starting fall 2026 i'll be an assistant professor at @upenn.edu 🥳

my lab will develop scalable models/theories of human behavior, focused on memory and perception

currently recruiting PhD students in psychology, neuroscience, & computer science!

reach out if you're interested 😊

So, if an institute or center decided not to fund any grant from University X or on Topic Y, then there would be no documentation in the official grant files about these applications.

“Our findings challenge the conventional focus on low-dimensional coding subspaces as a sufficient framework for understanding neural computations, demonstrating that dimensions previously considered task-irrelevant and accounting for little variance can have a critical role in driving behavior.”
Neural dynamics outside task-coding dimensions drive decision trajectories through transient amplification
Most behaviors involve neural dynamics in high-dimensional activity spaces. A common approach is to extract dimensions that capture task-related variability, such as those separating stimuli or choice...

I really hate it when scientists keep saying that “we need to rebuild trust in science,” because it implies that scientists are to blame for the mistrust rather than the millions of dollars of dark money that have funded political attacks on science in order to advance a far right agenda.

Heard an established successful neuroscientist dismissing junior scientists as "people at the bottom" 🤦‍♀️

You folks with lots of research funds & power: young scientists more than ever need our respect and support even if you don't agree with their ideas and approaches
