Following his dissertation, which had already explored phenomena at the intersection of art, politics, and philosophy, Avanessian focused on developing a new approach in literary theory and philosophy of language. Collaborating with colleagues such as Anke Hennig, he began working in 2011 on connecting new speculative-ontological approaches with twentieth-century philosophies of language, which resulted most notably in two co-written books, 'Present Tense: A Poetics' (2012, English translation 2015) and 'Metanoia: A Speculative Ontology of Language, Thinking, and the Brain' (2014, English translation forthcoming 2016). Moreover, he played a central role in bringing accelerationism into German-language political philosophy.
