#introduction I'm currently a staff scientist at Washington U in St Louis (USA), but (late 2026, early 2027) looking for a new position. I'm a big fan of task #fMRI, #BIDS, #baseR #Rstats (incl. graphics) and #knitr, #QC, and papers with very extensive #supplementary materials, but not AI.

🚨 New paper in @nature.com We asked why two hippocampal areas with very different anatomy, CA3 and CA1, often seem to code space so similarly? By recording bats flying up to 200m, we found that the difference was hidden by scale! www.nature.com/articles/s41... 🧵 1/11

When you're stressed, what happens to the mental links that let you connect related experiences and draw new conclusions? In our new @science.org #ScienceAdvances paper, we show that stress disrupts that linking process in the hippocampus🧵

Super excited to (finally!) show our work on identifying cell types! Now in press www.nature.com/articles/s41.... We show how to identify cell types from ephys recordings *without* optotagging. This opens the study of not just individual cell types, but the interacting neural circuit during behavior

Maps are everywhere in the brain...and finally we've discovered one in the nose! Led by @davidhbrann.bsky.social, we uncovered the logic that specifies the positions of each of the 1,000 sensory neuron subtypes in the nose and aligns their projections to the brain.👇👃see more details below👃👇

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/...

Excited to share our latest story! We found disentangled memory representations in the hippocampus that generalized across time and environments, despite the seemingly random drift and remapping of single cells. This code enabled the transfer of prior knowledge to solve new tasks

Basis functions for complex social decisions in dorsomedial frontal cortex - Nature
A study combining group decision-making tasks with fMRI shows that the brain’s dorsomedial prefrontal cortex uses basis functions, similar to those in the visual, motor and spatial domains, to represent patterns of social interaction.
