Innovation of Spectroscopic Techniques

Research Interests

Polarized Resonance
Synchronous Spectroscopy
(PRS2)

Our group has developed multiple innovative spectroscopic techniques including PRS2 and PAOS, which can quantify 7 new optical parameters that allow us to understand new insights of advanced optical materials and molecular assembly process. This is the main research area in our lab. 

Raman Spectroscopy

Raman spectroscopy is a very powerful analytical method, but it still has some limitations. Our project will focus on making an innovative substrate to enhance performance of Drop Coating Deposition Raman (DCDR) and Surface Enhanced Raman (SERS). 

 

Interfacial 
Interactions

We are interested in the ligand adsorption and desorption and displacement, and reaction on the plasmonic gold nanoparticle and silver nanoparticles.  The model ligands include proteins, DNA, and small molecules such as electrolytes, organothiols, thioamides, and other organic species.

ABOUT US

We are analytical or physical chemists who utilize light for material characterizations. Light/matter interactions are likely the most studied topic in science and the phenomena from light/matter interactions are used extensively for a wide range of material characterizations.  Unfortunately, existing photon absorption, scattering, and fluorescence measurements often ignores the complex interplay of the photon absorption, scattering, and on-resonance emission that can concurrently occur in many realistic samples. Our group has recently invented a new spectroscopic method termed as “Polarized resonance synchronous spectroscopy (PRS2)”.  When used in combination with conventional UV-vis and fluorescence measurements, this PRS2 spectroscopic technique has enables for the first time the quantitative decoupling of the interplay of the material photon absorption, scattering, and on-resonance fluorescence emission. Current research in our group is on the PRS2 applications in material characterizations.

Join Us

Graduate Students


Graduate students interested in joining the group should have a strong passion and determination for scientific discovery and technological advance We welcome inquiries about our research by prospective graduate students.

Undergraduate Students


Undergraduate research is an outstanding learning experience and is all but essential for students interested in graduate school in the analytical sciences. Advanced coursework is not required provided you possess genuine enthusiasm and interest in chemical measurements and material characterizations.
