Suzie Cro is a Research Fellow at Imperial Clinical Trials Unit (ICTU), School of Public Health.

She has a broad range of experience in the design and analysis of clinical trials and other interventional studies. Currently she is the statistician on a variety of clinical trials including; APRICOT - a two-staged randomised placebo controlled trial with an adaptive element for treatment of Pustular Psoriasis with the IL-1 receptor antagonist anakinra; and ASCOT – a randomised controlled trial of adjunctive intraocular and periocular steroid (triamcinolone acetonide) versus standard treatment in eyes undergoing vitreoretinal surgery for open globe trauma. She is also the statistician on a systematic review and individual participant data meta-analysis of skin care interventions for the prevention of eczema and food allergy (SCiPAD).

She is an Associate Editor of the journal Trials and reviews articles for various other journals. She serves as a member of IDMCs and TSCs. 

Her statistical research interests include relevant accessible methods for:

- Handling missing data in randomised controlled trials

- Accounting for post-randomisation events, such as rescue medication and non-compliance in randomised controlled trials

- Transparency in the statistical analysis of clinical trials

Suzie obtained a BSc in Mathematics with statistics in 2008 and an MSc in Statistics with applications in medicine in 2010 from the University of Southampton. Following this she joined the MRC Clinical Trials Unit at UCL as a statistician, where she worked in collaboration with the Royal National Orthopaedic Hospital on a variety of musculoskeletal trials and other research projects. In 2013, alongside her position at the MRC CTU at UCL, she joined the London School of Hygiene and Tropical Medicine to undertake a PhD supervised by Professor James Carpenter. After completing her thesis on sensitivity analysis for randomised controlled trials with missing data, she joined Imperial College in October 2016.
