To perform complex behaviors in the real world, our brain must combine information from multiple senses at once. Yet each sense captures the world in a completely different format: light for vision, sound waves for hearing, pressure for touch. My research asks how the brain seamlessly combines these different sensory streams into a single, coherent picture of the world, and how this shapes what we perceive and how we act.

Our eyes are rarely still. We shift our gaze several times per second to explore our surroundings. Each time we do, the image on our retina jumps abruptly. Yet we never notice this disruption; the world appears stable and continuous. My research investigates how the brain accomplishes this, tracing the underlying mechanisms from early neural signals to higher-level cognitive processes that together create a seamless visual world.

At any moment, our eyes are flooded with more visual information than the brain can process in detail. Rather than analyzing every item, the brain often extracts a quick summary, or "gist," of the group as a whole (e.g., such as average size or expression). My research explores how the brain forms these ensemble representations, especially in the dynamic visual scenes we encounter in everyday life.
