Research
Our laboratory specializes in surface and interface spectroscopy, innovating non-linear optical techniques to explore complex interfacial phenomena. By probing molecular orientation and electronic dynamics at semiconductor, electrode, and polymer boundaries, we aim to advance the frontiers of analytical chemistry and develop foundational measurement protocols for material science.
Primary Research Areas
Semiconductor Interfaces
We develop spectroscopic methods to probe buried interfaces, including semiconductor/aqueous solution interfaces. By investigating interfacial molecular structures and electronic states, we aim to understand phenomena at semiconductor interfaces.
Electrode Interfaces
We investigate the orientation and hydrogen-bond structure of water molecules, as well as electric fields, at electrode/aqueous solution interfaces. By measuring their dependence on electrode potential and solution conditions, we aim to understand the electric double layer at the molecular level.
Polymer Interfaces
We investigate molecular structures and hydration at polymer/water interfaces and hydrogel surfaces. We examine how interfacial molecular structures relate to material properties such as adhesion.
Advanced Spectroscopic Instrumentation
We develop phase-sensitive nonlinear spectroscopic instruments to measure molecular structures and dynamics at interfaces. Our work aims to enable measurements of interfaces buried beneath water and extend these methods to time-resolved studies.
