Ioana Marian
MSc
OCTRU Senior Medical Statistician
I collaborate with researchers on trauma, rehabilitation and cancer randomised controlled trials (RCTs). I help design, set-up, monitor, analyse and disseminate RCTs in a large portfolio (UKSTAR, BOOST, GRASP, TRANSLATE, DRAFT3-CASP, REACH, WISE, ITAD) as well as feasibility studies (HOPE-E, INTACT, MMoST, TEMPO). I train and support other trial statisticians on the team.
In 2024 I was awarded the "Doug Altman Award for Statistical Excellence".
I have been awarded an NIHR pre-doctoral fellowship where I am investigating methods used in factorial design RCTs.
In my previous role at the University of Southampton, I contributed to the data management, analysis and reporting of PDSAFE, a multi-centre RCT 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 Centre for Statistics in Medicine (CSM) and Oxford Clinical Research Trials Unit (OCTRU) as a medical statistician in December 2017.
