Miriam Manoel, an Associate Professor at the Instituto de Ciências Matemáticas e de Computação (ICMC) on the São Carlos campus of the University of São Paulo, is visiting the Surrey Department of Mathematics for a year supported by a Brazilian FAPESP “Bolsa Pesquisador no Exterior” (Research Fellowship Abroad) on “Symmetries of Functions on Networks and Mappings on Minkowski Spaces”.  Miriam’s host at Surrey is Mark Roberts, and they will be collaborating on the invariant and singularity theories of functions on networks. Miriam’s website at USP can be found here.
