    Holly graduated in Mathematics with Statistics (University of Southampton) in 1996, obtained an MSc in Statistics with Applications in Medicine (University of Southampton) in 1997 and in the same year joined the MRC Environmental Epidemiology Unit as statistician for the Hertfordshire Cohort Study.

    In 2013 Holly completed a PhD which described social inequalities in musculoskeletal ageing among community dwelling older people in the UK.

    Holly is currently the principal statistician for Prof Avan Aihie Sayer’s research programme which aims to identify lifecourse influences on healthy ageing. Holly is line manager for two junior statisticians and provides mentoring and technical support for other statisticians in the MRC LEU.

    Holly’s main research interests include (i) the usefulness of grip strength as a single marker of frailty in older people and the association between levels and loss of grip strength in later life and subsequent morbidity and mortality, (ii) the trajectory of grip strength across the life course, (iii) the operationalisation of consensus definitions of sarcopenia to identify prevalence of sarcopenia among community dwelling older adults and (iv) linkage of the Hertfordshire Cohort Study database with routinely collected Hospital Episode Statistics data and the application of appropriate complex survival analysis techniques to analyse the resulting multiple-failure survival dataset.
