Dr. Yokaichiya is a researcher and an instrument scientist for the 2-axis diffractometer (E4) and for flat cone diffractometer (E2) at Helmholtz-Zentrum Berlin für Materialen und Energie (HZB), Germany. He graduated as an electronic engineer at Federal University of Parana (UFPR- Brazil) in 1995, and received his PhD degree in Physics at the University of Campinas (UNICAMP- Brazil) in 2003. With his PhD research, he studied strong correlated systems using synchrotron radiation facilities. From 2005 to 2010 he has worked as a post-doctorate in several laboratories like Laboratoire Louis Néel in Grenoble (France, 2005), Brookhaven National Laboratoy (USA, 2006) and Helmholtz-Zentrum Berlin (Germany, 2007-2010). From 2010 to 2013, Dr. Yokaichiya has worked at LNLS as a beamline scientist responsible for the X-ray powder diffraction beamline (XPD). His main projects are concerned to magnetic materials, drug delivery systems and cement/concrete systems.
