In experimental studies, a preference for collaboration emerges early in child development and is considered a cornerstone of socio-cognitive development. In our recent study in published in JEP:G we challenge this assumption: psycnet.apa.org/fulltext/202...

Happy to share a short article I wrote for @theconversation.com , where I highlight our recently published EVApeCognition Dataset (www.nature.com/articles/s41...) and discuss how it can help advance research into great ape cognition and behaviour theconversation.com/great-apes-w...

Great apes: what we know about their cognition, cooperation and curiosity after two decades of research

A database of great ape research promises to unlock deeper understanding of their cognition, intelligence and social behaviour.

Not a secret anymore! I am extremely proud and happy to present you the EVApeCognition Dataset, out now in Scientific Data. Over the last 5 years we have assembled and standardized data from 150 studies on great ape cognition from the WKPRC in the Leipzig Zoo! www.nature.com/articles/s41...

Thank you so much tor inviting me to represent @manyprimates.bsky.social at #ehbea2026. A bit intimidating but very enjoyable to give my first talk as network co-coordinator.

Great panel discussion on team science and big datasets in comparative cognition at #ehbea2026

I'll only join virtually and miss out on beautiful Leiden, but if you're at @ehbea2026.bsky.social do join our symposium on Thursday afternoon and chat about big data and big team science. Looking forward to it and to representing @manybabies.org

⏳ Blink, and you’ll miss it… Registration for #EHBEA2026 closes tomorrow (1 April) 🗓️ Your final chance to be part of four days of ideas, debate & discovery in Leiden 🇳🇱🧠🌷 Be there—or hear about it later 😉 👉 www.ehbea2026.com

PhD Opportunity working with @shona-d.bsky.social and me on the development of children’s collaborative problem-solving skills. This is an Academic Associate position (PhD + teaching) for 4 years. Full details here: jobs.yorksj.ac.uk/vacancy.aspx.... Please get in touch with any queries.

Glad to share our new study led by @kirstensutherland.bsky.social. We have investigated how chimpanzees solve common pool resources using a novel group paradigm. Find more in Kirsten's post

Excited to share this work done with @alex-primate.bsky.social and Daniel Haun @mpi-eva-leipzig.bsky.social (the first publication from my PhD!), where we found that chimpanzees sustained a collective resource for longer in groups of four compared to dyads rdcu.be/e0qPR

Chimpanzees are better at solving resource dilemmas in larger, more tolerant groups. Cooperation & tolerant leadership matter.
