Aron Simis　is Professor Emeritus:　 Universidade Federal de Pernambuco, Recife, Brazil, and a Class A research　scholarship　recipient from the Brazilian Research Council.[1]　He earned his　Ph.D.　from　Queen's University, Canada. He has previously held a full professorship at IMPA (Instituto de Matemática Pura e Applicada) in　Rio de Janeiro, Brazil. He was president of the Brazilian Mathematical Society and a member on several occasions of international commissions of the IMU (International Mathematical Union) and TWAS (Academy of Sciences for the Developing World).[2] At large he is a　John Simon Guggenheim Fellow[4]　and has been awarded other fellowships from the　Max Planck Institute, Japan Society for Promotion of Science, and the Istituto Nazionale di Alta Matematica. He is a member both of the　Brazilian Academy of Sciences　and the Academy of Sciences for the Developing World (Trieste,　Italy). His main research interests in mathematics include main structures in　commutative algebra; projective varieties in　algebraic geometry; aspects of　algebraic combinatorics; special graded algebras; foundations of Rees algebras; cremona and　birational maps; algebraic vector fields; differential methods.
