Prof. Ren's group focuses on the utilization and development of Raman spectroscopy and electrochemical methods to study the physical and chemical processes on surfaces and interfaces and in biological systems. In partlcular, 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), tip-enhanced Raman spectroscopy (TERS), dark field methods, and their combination with nanoelectrochemistry. 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. We have always open positions for talent and self-motivated students and postdoctors.
