====== Alfredo Miguel Ozorio de Almeida ======


===== Biography =====
Holds degrees in Mathematics and Physics - University of Bristol (1970) and PhD in Physics - University of Bristol (1973). He is currently a senior researcher at the Brazilian Center for Research in Physics. Has experience in Physics, with emphasis in General Physics, acting on the following subjects: chaos, the Wigner function, periodic orbits and space phase. Since 2002, has been incorporating the semiclassical study of open quantum systems methods.
