NASA Awards Postdoctoral Fellowships for 2022

For Release: March 25, 2022

NASA has selected 24 new Fellows for its prestigious NASA Hubble Fellowship Program (NHFP). The NHFP is one of the highlights of NASA's pursuit of excellence in astrophysics. The program enables outstanding postdoctoral scientists to pursue independent research in any area of NASA Astrophysics, using theory, observation, experimentation, or instrument development. Nearly 450 applicants vied for the 2022 fellowships. Each fellowship provides the awardee up to three years of support.

Once selected, Fellows are named to one of three sub-categories corresponding to three broad scientific questions NASA seeks to answer about the universe:

  • How does the universe work? — Einstein Fellows
  • How did we get here? — Hubble Fellows
  • Are we alone? — Sagan Fellows

"From the quest for the first galaxies to the hunt for habitable exoplanets, this year's NASA Hubble Fellows seek answers to some of the most critical questions about our universe," said Paul Hertz, Astrophysics Division director at NASA Headquarters in Washington, D.C. "This is an incredibly promising group of young scientists, and I can't wait to see where their research takes them from here."

The newly selected NHFP Fellows will begin their programs in the fall of 2022 at a university or research center of their choosing in the United States. The list below provides the names of the 2022 awardees, their fellowship host institutions, and their proposed research topics.

2022 NASA Hubble Fellowship Program:

  • Michael Wong, Carnegie Earth and Planets Laboratory, Assessing the Network Topologies of Planetary Atmospheres for Potential Biosignatures
  • Zhoujian Zhang, University of California Santa Cruz, Probing the Formation of Directly Imaged Exoplanets via Robust Atmospheric Characterization

An important part of the NHFP is the Symposia, which allow Fellows the opportunity to present results of their research, and to meet each other and the scientific and administrative staff who manage the program. A lively and very successful virtual symposium was held in the fall of 2021, and organizers are waiting to make a decision on whether the 2022 symposium will be virtual or in-person.

The Space Telescope Science Institute administers the NHFP on behalf of NASA, in collaboration with the Chandra X-ray Center at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, and the NASA Exoplanet Science Institute at Caltech/IPAC in Pasadena, California.
