We’re recruiting a postdoctoral fellow to join our team! 🎉

I’m happy to share that I’ve opened back up the search for this position (it was temporarily closed due to funding uncertainty).

See lab page and doc below for details!

infant data from experiment 1

conceptual schema for different habituation models

results from experiment 2 with adults

Ever wonder how habituation works? Here's our attempt to understand:

A stimulus-computable rational model of visual habituation in infants and adults doi.org/10.7554/eLif...

This is the thesis of two wonderful students: @anjiecao.bsky.social @galraz.bsky.social, w/ @rebeccasaxe.bsky.social

🚨New paper out w/ @gershbrain.bsky.social & @fierycushman.bsky.social from my time @Harvard!

Humans are capable of sophisticated theory of mind, but when do we use it?

We formalize & document a new cognitive shortcut: belief neglect — inferring others' preferences, as if their beliefs are correct🧵

Flyer for the event!

🚨New preprint with my stellar student Junsong

A Small-World Mind Theory of social cognition doi.org/10.31234/osf...

Big network, close connection🤯

It explains why low-dimensional findings dominate & high-dimensional evidence emerges

Naturalistic designs matter to understanding the complex mind

Can self supervised learning help understand how the brain learns to see the world?

Our latest study, led by Josephine Raugel (FAIR, ENS), is now out:

Social inference brain networks in autistic adults during movie-viewing: functional specialization and heterogeneity - Molecular Autism Background Difficulty in social inferences is a core feature in autism spectrum disorders (ASD). On the behavioral level, it remains unclear whether reasoning about others’ mental states (Theory of Mi...

❗New Paper Alert ❗

We found some (but overall weak) evidence for greater differential responses in brain networks underlying theory of mind inferences than those involved in empathic responses in autism. #neuroskyence #autism #openaccess

So cool to see our project, spearheaded by Igor Bascandziev, featured in Harvard's 'Usable Knowledge'!

Investigating action topography in visual cortex and deep artificial neural networks High-level visual cortex contains category-selective areas embedded within larger-scale topographic maps like animacy and real-world size. Here, we propose action as a key organizing factor shaping vi...

New preprint out! We propose that action is a key dimension shaping the topographic organization of object categories in lateral occipitotemporal cortex (LOTC)—and test whether standard and topographic neural networks capture this pattern. A thread:

continuum of inductive potential from low (relatively minimal categories whose members are dissimilar) to high (coherent meaningful categories whose members are similar) above a cartoon child. an icon of a tiger appears under "high" inductive potential, with "closes eyes when happy" appearing as a feature of a tiger in a zoo, with an arrow pointing to the tiger icon, and a dashed arrow extending it to a tiger on a savanna. an icon of a pedestrian appears under "low" inductive potential, with "closes eyes when happy" appearing as a feature of a woman on a street, with Xs over arrows pointing to the pedestrian icon, and to a different pedestrian.

📣 new paper! people use some categories to generalize (e.g., we generalize something we learn about one tiger 🐯 to other tigers 🐅), but not others (e.g., we don't generalize from one pedestrian 🚶 to other pedestrians 🚶‍♂️). how do people learn what categories allow for generalization? 🧵

Our perception isn't a perfect mirror of the world. It's often biased by our expectations and beliefs. How do these biases unfold over time, and what shapes their trajectory? A summary thread. (1/13)

I’m happy to be at #VSS2025 and share what our lab has been up to this year!

I’m also honored to receive this year’s young investigator award and will give a short talk at the awards ceremony Monday

Despite everything going on, I may have funds to hire a postdoc this year 😬🤞🧑‍🔬 Open to a wide variety of possible projects in social and cognitive neuroscience. Get in touch if you are interested! Reposts appreciated.

Congrats Natalia!!

Shown is an example image that participants viewed either in EEG, fMRI, and a behavioral annotation task. There is also a schematic of a regression procedure for jointly predicting fMRI responses from stimulus features and EEG activity.

I am excited to share our recent preprint and the last paper of my PhD! Here, @imelizabeth.bsky.social, @lisik.bsky.social, Mick Bonner, and I investigate the spatiotemporal hierarchy of social interactions in the lateral visual stream using EEG-fMRI.

Hippocampal encoding of memories in human infants Humans lack memories for specific events from the first few years of life. We investigated the mechanistic basis of this infantile amnesia by scanning the brains of awake infants with functional magne...

Why do we not remember being a baby? One idea is that the hippocampus, which is essential for episodic memory in adults, is too immature to form individual memories in infancy. We tested this using awake infant fMRI, new in @science.org #ScienceResearch www.science.org/doi/10.1126/...
