The goal of my work is the re-use of routine care data to add value to the healthcare process.

Previously I was at the University Medical Center Utrecht (UMCU) and University Medical Center Groningen (UMCG), where I managed a large database with clinical and laboratory data on kidney transplants. I made this data easily available for other researchers, enriched it with new information, and analyzed and visualized the data to deliver new insights. I also built diagnostic models of auto-immune and auto-inflammatory disorders, using information from the electronic health record extracted with text mining techniques.

Before switching to data science in the medical domain, I was a PhD student in the Cognition and Plasticity lab of Prof. Heleen Slagter, funded by an NWO Research Talent grant. My PhD research focused on improving attention through electrical stimulation of the brain. During my PhD I became a strong supporter of open science principles, and I still strive to make my work as accessible, transparent, and reproducible as possible.
