I'm recruiting PhD students to join my new lab in Fall 2026! The Shared Minds Lab at
@usc.edu
will combine deep learning and ecological human neuroscience to better understand how we communicate our thoughts from one brain to another.

Years ago my lab tried to brainstorm ways to separately manipulate low-level (texture/pattern) and high-level (scene/object) image properties, for studying visual representations in the brain. Thanks to imaginative work by PhD student Zall Hirschstein, we now have a stimulus set that does just that!

Does watching a movie over and over make events slower or faster in the brain? With Narjes Al-Zahli and

we find that different regions actually change in different directions, e.g. visual regions show finer-scale event structure and STS shows coarser-scale structure!

What drives human curiosity? Is it a need to balance stimulation โ or something we learn over time? In our ๐จ new preprint, we show that learning reinforces curiosity, especially for related content.

New paper story time (now out in PNAS)! We developed a method that caused people to learn new categories of visual objects, not by teaching them what the categories were, but by changing how their brains worked when they looked at individual objects in those categories.
