I'm honored to receive the Penn AI Fellowship with support from @upenndddi.bsky.social! The fellowship supports my research on computational models of perception and cognitive bias. Specifically, we want to understand when and why both brains and AI systems are susceptible to cognitive biases.

Thousands of Minnesotans marched in downtown Minneapolis to protest ICE. The wind chill was 30 below during the march.

Hundreds of businesses closed their doors Friday in support of the protest as activists urged Minnesotans to abstain from economic activity.

The serotonin 1B receptor is required for some of the behavioral effects of psilocybin in mice - Molecular Psychiatry Molecular Psychiatry - The serotonin 1B receptor is required for some of the behavioral effects of psilocybin in mice

New paper drop! πŸ§ πŸ’Š Our new paper out in Molecular Psychiatry shows that the serotonin 1B receptor is important for the neural and antidepressant/anxiolytic behavioral responses to psilocybin in mice.

very excited to share some of the final bits of work from my PhD! πŸŽ‰ we find that phasic DA in the accumbens simultaneously tracks persistent motivation towards reward cues in addition to new learning (but maybe not RPE?!) in sign-tracking rats. check out the preprint below!

we find discrepancies between automated measures (eg lever pressing) of sign-tracking and the true underlying behavior. we don't think you should trash these types of measures altogether, but we do think it's a good idea to start doing some video analysis for the most accurate portrayal of behavior.

despite the horrors, I will continue to share and engage with science without fear!! thus, I'm very happy to share my recent article out in Learning & Memory. I'm so proud of this work. it's been my little passion project for some time now. a student of mine, Angela Shang, even made the cover art!

Step 1) find your rep

Step 2) send an email or call their office

Step 3) tell them that federal spending on scientific advancement is the best hope we have to β€œwin against china” or whatever these guys are obsessed with these days
