Exposing cockroaches to light can make them pessimistic, while the scent of conspecifics probably makes them optimistic: https://www.biorxiv.org/content/10.64898/2025.12.01.691180v1

In this pre-print Adam Guilfoyle and I showed that cockroaches likely possess affective states, demonstrating cognitive complexity not previously expected and further expanding the case for considering the welfare of invertebrates

Just posting again, but I've got two PhD positions on offer through the CROCUS-DLA at the University of Reading. One on the phylogenetics and evolution of dragonflies with Dr Jamie Thompson, and another on the evolution of gastropods (Polystira) in response to changing climate with Prof Chris Venditti and Dr Jon Todd (NHM UK).

CR2026_43 – Crocus DLA

Really enjoyed giving a talk to the Insect Welfare Research Society this week, and the chance to talk about our work on whether cockroaches feel pain, have positive or negative mental states, and if tagging them influences their behaviour.

And luckily you can watch it back if are looking to while away your Friday: https://youtu.be/wiG4RsEyraQ?si=38TVsx8c9GZLn0FR

Really enjoyed the opportunity to give a talk for the Frontiers in Social Evolution seminar series. My talk, "How and When Social Interactions Alter Evolution", was recorded and is available to watch back here: https://lnkd.in/eKCM5-xh

I talk about past work on North American red squirrels, New Zealand giraffe weevils, cockroaches, and dolphins! 🤓

Trying to measure exploration is the lab is tricky as we aren't always sure we are capturing activity, neophilia, or something else! Our 2 measures of exploration were not correlated suggesting either high within-individual variability or we were indeed measuring 2 different things.
New paper on cockroach behaviour: social network metrics are correlated within groups of 10, but these do not correlate with either a lone or group measure of exploration: https://link.springer.com/article/10.1007/s10164-025-00870-8
Cockroach social network position does not influence exploration tendency
