He is expanding his interests in language policy and planning into the area of Southern Epistemologies and Ontologies. He has recently co-authored a book on Southern Epistemologies with Alastair Pennycook, titled Innovations and Challenges in Applied Linguistics from the Global South (Routledge), which is a development of their previous work on the “Disinvention of Language,” published in an edited volume, Disinvention and Reconstituting Language (Multilingual Matters, 2007).
