Author/(co-)editor of 27 books; author of 90+ published and forthcoming articles and book chapters; translator of 11 books and of 90+ articles; some of his work has been translated into 7 languages; adviser and external reader of doctoral dissertations on both sides of the Atlantic.
His (co-)edited volumes as well as his translations of 70+ authors from dozens of countries have attempted to gather both established and fresh voices from different philosophical, artistic, and cultural traditions.
In December 2024, he published a monograph about the Austrian writer Peter Handke (who received the Nobel Prize for literature in 2019) entitled Peter Handkes literarische Romantik.
In December 2025, he published an edited volume (together with Michael Zangerl) entitled Alain Badiou und die Künste examining - for the first time in a comprehensive fashion - the question of the arts (literature and theater; music; painting) in the work of Alain Badiou, one of the most important and widely discussed contemporary European philosophers, and it includes a previously unpublished contribution by Alain Badiou on the status of "work" in the arts. This volume succeeds recently published volumes on Slavoj Zizek und die Künste (containing an essay by Slavoj Žižek) and on Jacques Rancière und die Literatur (edited with M. Manfé).
Currently, he is completing a volume (together with Gerhard Unterthurner and Christian Sorace) that examines contemporary constellations of biopolitics, aesthetics, and art through different theoretical and artistic perspectives from and/or on China, Japan, Turkey, Australia, Brazil, Russia, Italy, France, Austria, and Germany. Publication is expected in the fall of 2026.
His current research - facilitated by two guest professorships in 2025-26 - engages with the Austrian writer Elfriede Jelinek (who received the Nobel Prize for literature in 2004) to examine the ways in which Jelinek's (conception of) literature can be read in terms of the disarticulation of the romantic phantasmagoria of "große Kunst/Dichtung" that, particularly in the German and Austrian traditions, has repeatedly figured as the foundation for nationalist and exclusionary political projects. Texts such as Wolken.Heim, Totenauberg and several others engage with Martin Heidegger's questionable rendition of the relationship between language, Dichtung (as Ur-Sprache des deutschen Volkes), earth, and politics and perform Überschreibungen that exhibit elective affinities to both critical and deconstructive philosophical readings of Heidegger such as Theodor W. Adorno's Jargon der Eigentlichkeit and "Parataxis", Jacques Derrida's Geschlecht III and Philippe Lacoue-Labarthe's reflections of the relationship between romanticism and national-aestheticism. Incidentally, Jelinek's brilliant Überschreibungen of Heidegger's "erdiges" mytheme of language inscribe themselves into a long tradition of Heidegger criticism articulated by poets and writers such as Thomas Mann, Günter Grass, Arno Schmidt, Samuel Beckett, Maurice Blanchot, Ingeborg Bachmann, Paul Celan, Ernst Jandl, Friederike Mayröcker, Peter Handke, and Thomas Bernhard; they are also important responses to past and some current retrograde Heideggerian "scholarship" (on both earth and language) that exhibits a tendency to weißwaschen Heideggerian identitarian Sprach- and Bodendenken by disavowing and rendering concealed the mountains of bones and skulls piercing through the surface of the beautified Austrian (and German) landscapes - landscapes visited by Denker to provide their, as Jelinek would pun, Ur-sagen und Ur-kundenforschung with faux lived experience. Publication date is expected for 2027.
Another volume in progress (co-edited with Michael Zangerl) focuses on the work of the eminent French thinker Philippe Lacoue-Labarthe. It will examine Lacoue-Labarthe's significant contributions to poetry, the arts, psychoanalysis, and politics.
Some of his shorter texts (recently completed or in progress) address the following topics: the constellation of the museum, the avant-garde and biopolitics in the aesthetic writings of Boris Groys and Jacques Rancière; Mario Perniola's aesthetic thought; decolonial receptions of Frantz Fanon's work in Germany and elsewhere.
