Job Announcement Text: 

The Space Telescope Science Institute (STScI) invites applications for one or more postdoctoral positions to work with Drs. Julia Roman-Duval and Erik Tollerud, and collaborators. The successful applicant(s) will work on either (or both) of two HST UV spectroscopic programs: the METAL-Z project with Dr. Julia Roman-Duval and on the COS-SAGA program with Dr. Erik Tollerud. METAL-Z is a large Cycle 27 HST program that will obtain COS FUV spectra toward massives stars in the low-metallicity galaxies IC 1613 and Sextans A. The goal of the program is to measure interstellar depletions and to characterize the lifecycle of metals in neutral gas and dust at low metallicity, thus providing the depletion calibrations required to understand the chemical enrichment of the Universe through damped Lyman-alpha systems (DLAs). The COS-SAGA program will obtain HST FUV spectroscopy of QSOs around nearby Milky Way-like galaxies, to characterize both the gaseous and dark matter halos of these galaxies and their satellite systems. These galaxies are from the SAGA Survey, a project to characterize the satellite systems of 100 Local Group analogs by combining these observations with galaxy formation simulations. COS-SAGA therefore includes a simulation component. The successful applicant(s) will work on the measurements and/or scientific analysis of either or both projects. Independent research in related areas will be encouraged and supported (up to a 50% level) pending satisfactory progress.

The successful applicant(s) will work closely as part of the dynamic, welcoming, and inclusive ISM@STSCI group that includes Drs. Martha Boyer, Karoline Gilbert, Karl Gordon, Joshua Peek, and a number of postdocs and graduate students. The ISM@ST group has broad scientific interests centered on the interstellar medium, from dust producing stars to the gas and dust in the interstellar and circum-galactic medium. This research will involve working with and, if possible, proposing for observations with Hubble, JWST, and ground-based facilities.

The successful applicant(s) will benefit from the career mentoring program at STScI, interactions with the Johns Hopkins University research staff, and a stimulating work environment rich in colloquia, journal clubs, symposia, and learning opportunities related to the missions supported by STScI (HST, JWST, WFIRST).

Applicants must hold a Ph.D. degree in Astronomy, Physics, Planetary Science, or related fields at the start of the post-doctoral researcher position. Research experience in the areas of gas-phase abundances, spectroscopy, nearby galaxies, interstellar and/or circumgalactic gas and dust is desirable. Expertise in numerical methods, statistics, and/or comparing observations to numerical simulations is a plus.

The positions are for two years, with a possible renewal for a third year, depending on performance and availability of funding. The nominal start date is summer/fall 2020 but earlier start dates are possible. STScI, located on Johns Hopkins University Campus in Baltimore, Maryland, offers an excellent benefit package (including comprehensive healthcare and paid parental leave), competitive salaries, and a stimulating work environment. STScI’s pay for postdoctoral researchers is commensurate to the year of Ph.D. We especially welcome applications from women, minorities, veterans, LBGTQ+ people, and other members of underrepresented groups.

Prospective applicants should complete an on-line application through:

The following materials are requested in a single PDF file: a brief cover letter detailing your research interests and relevant expertise, a curriculum vitae, a list of publications, and a summary of previous and current research (limited to 3 pages). Complete applications received by December 2, 2019, will receive full consideration. Applicants should arrange for three confidential letters of reference to be submitted by December 9, 2019 via the online application system.

Questions regarding the application process can be sent directly to
