Honoured to receive a Poster Prize at #BAP2026 for my project investigating the Effects of Transcranial Ultrasound Stimulation (TUS) on Interoceptive Attention. I'm grateful to everyone who worked on this project, @camillanord.bsky.social and Veronica Forslund, who were at the conference, and...

Does problematic social media use involve the same dopamine-related reward mechanisms as addiction? That’s the question motivating the research I presented at the @bapsych.bsky.social Summer Meeting, involving a dopaminergic manipulation to probe the involved mechanisms. #BAP2026

Excited to be chairing/presenting at our post-doc symposium discussing the advancements (and challenges 🤫) of computational psychiatry with a ⭐️ line-up of @saramehrhof.bsky.social @yanivabir.bsky.social & Alicia Rybicki. If at #BAP2026, come join us today at 2pm ‼️

🎉 Now published in Nature Communications! 🧠 We develop a novel computational reinforcement learning & habit model of Twitter data, and show that younger people & women are more behaviourally sensitive to 'Likes'. Read the paper: bit.ly/4f1vsKS

🚨 Does social media use show established neurocognitive signatures of addiction? Concerns about social media addiction are widespread, yet whether platforms' design features actually engage the same neurocognitive pathways as established addictions has remained untested. doi.org/10.31234/osf...

🚨New Preprint Announcement🚨 Social Media Reward Sensitivity and Depressive Symptoms Over Time 🧵 Social media platforms are designed to maximise engagement by amplifying social rewards such as “likes”, and there is widespread concern that these digital designs contribute to mental health declines.

1/ "Silicon samples" are becoming more and more common in research and polling. One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want. The updated version of this preprint is now online! THREAD🧵 arxiv.org/abs/2509.13397

This smells distinctly like collider bias and/or selection bias and/or regression to the mean... You simply can't select teen prodigies, and world class athletes rom databases, and go run regressions without serious consideration of the selection process!

This article provides more data showing how easy it is to manipulate humans on social media. These researchers rerouted the algorithm on Twitter to push some users toward “antidemocratic attitudes and partisan animosity”. It only took 1 week to elicit changes that used to take 3 years.
