H. Tolentino

Hélio Tolentino took Physics at the Paraná Federal University (1981-85), where he initiated his expertise in X-ray optics in Prof. Cesar Cusatis' group. Then, he moved to the University of São Paulo (USP) – campus São Carlos to work on X-ray instrumentation in the Optics Group (1985). He got a Master's degree in Physics in 1986, under Prof. Ricardo Rodrigues. After that, Hélio moved to France to develop research using X-ray absorption spectroscopy to understand high Tc superconductors' atomic and electronic structure. In 1990, he got a doctorate (Ph.D.) in Solid State Physics from the Université Paris-Sud, campus Orsay, under Dr. Alain Fontaine. Just after his thesis, in 1991, HT joined the LNLS team to build the first synchrotron light facility in Brazil. In 2005, Hélio left LNLS and moved back to France. He worked until 2014 at the Institut Néel – CNRS & UJF, emphasizing surface X-ray diffraction and magnetic thin films, and at the European Synchrotron Radiation Facility – ESRF, Grenoble. Since 2014, Hélio is a Senior Researcher at the Brazilian Synchrotron Light Laboratory (LNLS), which is part of the Brazilian Center for Research in Energy and Materials (CNPEM) in Campinas SP, Brazil. He serves as Head of the Heterogeneous and Hierarchical Matter division of LNLS. He is also a researcher (on leave for an extended period) of the CNRS, France. Hélio has experience in condensed matter physics, scientific instrumentation, and synchrotron light science. His research interest includes materials for energy and photonics, nanomaterials, coherent X-ray properties, and instrumentation for synchrotron light.
