Prof.dr.ir. C.G. (Caspar) Chorus
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 150+ scholars who study and design socio-technical systems, by combing insights from Engineering and the Social and Behavioral Sciences.
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 choice behavior. This opens the door to quantitative insights (e.g. how do people trade off different attributes of choice options?) and predictions (e.g. what will be the market share of a new product or service?), making choice modeling a key method in research fields as diverse as transport, health, marketing, and sociology.
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 or that embed the preferences and values of a society.
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. Funded by highly selective Veni- and Vidi-grant from the Netherlands Science Organization (NWO), my colleagues 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 preferences, heuristics and considerations that humans employ in morally sensitive situations. This work is funded by means of an ERC-Consolidator grant. Besides offering a new perspective for theoretical and empirical choice analysis, this also holds the potential to develop specific types of artificial morality for AI. See http://behave.tbm.tudelft.nl for more information about this research program.
Much of my work finds a fruitful application domain in the field of Transportation. I have a special interest in modeling and predicting traveler behavior, particularly in the context of new transport technologies such as automated driving and electric vehicles. In addition, in recent years I have become increasingly interested in (Public) Health choices. In addition, I am interested and experienced in studying and modeling choice behavior in various other domains, such as Environmental studies, Political Sciences, Marketing, Sociology, Law, etc.
Recently, I have co-founded a company called Councyl. This TU Delft-spin-off help experts in making better decisions, and making them more efficiently. Using choice analysis techniques, we codify expert knowledge into explainable and easy to use AI. Want to more about how we 'scale judgment'? Visit www.councyl.ai.

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.
