Marcelo Miranda Viana da Silva (born 4 March 1962) is a Brazilian mathematician working in dynamical systems theory.
He was a Guggenheim Fellow in 1993.
Viana was vice-president of the International Mathematical Union in 2011–2014, and president of the Brazilian Mathematical Society (2013–2015).[ Diretoria - SBM - Sociedade Brasileira de Matemática]
In 1998, he was a plenary speaker at the International Congress of Mathematicians, in Berlin.
Viana is director elected of the IMPA (for the period 2016–2019).
Viana is a columnist for Folha de S.Paulo.
He was the chair of the executive committee for the 2018 International Congress of Mathematicians, Rio de Janeiro.
Biography
Viana was born in Rio de Janeiro, Brazil, his parents being Portuguese. He grew up in Portugal, and his undergraduate studies were at the University of Porto. He received his Ph.D. degree from the IMPA in Rio de Janeiro, with
Jacob Palis as advisor. He is now director at IMPA.
Work
Viana's work concerns chaotic dynamical systems and strange attractors.
