Curriculum Vitae

Research Area

My research program focuses on using synthetic methods to prepare organic molecules functionalized as analytical approaches to quantitatively measure small molecules with extremely low concentration in the nature on the basis of spectroscopic information. My research interest includes: 1) design novel sensing switches with high affinity and sensitivity to target molecules based on molecular recognition; 2) develop novel fluorescent molecules and understand their fluorescence features; 3) use designed sensing approaches to investigate the roles of important molecules in the biological systems; 4) use nanoparticles to improve the stability and permeability of fluorescence sensors for their biological applications.
