Bonnie Cundill


I joined the Clinical Trials Research Unit (CTRU) as Principal Statistician in 2014, following positions as a Lecturer in Medical Statistics and Epidemiology at LSHTM and Statistical Officer at the Department of Health. I obtained a BSc. (Hons) in Mathematics & Statistics from the University of Glasgow in 2001 and an MSc in Medical Statistics from the London School of Hygiene and Tropical Medicine (LSHTM) in 2005.

As the statistical lead for the elderly care portfolio within the Complex Interventions Division (CID) at CTRU I play a key role in the strategy of the portfolio, development of grant applications, statistical oversight of the trials within the portfolio, and mentorship and development of trial statisticians.  I sit on various external trial oversight committees as an independent statistician, act as an expert reviewer for the national research funding body National Institute of Health Research (NIHR), and statistical referee for leading medical journals.

Research interests

With over 15 years' experience as a statistician within health research my main interests lie in the design, conduct, evaluation and reporting of complex interventions, particularly those involving cluster randomised trials.   I have worked on a range of research projects in various contexts from large scale Phase III trials focusing on improving access and targeting of malaria treatment in resource-poor settings through to feasibility studies aimed at improving quality of life for older people.  I also have experience of the design of process evaluations, including methods for maximising, measuring and monitoring intervention fidelity.

I am a co-applicant on a number of research grants held within the portfolio and currently provide statstical oversight for trials within the stroke portfolio.  These include:

  • A phase III multi-centre individual randomised trial with clustering in one arm, investigating extended rehabilitation for older people with frailty after acute illness or injury (HERO)
  • A programme of research including a cluster randomised feasibility trial and large scale definitive Phase III trial evaluating personalised care planning to improve quality of life for older people with frailty (PROSPER)
  • A programme development grant for a novel system of care targetting risk factors for five manifestations of frailty to maintain the independence of older people in hospital and postdischarge
  • A cluster randomised feasibility trial to inform a definitive trial evaluating the effect of posture and mobility training for staff in care homes (PATCH)
  • A cluster randomised feasibility trial for an intervention aimed at improvement physical activity amongst care home residents (REACH)
  • A phase III multi-centre individual randomised trial with clustering in one arm, investigating improved rehabilitation services for helping people return to work following a stroke (RETAKE) 
  • A phase III multi-centre cluster randomised trial evaluating an intervention to improving the safety and continuity of medicines management at care transitions for cardiology patients (ISCOMAT)

Within a background as the lead statistician for an international research consortium conducting complex clinical trials focusing on intervention strategies to inform international health policy and practice, I am also co-investigator for the Global Health Research Group for Surgical Technologies at the University of Leeds.
