Neuroscientist | BRAIN K99 Fellow at Princeton 🔜 Assistant Professor at Utah
Joined September 2020
I’m very excited to share that I will join the University of Utah Department of Neurobiology as an Assistant Professor in Jan 2026!! 🎉🏔️🏜️. My lab will focus on body–brain interactions in learning & memory — how do signals from our internal organs remodel the brain & behavior?

I’m especially grateful to my wonderful mentors — Ilana Witten @PrincetonNeuro and @zaknight @UCSFPhysiology — for all of their support and guidance over the past twelve (!) years. And looking forward, I’m thrilled to be joining the incredible neuroscience community at Utah! 😃.

Research in our lab will bring together tools and perspectives — from systems and computational neuroscience, physiology, genomics, and biochemistry — to study how animals learn from feedback from the gut (and other organ systems). I will be recruiting lab members at all levels!.

I'm happy to share the final version of our paper in @Nature this week, with a lot of new data!. 📄: This would have been impossible without support from the NIH (especially BRAIN Initiative), as well as @HHMINEWS, @SimonsFdn, @PrincetonNeuro, HHWF, BRF.

Nature - Illness signals from the gut reactivate and strengthen flavour representations in the amygdala to support learning from delayed postingestive feedback.
How do we associate the flavors we experience during a meal 🍽️😋 with postingestive effects, like food poisoning 🤢🤮, that arise minutes or hours later? My new preprint with @IlanaWitten digs into how the brain solves this credit assignment problem. 1/4

Our results show that interoceptive reactivation of amygdalar flavor representations provides a neural mechanism to resolve the credit assignment problem in postingestive learning. Find all of the details including new brainwide imaging and Neuropixels tech @biorxiv_neursci! 3/4.
