Dr. Callum Gassner recently earned his PhD in analytical chemistry at Monash University. His research was primarily focused on the application of vibrational spectroscopic imaging techniques on biological tissues. During his doctoral studies, Callum investigated and optimized a method – polarised Fourier transform infrared microspectroscopy – to image the orientation of molecules on the microscopic scale within complex mixed samples, i.e. biological tissues. He is currently a research associate employing vibrational spectroscopic imaging techniques to a wide range of fields.
