The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or an affiliated research institute. These fellowships are 1-3 years. They are competitive and designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology. Circumstellar disks are an integral component of planetary systems. They provide the raw material and host environment for planet formation, and persist into mature planetary systems as debris from ongoing collisions of remnant planetesimals. Their internal structure can show the dynamic imprint of any planets within. We are conducting observational research on circumstellar disks with the goals of imaging new systems; understanding their structure, dust properties, and evolution via multi‑wavelength observations; and searching for associated planets. Recent imaging data from the Hubble Space Telescope, James Webb Space Telescope, and the Atacama Large Millimeter Array, combined with infrared spectral energy distributions from the Spitzer Space Telescope and Herschel Space Observatory, are compared with numerical models to derive disk properties. Supporting data is obtained with large ground‑based telescopes such as Keck and Palomar. Related research includes preparatory work for disk imaging with the coronagraph instrument on the Roman Space Telescope, scheduled for launch by spring 2027. Working with the Roman Coronagraph Community Participation team, we are modeling the likely size and brightness of never‑before‑imaged debris disks around bright stars. The goal of this work is to support target selection for community surveys of warm debris disks and exozodical dust with the Roman Coronagraph, followed by development of observing sequences for execution during the first few years of the mission. Additional related research is being conducted on performance goals and technology issues for the future Habitable Worlds Observatory, and updates & improvements to the website https://circumstellardisks.org. JPL has a dynamic environment for exoplanet research with NASA's Exoplanet Exploration Program Office, JPL's Exoplanet Discovery and Science research group, the Roman Coronagraph Instrument team, access to the Palomar 5 m telescope, and collaborations with local exoplanet researchers at the Caltech Astronomy Department and the NASA Exoplanet Science Institute. Candidates with interests in protoplanetary and debris disks, exoplanet direct imaging, or high‑contrast observation techniques are encouraged to apply. Location
