Since the Peaceful Revolution nonviolently toppled the Berlin Wall and Communism in the German Democratic Republic in 1989, Grünbein has traveled widely in Europe, South-West Asia, and North America, and sojourned in various places, including Amsterdam, Paris, London, Vienna, Toronto, Los Angeles, New York City, and St. Louis.

He has translated classic texts from Aeschylus and Seneca, and a variety of authors, including John Ashbery, Samuel Beckett, Wallace Stevens, Henri Michaux, and Tomas Venclova.

[6] He has been a regular contributor to Frau und Hund – Zeitschrift für kursives Denken, edited by the academy's rector, the painter Markus Lüpertz.

[12] Conceiving poetry as a means of memorial, historical, and aesthetic exploration, Grünbein arguably, draws not only on his biography, but on a deep sense of history and far-ranging erudition to produce sardonic poems and essays, bristling with unusual perceptions and inventive expressions".

"As in his poetry, in his essays, too", observes Michael Eskin, "Grünbein succeeds in artfully interweaving autobiography and memoir with a host of broader concerns ranging from questions of history, science, and medicine, to question of ethics, aesthetics, and politics, with special attention to the continued relevance of the past – Greek and roman antiquity in particular – in and to the contemporary world, as well as the inevitable interpretive malleability of the past in the light of our ever-evolving present".

[15] Grünbein's works on Descartes' philosophy and its significance for the poetic subjectivity have been praised by prominent critics and thinkers for their depth and remarkable style, "one capable of conducting powerful and original thought with no loss of lyric intensity", notices Don Paterson.
