My research involves using nonlinear vibrational spectroscopy, specifically broadband vibrational sum-frequency generation (BBSFG), to probe surfaces and buried interfaces. I am interested in studying these surfaces at the molecular level to make connections between molecular structure and function. For example, in an adhesive interface, only the molecules at the interface are involved in forming the adhesive bond. How do changes in that molecular structure affect the strength of the adhesive? How does that structure change over time, possibly weakening the bond? We also investigate molecular interactions at surfaces, such as take place in a separations column.

Students in my research group work with a state of the art ultrafast laser system to perform experiments. Students also have hands-on experience designing experiments and preparing samples for analysis.
