviour in NHS staff, the use of the flipped classroom in postgraduate medical education, and methods of reducing length of stay and readmission rates to hospital in older people.

Professional Activities

I am a GMC registered medical professional.

I am also involved in the organisation of the annual Public Health Science Conference.

Current Projects

  • NIHR DRF project: Feasibility of a low-cost, co-produced complex intervention to reduce workplace sitting time in different workplace settings.
  • Study looking into the nature of the associations between obesity and social deprivation.
