Research Programs


Woutjan Branderhorst obtained a MSc degree in Computer Science from the Eindhoven University of Technology. He performed his graduation project in the Biomedical Engineering department, where he worked on machine learning techniques for automatic MRI-based atherosclerotic plaque classification. In 2011 he finished his PhD thesis "Focused multi-pinhole SPECT" at the University Medical Center Utrecht (Image Sciences Institute), under supervision of prof. Freek Beekman and prof. Max Viergever. He then continued to work as a post-doctoral fellow at the Academic Medical Center Amsterdam, where he worked with prof. Kees Grimbergen and prof. Ard den Heeten on the development and validation of pressure-guided mammography. Part of this work was performed as a visiting researcher at Volpara Solutions (New Zealand). In May 2018, he returned to the UMC Utrecht to work in the group of prof. Hugo de Jong at the department of Radiology and Nuclear Medicine.

Woutjan's current research interests are the development and application of simultaneous PET/MRI, and the application of machine learning techniques in radiology and nuclear medicine.
