Maurice Kloos, a Medical Engineering student from Rotterdam University of Applied Sciences and ESCH-R intern, recently graduated with a 9 for his research project titled: ‘A Waste Audit of the Erasmus MC Interventional Cardiology Department’.



At the beginning of April, Maurice and Jasper Klasen, ESCH-R PhD student, began working on an ambitious task: mapping the complete material flow within the Interventional Cardiology department.
