Willem (27) studied Physics in Amsterdam, after which he participated in the Dutch National Think-tank in 2014. Here he researched in a group of 23 academics of different backgrounds how the Netherlands could be made healthier by using the large amounts of digital information in healthcare. From the think-tank emerged Pacmed, an organisation that utilises Machine Learning to present the expected outcomes for treatments to doctors, based on what worked for similar patients in practice. Next to being director at Pacmed, Willem is a PhD student at the Leiden Medical Center where he researches the value of Machine Learning in healthcare, and under what conditions these technologies should be implemented to be of sustainable value for everyone.
