Kay Justtanont
Kay's research is centered on studying dust and gas around evolved late-type (so-called AGB) stars. Much of Kay's work involves modelling ground-based observations as well as data from various astronomical space missions. Kay is also interested in dust in star forming region and outflows from young stellar objects.
Kay is currently working on the mid-infrared instrument (MIRI) as Swedish PI. MIRI is one of the four instruments which will fly aboard the James Webb Space telescope (JWST) due to be launched in 2018.
