I received my PhD in 2015 from the Department of Developmental and Comparative Psychology at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. My thesis, supervised by Professor Michael Tomasello, investigated the concept of fairness and distributive justice in early childhood. Following this, I took up a Postdoctoral researcher position within the same department, studying the specific circumstances that lead to children’s early sharing behaviour. Before I joined Christ Church I worked as Lecturer in Developmental Psychology at the University of Kent, Canterbury.
My main research interests remain in the development of prosocial behaviour in early childhood. I strive to understand humans' unique “ultra” socialness and the behavioural consequences by investigating their ontogenetic onsets, their developmental trajectories, underlying mechanisms as well as their implications for our modern day society. I conduct my research working mainly with children between two and nine years of age, but also have experience working with infants, adults and chimpanzees. In addition to my broad expertise in developing, conducting and analysing behavioral studies with children, I also possess skills in data collection via EEG and eye-tracking technology, as well as interview surveys.
Research and knowledge exchange
My most current research project assesses the influence of partner characteristics (e.g. competence, age, friendliness) in early social interactions.
Teaching and subject expertise
This year I am teaching on the modules Social and Developing Self (Level 4, also convenor), Social and Developmental Psychology (Level 5) Developmental Psychology (Level 7, also convenor) and Learning and Development (Level 7). I will also supervise a variety of final year projects.
