Ioana Marian

Medical Statistician

I collaborate with researchers on trauma, rehabilitation and cancer randomised controlled trials as part of the Centre for Statistics in Medicine (CSM) and Oxford Clinical Research Trials Unit (OCTRU). I contribute as the trial statistician on UKSTAR, BOOST, and GRASP trials, as well as for WISE and HOPE-E feasibility studies. I am involved in the OPAL cohort study which aims to develop a prognostic tool for mobility in the elderly.

I have been awarded an NIHR pre-doctoral fellowship where I am investigating methods used in factorial design randomised controlled trials.

In my previous role at the University of Southampton, I contributed to the data management, analysis and reporting of PDSAFE, a multi-centre randomised controlled trial aiming to reduce falls in people with Parkinson’s disease.

I completed an MSc in Statistics at the University of Kent in 2015. My research project focused on modelling the spread of an infectious disease and vaccination efficacy using stochastic epidemic modelling. I have experience teaching statistics for business at higher education level and enjoy multi-disciplinary work.

I joined CSM and OCTRU in December 2017.
