WelWelcome to the Wei Research Group! 

We are a team of passionate researchers with interdisciplinary backgrounds of optical microscopy, physical chemistry and chemical biology! We develop next-generation optical imaging techniques based on nonlinear vibrational spectroscopy to visualize dynamical biological processes with better spatial, temporal and molecular precision.
