Dr. Martin Walsh, is deputy to the director of life sciences at Diamond Light Source (DLS) where he coordinates life science research. He obtained his first degree in Chemistry from University College Galway in 1989 and continued his career there through research work for his PhD which contributed to the establishment of a protein crystallography group in Ireland. and the determination of the first macromolecular structures from an Irish based research group. In 1994 he moved to York with Guy Dodson and from here took the opportunity to accept a short term visiting fellowship to the EMBL outstation at Hamburg to exploit synchrotron radiation for collection of atomic resolution data from proteins under the guidance of Keith Wilson. He has extensive synchrotron MX experience having worked at DESY Hamburg, APS Chicago, ESRF Grenoble and DLS, Oxford. He has accumulated 28 year’s experience in macromolecular X-ray crystallography (MX) and has deposited >100 structures with the Protein Data Bank. He has extensive experience in the determination of macromolecular structures and has been at the forefront of high throughput developments in crystallography which have facilitated the collection of the best data from the most challenging of samples. His research interests are focused on respiratory pathogens and mechanisms used by bacteria to colonize and persist in the human host.
