After receiving his doctorate, he attained two post-doctoral degrees, one of which was from the Fernand Braudel Center/Maison des Sciences de l'Homme, Paris, France (1993–94).

He also argues that the effects of European colonialism did not cease with the processes of decolonization and national independence of the nineteenth and twentieth centuries, persisting in culture and ways of thinking (epistemology).

It proposes a "decolonial turn" to carry out epistemological decolonization that corrects the universalist and ahistorical deformations of Eurocentrism and modernity, which it considers in a situation of "terminal crisis".

It puts the accent on the critique of racism and the dividing line that colonial thought makes between the human and the non-human.

It defends the idea of intersectionality of categories such as class and gender, starting from the line of distinction between the human and the non-human that colonial epistemology does.
