- Principal Investigator: Karl Gordon, STScI
| Karl Gordon is an Assistant Astronomer at Space Telescope Science
Institute. His main scientific research interests are in the field of
interstellar dust, including the observational properties of dust grains
(eg., extinction curves, Extended Red Emission, and infrared dust
emission) and radiative transfer in dusty systems (eg., reflection
nebulae and galaxies). The Magellanic Clouds are obvious bridges between
work on Milky Way dust and dust in other galaxies. He is the PI of the
SAGE-SMC team. Functionally, he helps with the MIPS reductions and
point source creation for SAGE-LMC and SAGE-SMC and leads the reduction
of the MIPS SED data and IRS extended source data for SAGE-Spec.

project. She is an Associate Astronomer at Space Telescope
Science Institute where she supports the James Webb Space
Telescope (JWST) project. She is a member of the science

study how metallicity influences the early stages of formation of stellar
embryos, in particular in terms of their dust and organic chemistry. This in
turn will allow a better understanding of star formation in the early,
metal-poor Universe.
