In addition to his research at TPM, Chorus taught several courses and developed a strong track record as a supervisor for MSc and PhD-candidates. He was presented with several teaching and PhD supervision awards. And while he may have stepped away from his role as a teacher, his passion for education remains.

Professor Chorus’ research expertise lies in mathematical modelling of choice behaviour. He focuses on modelling human decision making, with a special interest in finding mathematical representations of non-rational choice behaviour and morally sensitive decision making.

Chorus incorporates elements of design into his research, as sound and empirically validated mathematical models of human decision-making are invaluable for designing better and more human-centred policies, products, and services.

These models, when framed differently, can also help people make better decisions. In a research-through-design process, Chorus’ team explored the use of decision support models by professionals, and the effect they may have on human agency and autonomy.

This latter line of research inspired the creation of TU Delft spin-off company, Councyl. This company, co-founded by Professor Chorus, designs self-learning decision support software for professional organisations, based on choice models.
