In the early phase of my career, my research interests focused on clinical applications of Interventional Paediatric Cardiology. After completion of specialist training my research interests focused on the development of new interventional treatments for congenital heart disease as well as the use of MRI imaging and hybrid X-Ray / MRI guided catheterisations. This materialised through a clinical training Fellowship in Interventional MRI that I was awarded in 2007 by King’s College London Biomedical Research Centre / Guy’s & St Thomas’ NHS Trust. Our research work involved the development and pre-clinical assessment of a novel MR-compatible fiberglass guidewire, that led to the world first-in-man MRI guided congenital interventions trial. The animal experiments for the pre-clinical trial were performed in mini-pigs and took place in Aachen, Germany and Aarhus, Denmark. I was actively involved in the percutaneous interventions in the swine and the MR-guided catheterisations in the animals.

The research led to my MD Thesis awarded in 2013.

My most recent research interests consist of research topics based on comparison of echocardiographic and MRI methods for diagnosing and managing congenital heart disease.
