My research interest is in developing models and methods for multi-modal metropolitan passenger transport systems by combining advancements in behavioral sciences, operations research and complex network theory.

I am co-directing the Smart Public Transport Lab at Delft University of Technology (TU Delft), The Netherlands where I am appointed as an Associate Professor in the Department of Transport and Planning. I am the PI of an European Research Grant called CriticalMaaS and a co-director of the CiTy AI Lab. In addition, I work as a part-time researcher at the Royal Institute of Technology (KTH), Stockholm Sweden.

Interested in more information? Have some ideas or suggestions?

Get in touch and drop me an email on o.cats@(please-remove-this-part)tudelft.nl

In this blog you can find information on my scientific publications, student theses that I (co-)supervise or have advised, BusMezzo a dynamic public transport operations and assignment simulation model that I have developed, information on the development and implementation of real-time control strategies and the occasional updates.

My research activities focus on system dynamics and uncertainty in route choice and assignment, service optimization, control, network design and robustness, travel information and reliability. These activities often support transport agencies and operators’ decision making.

I am the Editor-in-Chief of the European Journal of Transport and Infrastructure Research (EJTIR). I am also a member of the Editorial Board of  Transportation, Journal of Transport Geography, Journal of Public Transportation and Journal of Urban Rail Transit.
