Enrique Ramiro Pujals is a Brazilian mathematician known for his contributions to the understanding of

dynamical systems In mathematics, a dynamical system is a system in which a function describes the time dependence of a point in an ambient space. Examples include the mathematical models that describe the swinging of a clock pendulum, the flow of water in a p ...

Education

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, completing his Ph.D. in 1996. He was a Guggenheim Fellow in 2000. Before moving to CUNY in 2018, he was a faculty member at IMPA since 2003.
