He currently holds a number of research grants for the study of heart muscle disease with Tissue Doppler and the use of contrast microbubbles for detecting myocardial perfusion and inflammation. He is devoted to teaching both, under-graduate and post-graduate medical students and is an invited lecturer and visiting Professor in several universities around the world.

He has published more that 300 full papers in peer review journals, more than 400 abstracts, more than 20 book chapters and two books on non-invasive imaging of myocardial ischaemia and Echocardiography.
