We focuses on the utilization and development of Raman spectroscopy to expand our understanding of the physical and chemical processes on surfaces and interfaces concluding inside biological systems. In particular, we are interested in using plasmon-based methods to obtain the molecular signatures of above systems with improved sensitivity, spatial resolution and time resolution, including surface-enhanced Raman spectroscopy (SERS), and dark field methods.

Currently, at the fundamental level, we are interested in using low-dimensional materials, and metallic alloy nanoparticles for SERS. In these materials systems, we aim to establish synthesis-structure-property relationships, and to understand and control their surfaces and interfaces.  These insights are helping to guide our interest in impacting areas such as environment, health, sustainability and energy.

We are a truly interdisciplinary group, ranging from chemistry, physics, biology, material sciences and instrumentation. We are also an open group welcoming scientific collaboration, particularly with those groups with biology, physics and material science background.
