My undergraduate thesis, "Distinct patterns of social contagion under risk and ambiguity", is now published online at @commspsychol.nature.com Deeply grateful for the guidance and constant support of Dr. Qingtian Mi, Prof. Jian Li, and Prof. Lusha Zhu.

New Annual Review with @nathanieldaw.bsky.social: “Planning in the Brain: It's Not What You Think It Is.” We argue that the brain's 'planning' machinery is mostly used for learning from simulated experience, and that thinking prospectively at decision time is just one special case of this process.

Excited that my paper on metacontrol in humans and neural networks with @summerfieldlab.bsky.social and @lhuntneuro.bsky.social is out in PNAS! We examine the way that predictive representations of control enable behavioral adaptation across settings, and pathologies: www.pnas.org/doi/10.1073/...

Our work on how neural circuits in the cerebellum encode prior probabilities led by Julius Koppen is out now in Nature Neuroscience www.nature.com/articles/s41... Big thanks to Julius Koppen & the whole team! And dedicated to all of us who found inspiration in Bayesian theories of the brain!

🔔PREPRINT: Sleep ripples drive single-neuron reactivation for human memory consolidation 1/9: How does sleep support human memory consolidation? To test this, we recorded hundreds of neurons in the human medial temporal lobe (MTL) across learning, wakefulness, and sleep. doi.org/10.64898/202...

Using non-invasive ultrasonic neuromodulation to boost threat extinction. Finally able to causally unravel amygdala computations in healthy humans. I’ve been dreaming about these capabilities for years and it still feels magical. Pinch me, I can hardly believe how strong these effects are.

Check out our new preprint! We directly tested a common assumption in neuroimaging: Is resting-state the best estimate of intrinsic organization? Spoiler: Across datasets and brain systems, multi-task fMRI did better. 👇

We review studies showing that when brain areas face similar computational demands in social and non-social context, they perform the same computations. We argue that exaptation (repurposing of traits for new functions) played a key role in brain evolution.

Amazing work.

Exciting research position in Germany (Freiburg) with Carsten Mehring uni-freiburg.de/en/job/00004.... Carsten was my PhD supervisor. He is of the best scientists I have seen.

🚨Friends, we’re happy to share that our book is available for pre-order! 🎉 We aimed to cover all the foundations of the topic in an accessible manner for a large audience. It could help set up a bachelor-level curriculum on the topic. Pre-orders are very key for the fate of books: shorturl.at/Dxbif

Happy to share my new paper published in @nathumbehav.nature.com: A critical look at statistical power in computational modeling studies, particularly those based on model selection. www.nature.com/articles/s41...

Come find out all about cognitive maps in the PFC!!

How do we decide to reach out and make friends? My PhD work on this question is out today in @pnas.org 🎉 Study done in collaboration with the incredible @mirunarascu.bsky.social, @sorcha-hamilton.bsky.social, Ingrid Yu, and my two amazing supervisors, Matthew Rushworth and @mkflugge.bsky.social👇

New paper our in @pnas.org, lead by @isabellehoxha.bsky.social with Léo Sperber. We use evolutionary simulation to assess and compare the adaptive value of positivity bias and gradual perseveration in reinforcement learning. Follow the thread below (and Isabelle!) for more details!

I’m glad to have played a small part in this project, where the brilliant Deng Pan combined modelling, fMRI and ultrasound stimulation to demonstrate the causal role of the hippocampus in learning based on inference. See Deng's thread below

We are super excited about the first human transcranial ultrasound study from our lab which is now on BiorXiv, showing the amygdala‘s role in processing ambiguous emotions and showing TUS changed resting-state connectivity and metabolite concentrations (GABA) in the amygdala - a huge team effort! 🥳🙏🏼

New paper with @nathanieldaw.bsky.social in Nature Communications: an RL model that builds a successor map compositionally. The new model plans as well as the best models, and it links components of the map used for planning to neural codes in the medial entorhinal cortex. rdcu.be/eAofi

New paper from our lab now in @nature.com . We show that our brains use basis functions or "building blocks" to navigate social interactions. Rather than tracking every individual separately, social information is compressed into patterns that can be flexibly combined. www.nature.com/articles/s41...

Chris Summerfield's previous book (Natural General Intelligence) was a spectacular read! Looking forward to reading his new book: These Strange New Minds.
