The brain is a network of billions of neurons that are interconnected by synapses. Each synapse is made up of more than a thousand different proteins, that exist at a wide range of copy numbers from just a few to thousands, and ordered in a volume of micrometer in length scale. The focus of our lab is to acquire a quantitative mechanistic characterization of synaptic players at different length scales, from a single protein to the synapse level, to describe this complexity and towards understanding of the molecular nature of information processing in the brain. We do so by developing quantitative biophysical and cell biology analyses using cutting edge single molecule and high throughput approaches that draw from cell biology, chemistry, physics and engineering.
