The first manuscript based on my lab's data! We show that dopamine activity in the ventral striatum encodes moment-by-moment temporal-difference error during aversive situations, suggesting that dopamine can be a unified teaching signal across valences. doi.org/10.1101/2025...

A unified derivative-like dopaminergic computation across valences
Dopamine activity in the brain affects decision-making and adaptive behaviors. A wealth of studies indicate that dopamine activity encodes discrepancy between actual and predicted reward, leading to t...

Our work with Pablo Tano, @hyunggoo-kim.bsky.social Athar Malik, Alexandre Pouget and @naoshigeuchida.bsky.social exploring how dopamine neurons could enable multi-timescale reinforcement learning in the brain is out in @nature.com www.nature.com/articles/s41...

Excited to share my first post here! Our new paper reveals a top-down breathing circuit that slows breathing to ease anxiety & fear. A step forward in understanding how brain-breathing interactions shape emotion. Published in Nature Neuroscience—grateful to my team! www.nature.com/articles/s41...

I am recruiting graduate students for my lab @mcgillu.bsky.social for admission in Fall 2025! Get in touch if you're interested in how brain circuits implement distributed computation, including dopamine-based distributed RL and probabilistic representations.
