How does the brain process information across contexts?

We constantly navigate a flood of information, figuring out what matters in each moment and adapting our behavior accordingly. This ability to flexibly adapt across contexts is central to intelligent behavior. My research investigates how the brain encodes context and uses it to process information adaptively as animals switch between multiple tasks. To acheive this, I use electrophysiological recordings and computational approaches.

I am a PhD candidate in Neuroscience at Washington University in St. Louis, working with Lawrence Snyder. I received ME in Biomedical Engineering at Sungkyunkwan University in Korea, advised by Joonyeol Lee.

Is spatial memory coding consistent across tasks?

Prefrontal cortex represents spatial memory with a shared structure across tasks, while task context shifts the memory manifolds.

How does expectation modulate visual perception?

Prior expectations sharpen neural population tuning for motion direction, through different modulation of individual neurons based on their preferred direction.

Do different spatial scales of the brain support different cognitive functions?

Although scales are biologically dependent and embedded to one another, each scale may serve a causal role in different cognitive processes, which enables diverse neural computations to occur simultaneously in the brain.

Can Bayesian inference model predict eye movements?

Changes in bias and variability in smooth pursuit eye movements induced by prior knowledge were quantitatively explained by a Bayesian observer model.
