About Me

Hi 👋 I’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

• creator of popular open-source packages, like BERTopic, PolyFuzz, and KeyBERT
• written articles on Medium that collectively have be read more than 1,000,000 times
• created the 9 distance measures visualization that often goes viral ^{1, 2, 3, 4, 5, 6, 7, 8}
• frequently give talks about subjects ranging from AI to Psychology
• graduated with three MSc degrees cum laude
• sometimes write academic articles about my open-source work
• published my thesis at ECML-PKDD 2019
• love playing board games (currently Splendor Duel)

Experience

Currently, I work as a Clinical Data Scientist at IKNL in R&D with a focus on NLP-based 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.
