Dr. Blavier first joined the JPL-MkIV Team in August 1985 as a contractor from Ball Aerospace. He participated in the MkIV campaigns in McMurdo, Antarctica (ground-based) and from Punta Arenas, Chile (NASA DC-8). In late 1987, he started graduate work with Profs. Delbouille and Dubois at the University of Liège, Belgium: his research tasks included installing the Fourier transform spectrometers at the International Scientific Station of the Jungfraujoch (Switzerland) for atmospheric measurements, and at the Institute of Astrophysics in Liège for laboratory measurements. He was hired by JPL in August 1990 as MkIV cognizant engineer, and participated in all the MkIV campaigns since then (one DC-8 campaign, 24 balloon campaigns). Dr. J.-F. Blavier obtained his Ph.D. in Physics from the University of Liège in July 1998.
