About Me

Hi šŸ‘‹ Iā€™m Maarten!

Over the last few years I have taken, what felt as, a rather unorthodox path towards becoming a Data Scientist. I started out as a Psychologist with master degrees in organizational- and clinical psychology. Although interesting fields on their own, the statistical nature of the fields grabbed me the most. I sought out to combine psychology and statistics with a master degree in Data Science, which eventually led me to being the Data Scientist I am now.

Things to Note


Currently, I work as a Clinical Data Scientist at IKNL in R&D with a focus on NLP and LLM-based (federated) algorithmic solutions in the field of cancer research and palliative care. Aside from my daily work, I write articles on medium and continue the development of open-source packages.
