Dr. David Aragão studied organic chemistry at the Universidade Nova de Lisboa (FCT-UNL, Portugal). From early undergraduate days he got interested in structural biology having spend time in international laboratories like the EMBL, Grenoble, France and University of Georgia, Athens, USA. After graduating in chemistry David worked for a 2-year period as a research assistant in Protein Crystallography with particular emphasis on metalloproteins (2000-2001). From here he then followed to a joined Ph.D between the European Synchrotron Radiation Facility (ESRF, France) and the Instituto de Tecnologia Química e Biológica (ITQB-UNL, Portugal) where the metalloproteins research path was expanded to enzymes involved in bacterial biofilm formation. In 2008 he moved to Ireland, under Prof. Martin Caffrey's supervision, as a NHI funded Postdoctoral Research Fellow (University of Limerick) and later successfully obtaining a prestigious IEF Marie Curie Fellowship to work at Trinity College Dublin. During this period he specialized in the membrane protein field working in diverse important targets from GPCRs, membrane metalloproteins and several P. aeruginosa membrane proteins involved in biofilm, membrane kinetics, ABC-transporters and others. In 2011 he joined the Australian Synchrotron for a two year period as a beamline postdoc and after a brief stunt jointly appointed by the Australian Synchrotron and Victor Chang Cardiac Research Institute he became a Beamline Scientist the Australian Synchrotron. His current research interests lie in field of membrane structural biology namely membrane metalloproteins, ABC- transporters, ATP synthases but also crystallography and beamline method developments related to micron-beams, lipid cubic phase, multi-crystal data merging just to name a few.
