Kjetil Dohlen

Dr K. Dohlen was awarded the PhD in Applied Optics at Imperial College, University of London, for his work on static
Fourier transform spectrometers in 1994. As a post-doctoral researcher at Aerospatiale in Cannes, France, he was then
involved with modelling of the instrument function of the IASI instrument, a thermal infrared satellite-borne Fourier
transform spectrometer for next-generation meteorological observations. He gained further experience with
instrumentation for space astronomy when he obtained a Fellowship of the European Space Agency at the Laboratoire
d'Astronomie Spatiale (LAS) in Marseilles, France. There he was primarily concerned with the optical design of the
narrow-angle camera (Osiris-NAC) for the Rosetta cometary mission. In 1996 he obtained a permanent position at the
Observatory of Marseilles, recently merged with LAS to form the Laboratoire d’Astrophysique de Marseille, LAM.

Apart from being responsible for the optical design for the Rosetta NAC (ESA) and the Herschel SPIRE (ESA) instruments, Dr. Dohlen has been involved in several instrument proposals, notably for HST-2002, NGST and TPF. He also participated in the French proposal for a CFHT replacement. He is currently involved in the Alcatel Phase A study for the NGST-NIRSPEC multi-object spectrograph and is part of the Boeing-SVS TPF study. He also has administrative duties within his institutes where he ensures the co-ordination of the Secteur Optique.
