Roel Dieltiens studied in Antwerp and Detmold. From the very beginning of his career, his forceful personality and unconventional approach won him engagements in major international venues. He has also won international fame as a chamber musician and as the founder of the Ensemble Explorations. Since 2010, he has performed in a trio with the fortepianist Andreas Staier and the violinist Daniel Sepec. His many recordings for the Harmonia Mundi and Etcetera labels have been acclaimed by the press and the public. In 2010, Dieltiens was awarded a Klara prize and the Caecilia Prize for his recording of the Suites for solo cello by J. S. Bach. While most of his activity is devoted to the baroque and classical repertoires on period instruments, he also plays the modern cello. He has successfully tackled the Romantic repertoire (Mendelssohn and Brahms) and the modern repertoire (in particular, Kodály and Martinù). His curiosity has led him to revive neglected music by, for example, Servais and Franchomme. He is a professor at the Hochschule der Künste in Zurich and at the Lemmensinstituut in Leuven. He has served on the jury of a variety of international competitions (including the Bach Competition in Leipzig and the Tchaikovsky Competition in Moscow).
