Dr Damien Callahan is currently a Chemistry lecturer in the School of Life and Environmental Sciences at Deakin University (Melbourne, Australia) and also holds and honorary position in the School of Botany at The University of Melbourne. His primary areas of research are in LC-MS method development in Metabolomics, applied research on metal hyperaccumulating plants and microalgal lipid biochemistry in the Centre for chemistry and Biotechnology at Deakin University. He has more than 15 years of experience in analytical chemistry in both industry and academic environments. His research has advanced the methodology used for small molecule and lipid analysis in the rapidly progressing field of metabolomics. The development of new analytical techniques for small molecule and lipid analysis was the major focus his recent postdoctoral research career where he made significant contributions to the development of the world leading Metabolomics research facilities of Metabolomics Australia. The methodology he developed while working in metabolite profiling has been applied to large number of fields, in particular metal hyperaccumulating plants, as well as diabetes research, algae biofuels, fungal secondary metabolites, plant taxonomy and plant and fungal mineral nutrition.
