Charles Poteet

Postdoctoral Fellow

Charles Poteet is a Postdoctoral Fellow at STScI. He is interested in understanding the physical processes responsible for shaping our Solar System and the nature of pre-planetary matter, the building blocks of planets. He has extensive experience in infrared spectroscopy using the Spitzer Space Telescope, in modeling silicate dust and ice absorption features, and in studying the evolution of these materials in both the interstellar medium and environments of active star formation. He is also an expert in image processing and analysis methods for high-contrast coronagraphic observations (in both total and polarized scattered light) of circumstellar disks to characterize the dust and morphological properties of these systems.
