Enrique Pujals

Enrique Ramiro Pujals is an Argentine-born Brazilian mathematician known for his contributions to the understanding of dynamical systems.^[1][2] He currently works as full researcher at IMPA.^[3]

After earning the licenciatura 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.^[4] He was a Guggenheim Fellow in 2000.^[5]

He was an invited speaker at the International Congress of Mathematicians in Beijing 2002.^[6][7] Won the ICTP Ramanujan Prize (2008), UMALCA Prize in Mathematics^[8] (2004), TWAS Prize in Mathematics^[9] (2009) and is a member of the Brazilian Academy of Sciences.^[10]
