[Research Focus]

My first encounter with neuroscience was as an applied math graduate student. I was amazed by the rich behavioral repertoire of the roundworm C. elegans, which has a small nervous system of only 302 neurons. Just a few dozen motor neurons are sufficient to coordinate the worm to move elegantly, while a few sensory and interneurons guide the animal to track chemical gradients. The mammalian brain, with millions to billions of neurons, is far more complicated and capable than a small nematode. High-level cognitive functions such as working memory, decision-making and consciousness are the biggest mysteries in the complicated nervous system. The long-term goal of our research is to understand how neural circuits in the mammalian brain implement these cognitive functions. To do so, we integrate optogenetics, multi-electrode recordings, two-photon optical imaging, and behavioral measurements to probe the neural dynamics underlying perceptual decision-making behaviors.
