Biography

Tielens has contributed significantly to several fields of astronomy, including interstellar physics and astrochemistry.[2] He is mostly known for his work on large aromatic molecules (PAHs) in space[3] and on photodissociation regions.[4] He is also the author of a reference textbook on the interstellar medium.[5]

Tielens is the project scientist of the HIFI instrument on board of the Herschel Space Observatory. He used to be the NASA Project Scientist of the Stratospheric Observatory for Infrared Astronomy.

Since 2012 Tielens has been a member of the Royal Netherlands Academy of Arts and Sciences.[6]
