I am a scientific researcher in machine learning for medical image analysis from the Netherlands.
Say hello at or
I work as a postdoc at the Data Science group of the Radboud University in Nijmegen, the Netherlands, on transfer learning for breast cancer screening. I teach deep learning to MSc students.
Until the end of 2019, I worked as a PhD student and researcher at the Biomedical Imaging Group Rotterdam, part of the Erasmus MC University Medical Center in Rotterdam, the Netherlands.
I work on domain adaptation and feature learning, and their applications in model-based medical image analysis. I am interested in the theoretical and practical aspects of machine learning and computer vision.
Shifting representations — Adventures in cross-modality domain adaptation for medical image analysis.
PhD thesis, Erasmus MC/Erasmus University, Rotterdam, June 2022.
elasticdeform is a Python library for differentiable elastic deformations for N-dimensional images. It works on 2D, 3D and higher-dimensional images as a data augmentation method. It computes gradients for use with TensorFlow or PyTorch.
I was a contributor to Theano when it was still cool.

After a reasonably successful but unfulfilling start as a student of economics and business, I had great fun as a computer science student at the Delft University of Technology. At the end of 2012 I completed my Master of Science in Media and Knowledge Engineering with a thesis on a theoretical aspect of active learning.
In early 2013 I started as a PhD student at the Biomedical Imaging Group Rotterdam, part of the Department of Radiology of the Erasmus MC University Medical Center in Rotterdam, the Netherlands.
I enjoy programming, tinkering with Linux, and web development. During my studies I worked as a freelance web developer, mostly for De Digitale School and Dalton Voorburg.
