Stein Fekkes studied Applied Physics at the Fontys academy in Eindhoven. He did his graduation project at the Clinical Physics Laboratory at the department of Paediatrics of the Radboud university medical center, where he worked on myocardial lateral strain estimation using ultrasound. After receiving his bachelor's degree in 2004, he continued with the master Medical Engineering at the Eindhoven University of Technology (TU/e). In 2007 he did an internship at the Princess Margaret Hospital in Toronto, Canada where he developed an interstitial fluid pressure measurement analysis tool for cervix tumours. In 2009 he receives his master's degree with 4D dose accumulation using non-rigid deformation models, a graduation project performed at the Maastro Clinic in Maastricht. After almost 4.5 years of work in industry he decided to become PhD student as of November 2013 on the VICI project entitled “Ultrafast 3D Ultrasound Imaging: the next level for cardiovascular diagnosis”.
