Work
Selected projects and tools I have built or worked on. The About page is about my background. This page is about what I have built.
Current projects
- PROTEUS, a framework for simulating exoplanets. My role includes framework engineering, benchmarking, HPC and software quality. I also help shape development practices in the age of AI assistance.
- ALMA Pipeline, the data reduction pipeline for the ALMA radio telescope array. Maintenance work focuses on performance, testing and maintainability. The WSU ALMA upgrade will bring in much more data and we need to prepare the Pipeline for that as well. My role also includes project management for the NOVA team.
- Explainable AI, opening black box ML models. We created DIANNA, a tool for comparing explanation methods for machine learning models in research. I also worked on Distance Explainer, an explanation method for embedding models.
Past projects
- Research software quality at NLeSC. As Technology Lead, I led software quality efforts and oversaw technical choices in many research projects. More details are available on my Research Software Directory page.
- Digital humanities data analysis. I worked on archeology, media, politics, art and language projects using text mining, linked data, point cloud analysis, machine learning and natural language processing.
- Particle physics performance work. I helped speed up comparisons between complex theoretical models and experimental data for CERN/LHC experiments in the RooFit/ROOT package.
- BARCODE, software for Bayesian reconstruction of cosmic density fields.
Vibearium
Small webapps I have built recently, mostly with a lot of AI assistance, and deployed on GitHub Pages.
- Allage adds up the ages of everyone in a group and finds group age anniversaries. Source
- Timezone compare helps plan meetings across time zones. Source
- RSE self-test asks whether you are already a research software engineer and suggests what to do next. Source
- Coalitiestatengeneraal checks possible coalitions for the Dutch parliament, including both chambers. Source
