Research Overview

Brain cell regeneration, automated microscopy and laser surgery, user-friendly and low-cost fluorescence microscopy

NeuroLab

The NeuroLab focuses on the fascinating field within neuroscience. We study a remarkable effect called lesion conditioning, which promotes regeneration in the mammalian central nervous system. We uniquely model lesion conditioning in the roundworm C. elegans, allowing us to examine genetic mechanisms of regeneration at a single-cell resolution.

Our laboratory uses advanced microscopy techniques that enable us to visualize and analyze the complex cellular structures of C. elegans. We utilize a femtosecond laser to sever single neuron fibers and study their regenerative capacity under different pathways.

We aim to automate these techniques to streamline immobilization, imaging, laser surgery, and reimaging of animals.

Our interdisciplinary approach produces important insights into the mechanisms of neuroregeneration, toward the long-term goal of developing therapies for neurological injuries and diseases.
