Happy to contribute to this project!! Thanks to @GiuliaZanni and the great team. Take a look at our paper👇

Our new paper is out! Altered loss learning across fast and slow time scales in problem gambling @ColumbiaPsych jneurosci.org/content/45/1/e…

Thrilled to announce our lab has received the Notice of Award for our first @NIMHgov R01! 🎉 We'll be tackling anhedonia in schizophrenia using computational psychiatry. Huge thanks to our incredible lab members and collaborators🙌 @ColumbiaPsych @ColumbiaMed

🚨A new preprint! If you are curious about reward/punishment anticipation in psychiatry and computational mechanisms, we have something for you. Please take a look! Thanks to @kyo_iigaya @IAitsahalia Krishan and Toby, happy to be part of this team. osf.io/preprints/osf/…

@Harry_Costello @UCL_ICN @UCLPsychiatry You missed one of the Mondays

During my PhD I took daily pictures of #QueenSquare from my @UCL_ICN office window. Excited to start a new chapter today as Clinical Lecturer @UCLPsychiatry. I hope my desk view is as good…

@Harry_Costello @foltynie @valvoon @jonroiser @ProfRobHoward @wellcometrust Congrats Harry!!🎉🎉

Delighted to successfully defend my PhD today! Special thanks to my examiners @foltynie @valvoon who made the viva really enjoyable, the supervisor superteam @jonroiser @ProfRobHoward, my brilliant colleagues, the patients who made my research possible & @wellcometrust (for💰).

Today I'm very happy to share our recent work, with @spk3lly and @neuromurphy! We show that centroparietal EEG signals track momentary belief updates rather than an integrated decision variable across samples in a discrete token, volatile environment task biorxiv.org/content/10.110…

Finally published!! “Bayesian at heart ♥️: Towards autonomic outflow estimation via generative state-space modelling of heart-rate dynamics” Estimating HR as a hidden process whose properties can be estimated via Bayesian methods sciencedirect.com/science/articl…

Finally published! A friendly introduction and comprehensive overview of how information decomposition deepens our understanding of the brain 👇🏽👇🏽

Thrilled to share our new @NatureNeuro article, where we tracked 110 first-time mothers & 34 control women to isolate the brain changes associated w/ pregnancy, childbirth, and postpartum shorturl.at/lEGLO @DiePaternina @MagdaMartinezGa @dmartindeblas @susanna_carmona🧵👇

How can we believe something different than what we perceive? Happy to share our work on this with @GuillermoHorga ,@marianne_brkr and Florian Ragalmuto, now out in @NatureComms : nature.com/articles/s4146…

Glad to see this review with @Anne_On_Tweet @ccnlab (and my artwork!) being featured on the cover of the @TrendsCognSci December issue. The illustration is meant to convey the idea that "goals" shape cognition doi.org/10.1016/j.tics…

📢Paper alert 📢very happy to share our latest work, published in @Brain1878: “Neural basis of speech and grammar symptoms in non-fluent variant primary progressive aphasia spectrum” doi.org/10.1093/brain/… @AlbaLanguage @UCSFmac @InvestigaUDD @NeurologiaUdeC @Ciencia_UdeC

The notion that goals are central to human cognition is intuitive, yet learning and decision-making researchers have often overlooked the topic. In this @TrendsCognSci article, @Anne_On_Tw and I propose it’s time to start studying goals in their own right authors.elsevier.com/a/1hjzw4sIRvPN…

Very excited to share our work with Emeline and @GuillermoHorga now published in @SfNJournals: jneurosci.org/content/43/29/…

The value we place on an option depends on the context and available alternatives. But why does getting $1 when the possibilities were 0 or 1 feel much better than when the possibilities were 1 or 10? 🧵👇 1/7

Very excited to share recently published findings of my PhD work! Many thanks to our collaborators and all authors! #responsivepolymers #neuroinflammation #nanomaterials #drugdelivery — pubs.acs.org/doi/10.1021/ac…
