BSc, MSc
OCTRU Medical Statistician
I joined the Oxford Clinical Trials Research Unit (OCTRU) as a medical statistician in May 2023. My job involves contributing to the design, conduct, analysis and presentation of results of collaborative clinical research projects, with a focus on randomised clinical trials. I am currently working on a range of trials related to orthopaedics, including SPELL, ODDSOCKS, WHITE10-LIT and WHITE13-DECI.
I obtained an MSc in Medical Statistics from the University of Leicester in 2022. My dissertation involved modelling the growth trajectories of fetuses using multilevel models and then using various cluster analysis methods to explore ways in which the growth trajectories could be classified. I completed my undergraduate degree in Mathematics, also at the University of Leicester. My final year project focused on design and data issues related to the interpretation of ANCOVA models.
