I am an assistant professor at the Econometric Institute of the Erasmus University Rotterdam. My research focuses on delay management, dispatching, and disruption management in railways. For my Ph.D. thesis, I have developed several extensions of the classical delay management model. After my graduation, I have been working on online delay management and integrated disruption management within the European project ON-TIME. At the moment, I focus on optmization in public transportation in general. Some of the project I am or have been working on are described below.

Together with Thomas Breugem and Dennis Huisman, I am working on railway crew planning. We are currently incorporating fairness aspects in the traditional crew rostering approaches. Together with Rowan Hoogervorst and Dennis Huisman, I am working on rolling stock rescheduling. In particular, we are incorporating delays and adding rescheduling flexibility into existing approaches.

Lukas Bach, a Ph.D. student at Aarhus University, has visited Erasmus University Rotterdam several times since April 2013. Together with Lukas and Dennis Huisman, I work on the integration of train timetabling, engine routing and crew scheduling for a real-world case of DB Schenker, Rail Scandinavia. By allowing for some flexibility in the timetale, the overall costs of the timetable and crew schedule could be reduced by 6-8 percent. A paper on this research has been accepted for publication in Transportation Science.

I have collaborated with some of my former fellow PhD students. Together with Willem van Jaarsveld, I have looked into an algorithm to solve multi-item inventory problems. We have written a paper on this project that has been accepted for publication in Omega. Together with Lanah Evers, I have been working on robust solutions to the orienteering problem. Our paper on this research is published in a special issue of Annals of Operations Research. Together with Kristiaan Glorie and Theresia van Essen, I have studied the Tray Optimization Problem (TOP). Here, sterile intruments must be grouped into nets and are then assigned to surgeries. A paper on this research is published in European Journal of Operational Research.

When I was a Ph.D. student, I have worked part-time on crew scheduling at Netherlands Railways (NS). In cooperation with SISCOG, we have developed an algorithm that can tackle the crew scheduling problem for a whole week at once. One of the main results is a crew scheduling algorithm that can solve complete week instances both for drivers and for guards. A paper on this algorithm has been published in Public Transport.
