Dylan received an MSci in Physics in 2004, an MRes in Protein and Membrane Chemical Biology in 2005 and a PhD in biophysics and biomedical optics in 2008 all from Imperial College London. His PhD was jointly supervised by Prof. Paul French and Prof. Tony Magee in the Department of Physics and the National Heart and Lung Institute respectively where he developed new fluorescence microscopy methods to study cell membranes. In 2008 he moved to the Centre for Vascular Research at the University of New South Wales, Sydney, Australia to work in the group of Prof. Katharina Gaus. He applied super-resolution fluorescence microscopy methods to study immune cell interactions. He moved to King’s College London in January 2013 as part of a joint appointment between the Department of Physics and the Randall Division of Cell and Molecular Biophysics.
Dylan’s research interests are in the development and application of cutting-edge fluorescence microscopy techniques and their applications to cell biology, in particular the study of cell membranes and T cells. The microscope techniques particularly include super-resolution fluorescence imaging based on single-molecule detection, structured illumination as well as associated data analysis. He also works with environmentally-sensitive fluorescent probes with spectrally-resolved detection as well as fluorescence lifetime imaging. These are applied to cell biology applications. He is particularly interested in the structure and function of the cell membrane and how this regulates cellular signalling events. An especially important application of this is the study of the T cell immunological synapse between the immune cell and its target cell during an immune response.
