Giovanna is a Research Officer in Pharmacoeconomics at the Centre for Health Economics and Medicine Evaluation with a background in research methods and statistics. Previous to this post Giovanna worked as a researcher for Manchester City Council. She holds a MSc in Research Methods and Statistics from the University of Manchester and a MA degree in International Development: poverty, conflict and reconstruction from the University of Manchester. She is a trained quantitative researcher, with a particular focus on modelling large dataset to conduct statistical analysis by applying multi-level models and social network analysis.
Giovanna joined CHEME in 2015 and is currently working on several projects:
- The use of Ferrous Iron salts in primary care in the UK (IHAT). This is a retrospective cross sectional study which will provide the health economics of iron treatment in the UK.
- The British Antibiotic & Silver Impregnated Catheters for ventriculoperitoneal Shunts (BASICS). BASICS is a three-arm, double-blind multi-centre randomised controlled trial which will compare three ventriculoperitoneal shunts in patients with hydrocephalus.
- Radiation versus Observation following surgical resection of Atypical Meningioma (the ROAM trial). ROAM is a two-arm, multicentre European randomised controlled trial for patients who have undergone surgical resection of grade II meningioma.
- A Randomised Controlled Trial of the Clinical Effectiveness, Safety and Cost Effectiveness of Adalimumab in Combination with MethOtRExate for the Treatment of Juvenile Idiopathic Arthritis Associated Uveitis (SYCAMORE). SYCAMORE is a double blind, multicentre randomised controlled trial for patients with juvenile idiopathic arthritis associated uveitis.
Giovanna is undertaking a PhD in Pharmacoeconomics as a staff candidate. Her thesis will explore the applicability of different statistical methods (frequentist approach versus Bayesian) for trial based cost effectiveness analyses. Her PhD is funded by MRC (Medical Research Council) and is supervised by Professor Dyfrig Hughes (Bangor University) and Prof Nicky Welton (University of Bristol).
