Welcome to my webpage. I am professor of choice behavior modeling, and head of the Engineering Systems and Services department. The ESS-department consists of 120+ scholars who study and design transport, energy and information systems as well as their integration, by combing insights from engineering, the social sciences and humanities.

Summary of my research and teaching profile (a recent CV can be found here):

Life is a series of choices, great and small.

Choice behavior models provide a mathematically rigorous and empirically testable understanding of choices. This opens the door to quantitative insights and predictions concerning human choice behavior, making choice behavior models a key methodology in research fields as diverse as transport, energy, health, sociology, and marketing.

Intriguingly, because they are so rigorously formalized, choice models also offer the potential to equip artificial intelligence with decision systems that generate human-like behavior.

As a professor of choice behavior modeling, my research aim is to develop and empirically validate models of human decision-making that combine high levels of behavioral realism and mathematical tractability. In recent years, funded by prestigious Veni (2010) and Vidi (2012) grants from NWO, my co-workers and I have developed choice models based on bounded rationality, including the now widely used random regret minimization model suite.

Most of my current work is focused on designing moral choice models, which capture the heuristics and considerations that humans employ in morally sensitive situations. This work is funded by means of an ERC-Consolidator grant, and should ultimately lead to a specific, 'human' type of artificial morality for AI. See behave.tbm.tudelft.nl for more information about this research program.

As head of the Engineering Systems and Services department, much of my work finds its application domains in transport, energy and ICT (AI). I have a special interest in modeling and predicting traveler behavior, particularly in the context of new transport technologies such as automated driving, electric vehicles, and mobility-as-a-service. However, I also study and model choice behavior in various other domains, such as Environmental studies, Health, Political Sciences, Marketing, Sociology, Law, etc.

New discrete choice theory for understanding moral decision making behavior
In 2017, my team and I have started a five year long research effort which aims to develop and empirically validate new mathematical (discrete choice and agent based) models for moral decision making. This research endeavor is funded by a 2 million euro ERC Consolidator grant.
