Biography

Professional biography

After working for MSD, I started a PhD entitled 'Enhanced Prediction and Prevention of Torsades de Pointes' at Maastricht University as part of a collaboration with Astrazeneca. I was then a post-doctoral researcher at K.U. Leuven in the laboratory of Prof. Karin Sipido, and obtained my own FWO funding. 

I carried out additional postdocs in the lab of Prof. Gelsomino at Maastricht University in the Department of Cardiothoracic surgery, where I focussed on novel assist devices and atrial fibrillation, and at the University of Birmingham in the groups of Dr Davor Pavlovic and Prof Paulus Kirchhof focussing on the electrophysiology and treatment of atrial fibrillation.

I joined the Open University in January 2020 as a lecturer where i am building up my own research line focussed on both atrial and ventricular arrhythmogenesis and utiling electrophysiological and imaging techniques

Please feel free to get in touch with me if you are thinking about applying for a PhD via the ILESLA scheme (Welcome | ILESLA - Interdisciplinary Life and Environmental Science Landscape Award)
