"Progress in science depends on new techniques, new discoveries, and new ideas, probably in that order" - Sydney Brenner

In the lab, we develop new methods and platforms for enabling large-scale recording and manipulation of neurons in the living brain. We believe that this approach is essential for a  better understanding of how the spatially-distributed and highly-interconnected circuits in the mammalian brain integrate sensory input and transform it into motor action, especially in the context of neurodegeneration or various neurologic conditions. This type of computation is also involved in almost any behavior or decision-making process we do in our everyday life; therefore, we want to gain a deeper understanding of its nature. We work with state-of-the-art optical tools, such as ultrafast lasers, nonlinear microscopy and high-harmonic generation, as well as with novel protein sensors and actuators for detecting and manipulating the brain activity.

The research in the lab is interdisciplinary and collaborative in its nature, and combines approaches from different fields, like engineering, physics, structural biology, and systems neuroscience. Our current projects focus on changes to the brain activity following an injury, and use rodent models of myelin injury, traumatic brain injury, and stroke injury. Another project develop the method and application for recording detailed brain activity from freely-moving rodents.
