 De Almeida obtained his B.A. in social communication from the Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS), his M.A. in philosophy from USP, and his Ph.D. in philosophy from McMaster University (Canada). Currently a professor at PUCRS, his main area of research is epistemology. He has written on epistemic closure and skepticism—arguing inter alia that neither knowledge nor epistemic justification are closed under logical implication and that this closure-failure does not affect Cartesian skepticism (de Almeida 2007, 2012)—and on Stroud’s influential interpretation of Cartesian skepticism, which de Almeida claims is crippled by a level confusion (de Almeida 2016).
