Enrique Ramiro Pujals is an Argentine-born Brazilian mathematician known for his contributions to the understanding of dynamical systems.〔http://www.biotech.ncku.edu.tw/files/news/22_bddac7ed.pdf〕〔http://www.ams.org/notices/200902/rtx090200268p.pdf〕 He currently works as full researcher at IMPA.〔http://www.impa.br/opencms/en/pesquisa/pesquisa_pesquisadores/pesquisadores_enrique_ramiro_pujals/pesquisadores_enrique_ramiro_pujals.html〕 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. He was a Guggenheim Fellow in 2000.〔http://www.gf.org/fellows/all-fellows/enrique-ramiro-pujals/〕 He was an invited speaker at the International Congress of Mathematicians in Beijing 2002.〔http://www.mathunion.org/db/ICM/Speakers/SortedByLastname.php〕〔http://www.umalca.org/web/?page_id=605〕 Won the ICTP Ramanujan Prize (2008), UMALCA Prize in Mathematics〔http://www.matmor.unam.mx/eventos/latino/〕 (2004), TWAS Prize in Mathematics〔http://twas.org/article/twas-announces-2009-prize-winners〕 (2009) and is a member of the Brazilian Academy of Sciences.〔http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4767395E9〕 ==Selected publications== *Pujals, E.
