New preprint led by awesome undergrad Abby Bonno! By probing temporal memory for individual items in a sequence, we uncover a 'representational space' of memories that reflects the structure of encoded experiences and provides insight into how different kinds of structure shape memory. osf.io/t5kyx
🎯New preprint!
The resource-rational dynamics of evidence accumulation
www.biorxiv.org/content/10.6...
Evidence accumulation isn’t stationary.
It is dynamically controlled to trade off information gain against cognitive effort.

Many claim memory biases toward percepts reflect corruption in sensory signals. We challenge this view by showing that ppl adapt their integration rationally w/ experience. w/ @timbrady.bsky.social
Humans adaptively integrate memory and perception based on stimulus history | osf.io/preprints/ps...
Thrilled to finally share this work! 🧠🔊
Using a new reinforcement-free task we show mice (like humans) extract abstract structure from sound (unsupervised) & dCA1 is causally required by building factorised, orthogonal subspaces of abstract rules.

Our experiences have countless details, and it can be hard to know which matter.
How can we behave effectively in the future when, right now, we don't know what we'll need?
Out today in @nathumbehav.nature.com , @marcelomattar.bsky.social and I find that people solve this by using episodic memory.
In a new paper, I delve into these two findings and muse on when prediction might help vs. hurt memory (and discuss why this matters for models of memory and the hippocampus). This is my first solo-author paper, and I had a lot of fun putting these ideas on paper! direct.mit.edu/opmi/article...
Really thrilled that this paper led by @neurozz.bsky.social is now published in its final version in @elife.bsky.social!!
This is a memory-focused (as opposed to RL-focused) account of the detailed characteristics of forward and backward awake and sleep replay!

When does new learning interfere with existing knowledge in people and ANNs? Great to have this out today in @nathumbehav.nature.com

⭐ My lab is recruiting a grad student for fall 2026! ⭐
🧠 If you are interested in semantic learning & memory, and want to use fMRI + computational models to ask these questions, I'll be excited to hear from you. Come join us in Bing!

The first chapter of my dissertation is officially published! 🎆🌺💤 We found that folks with depression show similar impairments in cognitive functioning after total sleep deprivation as non-depressed folks (and bounce back similarly after recovery sleep):

Last month, I launched my lab at Ohio State. Our lab website is now live, and we're recruiting graduate students this cycle! If you're interested in the cognitive (neuro)science of learning & memory, please reach out!

If you’re heading to SF for #CogSci2025 this week and are interested in mobile EEG or spatial memory, come check out my talk on Thursday! (Talks 11: EEG, 2:15pm, Salon 5).
Excited to share a new preprint w/ @annaschapiro.bsky.social! Why are there gradients of plasticity and sparsity along the neocortex–hippocampus hierarchy? We show that brain-like organization of these properties emerges in ANNs that meta-learn layer-wise plasticity and sparsity. bit.ly/4kB1yg5
Incredibly excited and grateful to share that I’ll be starting a lab at The Ohio State University this(!) fall! My lab will study human learning and memory, with related interests in sleep, stress, and time perception. More info soon, but do get in touch if you’re interested in joining!
preprint alert 🚨
1/ Can we accurately detect sequential replay in humans using Temporally Delayed Linear Modelling (#TDLM)? In our recent study, we could not find any replay and decided to dig deeper by running a hybrid simulation with surprising results. Link to preprint & details below 👇
New MEG paper by @jhaarsma.bsky.social and @dotproduct.bsky.social! Same design and behavioural results as our 7T layer fMRI study (www.jneurosci.org/content/43/4...), but now shedding light on the temporal dynamics of the sensory signals underlying false percepts. #neuroskyence
New preprint! How do we integrate new information into prior knowledge? We find that existing knowledge enables rapid new learning but that interleaved replay during sleep promotes integration of new and old information. Modeling suggests a sleep context suppression mechanism.

I’m thrilled to announce that I will start as a presidential assistant professor in Neuroscience at the City U of Hong Kong in Jan 2026!
I have RA, PhD, and postdoc positions available! Come work with me on neural network models + experiments on human memory!
RT appreciated!

New preprint! Statistical structure skews object memory toward predictable successors. Model simulations show how this bias can arise from the backward expansion of hippocampal representations.
