Henrique

Henrique Cota de Freitas received his BS in Computer Science (2000) and M.Sc. in Electrical Engineering (2003) from the Pontifícia Universidade Católica de Minas Gerais (PUC Minas), Belo Horizonte, Brazil, and Ph.D. in Computer Science  (2009) from the Universidade Federal do Rio Grande do Sul (UFRGS), Porto Alegre, Brazil. From 2011 to 2013, he was the Head of the Graduate Program in Informatics at PUC Minas. In 2015-2016, he was a visiting researcher at INRIA and Université Grenoble Alpes (GIANT campus), Grenoble, France, funded by the Brazilian Research Council (CNPq). He is a member of IEEE and SBC (Brazilian Computer Society), and since 2004, he is a professor at PUC Minas.
