Our research focuses on determining the structures and interactions of macromolecules by ion mobility / mass spectrometry. We are interested in macromolecular systems of both industrial and biological importance. The two main areas of research are chemokine-mediated chemotaxis of immune cells and the structural determinants of non-conventional oils. The work is a blend of experiment and theory that brings a structural perspective to two of the Grand Challenges of the 21st century, health and energy
