My personal research interests are concentrated in many different aspects of Nuclear Physics Sciences. My main activity is to study relativistic heavy-ion reactions focusing the different aspects of heavy-flavor production and their interaction with the matter created in such collisions. In order to carry these activities I am member of the STAR collaboration at the Relativistic Heavy-Ion Collider (RHIC) in the Brookhaven National Laboratory , USA. Our research group is also member of the Alice experiment at the Large Hadron Collider (LHC), located at Cern . Other basic research activities include the study of nuclear reaction dynamics at low energy collisions and nuclear astrophysics. These activities are carried mainly in the Pelletron Laboratory at the University of São Paulo, Brazil. I also give particular attention to nuclear instrumentation research, focusing mainly in the development of data acquisition systems for low-energy nuclear accelerators.
