I finished my undergraduate studies in Physics at the Federal University of Minas Gerais in Belo Horizonte, Brazil in 1985 and obtained my Master´s degree in Physics at the Campinas State University (UNICAMP), also in Brazil in 1988, presenting results of theoretical work on the scattering of low energy electrons by small molecules. In 1987, I joined the LNLS (Laboratório Nacional de Luz Síncrotron) team to participate in the early stages of the design and construction of an electron linear accelerator (LINAC) which would later become the injector of the first synchrotron radiation source in the Southern Hemisphere. From 1988 to 1991, I was involved in several aspects of the design and commissioning of various accelerator subsystems and worked on beam dynamics simulations in the low-energy LINAC pre-injector as well as with longitudinal beam dynamics in the 120 MeV RF linear accelerator and the study of collective beam instabilities in the 1.37 GeV electron storage ring. I was particularly involved in estimating the effects of ions trapped in the stored electron beam and presented my PhD thesis on this subject in 1994, at the University of Campinas. This experimental work involved the development of a gamma ray Cerenkov detector to observe bremsstrahlung produced by the electron beam as it collides with trapped ions, allowing the localized observation of ion effects in storage rings and was performed at the Electron Positron Accumulator (EPA), which was then a part of the LEP (Large Electron Positron Collider) injector chain at CERN in Geneva, Switzerland, where I worked as an associate researcher from October 1991 to June 1993. After returning to Brazil and becoming the leader of the LNLS Accelerator Physics Group, I was involved with electrical and optical diagnostics for the electron beam, having coordinated a research project (young researcher grant) which funded the hardware for the diagnostics synchrotron beam lines at the LNLS storage ring and participated in the design of beam position monitors and tune measurement systems. At that time, I was also the coordinator of development activities related to the conceptual design and implementation of the high level layer of the control system for the LNLS accelerators. Finally, I was deeply involved in the commissioning of the LNLS injector LINAC and storage ring, which became operational with full user access in July 1997 In June 1998, I became head of the Accelerator and Scientific Instrumentation Division at LNLS, having responsibility to coordinate the work of over 70 people in more than 10 different Physics and Engineering development groups, including Accelerator Physics, RF, Vacuum, Mechanical Technologies, Diagnostics and Controls. As Division Head, I was involved in all upgrade and improvement programs for the LNLS light source as well as with beam dynamics studies. In particular, I was the Project Leader for the design and construction of a 500 MeV booster synchrotron, built with the purpose of optimizing the injection process into the storage ring. The booster synchrotron, a three-year US$2 M project, was completed in July 2001 and allowed the current in the LNLS storage ring to be raised far above the original specifications. In August 2002, I became Associate Director of ABTLuS, the organization which runs LNLS under a contract with the Brazilian Ministry of Science and Technology. Over the past years, I have continued to work on accelerator developments and beam dynamics. In particular, I coordinated the teams involved in a variety of upgrades and improvements to the LNLS light source, such as the design, construction and commissioning of the first two insertion devices to be installed in the LNLS storage ring in 2005 (a 2.0 T hybrid wiggler) and 2007(and elliptically polarizing undulator), as well as the specification of the first superconducting wiggler to be installed in the Brazilian ring. I also helped to implement methods to fight the effect of coher (Source: Lattes Curriculum)
