Christopher Riddell is a postdoctoral researcher at the Child Development and Education Research Institute at the University of Amsterdam. Broadly, his work focuses on socio-emotional development across the lifespan. He is interested in how children and infants express their own and understand others' emotions. Additionally, he examines how emotional signals - such as facial expressions, body language, and changes in physiology - inform the choices we make on a daily basis: such as who we find likeable and trustworthy. To understand these processes better, he hs recently begun to examine emotions in cross-cultural and cross-species contexts. Chris takes an integrative approach to his research: combining physiological data with expert facial expression coding, behavioural economic paradigms, and advanced statistics. He is passionate about open science and ensuring the results of his work reach a wide audience, having made a number of media appearances, including at NEMO Kennislink, Radio Sleutelstad, VRT Radio 1, and Het Klokhuis.
