I'm a scientist & engineer with a PhD in machine learning (ML) and a passion for (combinatorial) optimization.
During my PhD at the University of Amsterdam (supervised by Max Welling), I have published and been an (outstanding) reviewer at top ML conferences, on the topic of machine learning for combinatorial optimization / vehicle routing. I received a best paper honorable mention at ICML 2019 for my work on stochastic beam search and I have been a Research Scientist Intern at Google DeepMind. See Google Scholar for my papers and citations.
At ORTEC, I worked on various ML & optimization projects such as warehousing, load optimization and vehicle routing. I initiated and lead the team that won the 2021 DIMACS VRPTW (Vehicle Routing Problem with Time Windows) challenge and I initiated and organized the EURO Meets NeurIPS 2022 Vehicle Routing Competition with over 150 participants and 50 final submissions.
I have participated in many (ACM-ICPC style) programming and math competitions. While Python is my major tool, I have worked with many languages and I am a quick learner so I can code my way around. I like engineering, to build stuff and I will typically find a way to make things work, aiming for optimal results.

I was the initiator and lead organizer of the EURO Meets NeurIPS 2022 Vehicle Routing Competition which brought together researchers from the Operations Research (OR) and Machine Learning (ML) community to solve a static and dynamic variant of the Vehicle Routing Problem with Time Windows (VRPTW).
SET® Finder is an Android/iOS app that uses TensorFlow to run a Deep Neural Network on-device to find SETs in the SET® card game.
At the SIKS PhD Course “Machine Learning & Optimization”", I have given the overall introduction, a lecture on machine learning & optimization and a practical assignment on vehicle routing.
I regularly give internal trainings at the ORTEC Education Factory on the topics of machine learning, deep (reinforcement) learning and competitive programming.
I have been a Teaching Assistant for Reinforcement Learning 2019 at the University of Amsterdam, for the lab / homework sessions and supervision of group projects. I also gave a guest lecture on Monte Carlo Tree Search and AlphaGo.
I have been a Teaching Assistant for the new Reinforcement Learning 2018 course at University of Amsterdam. I developed the computer labs and supervised homework and lab sessions. Additionally I gave a guest lecture about Monte Carlo Tree Search and AlphaGo.
I have been a Teaching Assistant for the computer labs for Machine Learning 2 in 2018.
