Enrique Ramiro Pujals is an Argentine-born Brazilian mathematician known for his contributions to the understanding of dynamical systems. He currently works as full researcher at IMPA.
After earning an undergraduate degree in mathematics at the University of Buenos Aires in 1992, he became a Ph.D. student at the Instituto Nacional de Matemática Pura e Aplicada, where he was a student of Jacob Palis, Jr., completing his Ph.D. in 1996. He was a Guggenheim Fellow in 2000.
He was an invited speaker at the International Congress of Mathematicians in Beijing 2002. Won the ICTP Ramanujan Prize (2008), UMALCA Prize in Mathematics (2004), TWAS Prize in Mathematics (2009) and is a member of the Brazilian Academy of Sciences.
