Prof. Andre Dekker, PhD (1974) is a board-certified medical physicist at MAASTRO Clinic, full professor of Clinical Data Science at Maastricht University and head of Academic IT at Maastricht University Medical Center all in Maastricht, The Netherlands. His research focuses on three main themes: -building global data sharing infrastructures; -machine learning cancer outcome prediction models from this data; -applying outcome prediction models to improve lives of cancer patients The main scientific breakthrough of his group has been the development of a Semantic Web and ontology based data sharing and distributed learning infrastructure that does not require data to leave the hospital (Personal Health Train). This has reduced many of the ethical and other barriers to share data. Prof. Dekker has authored over 130 publications in peer reviewed journals covering informatics, imaging, radiotherapy, tissue optics and heart disease and holds multiple awarded patents. He has held visiting scientist appointments at the Christie Hospital NHS trust; University of Sydney Australia; Liverpool and Macarthur Cancer therapy centres Australia; Illawarra Shoalhaven Local Health District Australia; Universita Cattolica Del Sacro Cuore, Italy; Radiation Therapy Oncology Group, USA, Varian Medical Systems, USA and the Princess Margaret Cancer Centre in Canada.
