• Research proposal
• Three letters of recommendation
• Official doctoral transcript documents

Application Deadline11/1/2025 6:00:59 PM Eastern Time ZoneDescriptionAbout the NASA Postdoctoral ProgramThe 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 at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA's missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.Description: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 multiwavelength

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 groundbased 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

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 5m 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.
