X-ray ptychographic tomography – a look inside materials with high spatial resolution



Ana Diaz has dedicated her entire career to develop X-ray characterization methods using synchrotron radiation. She did her PhD at the Paul Scherrer Institute in Switzerland on the characterization of colloidal suspensions confined in unidimensional gratings and then moved to the European Synchrotron Radiation Facility in France to work as a postdoc, where she used Bragg coherent diffraction imaging to characterize epitaxial SiGe nanocrystalline structures. She is now back at the Paul Scherrer Institute where she works as a beamline scientist at the Swiss Light Source since 2009. Ana has contributed significantly to the implementation of hard X-ray ptychography at the cSAXS beamline, in particular for ptychographic tomography, for which she has received the Helmoltz Zentrum Berlin Innovation Award on Synchrotron Radiation in 2014 for high-resolution 3D hard X-ray microscopy. Her main research interests deal with the application of X-ray ptychography to systems that cannot be easily characterized with other techniques, for example cryo-imaging of soft biological tissue or imaging atomic displacement fields in crystals. She has authored 110 publications with more than 3000 citations, according to Web of Knowledge.
