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...

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...

Multi-timescale reinforcement learning in the brain - Nature Individual dopaminergic neurons encode future rewards over distinct temporal horizons.

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

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!

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.
