The Foster group does surface chemistry and experimental physical chemistry. We use optical spectroscopies, such as diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), and scanning probe microscopies, such as atomic force microscopy (AFM), and combination techniques, such as a Raman microscope, to study chemical reactions and proecesses happening at complex interfaces.
