Freire began his mathematical education at the Instituto de Matematica Pura
e Aplicada (IMPA, Rio de Janeiro, Brazil), where he worked in dynamical systems under the
direction of Ricardo Mane' (from 1978 to 1982). From 1982 to 1987 he was a graduate student
at Princeton University and the University of California, San Diego. His Ph.D. (Princeton 1988)
was awarded  for a thesis on the Martin boundary (positive harmonic functions)
of manifolds of non-positive curvature, written under the direction of Shing-Tung Yau.
From 1988 to 1991 he was Szego Assistant Professor at Stanford University. Freire joined the
UTK faculty in August of 1991, and was promoted to Associate Professor
in June of 1995. He has held visiting positions at Warwick University (Spring 1990), the
ETH Zurich (Winter/Spring 1993), the University of Bonn (Fall 1996) and the
Max Planck Institute for Gravitational Physics in Potsdam (Spring 2007). His research
was supported from 1994 to 2001 by grants from the National Science Foundation
(Geometric Analysis program). From September 2002 to August 2004, Freire served as program director in the
Division of Mathematical Sciences of the National Science Foundation (Arlington, VA.)

At UTK, Freire has served on the Faculty Senate (2015-2017) and as Mathematics Graduate Asssociate Head (2019-2022)
