Post-Doctoral Research In Modeling Accretion On To Black Hole Binaries

The Space Telescope Science Institute (STScI), is operated by the Association of Universities for Research in Astronomy (AURA). STScI is NASA's science operations center for missions including the Hubble and James Webb Space Telescopes.

The Space Telescope Science Institute invites applications for a post-doctoral researcher position to work on analytical and numerical modeling of accretion in supermassive black hole binary systems with Dr. Daniel J. D'Orazio and collaborators, including Drs. Emanuele Berti, Alessandra Corsi, Paul Duffell, and Christopher Tiede. This work aims to extend numerical modeling of circumbinary accretion to new physical regimes and analyze resulting orbital evolution and multi-messenger signatures of binary accretion in preparation for upcoming observations with Rubin, Roman, LISA and the Pulsar Timing Arrays. Part of the time may be available for independent research or new projects in related areas. The nominal start date is expected to be in Summer/Fall 2026, but other dates are negotiable. The initial appointment is for two years, with an expected renewal to a 3rd year subject to satisfactory performance and availability of funding.

STScI offers a dynamic, supportive, and inclusive research environment with journal clubs, science talks, and a postdoc mentoring program. STScI is located on Johns Hopkins University Campus in Baltimore, Maryland, and there are ample opportunities to interact with the JHU scientific community, as well as researchers in the broader Maryland area (e.g., University of Maryland, NASA Goddard). STScI offers an excellent benefits package, competitive salaries, and a stimulating work environment. STScI's pay is commensurate to the year of Ph.D.

The successful candidate will join Dr. D'Orazio's research group which interacts regularly with research groups at JHU working on a wide array of topics in general relativity and multi-messenger astrophysics. High Performance CPU and GPU Computing resources will be available locally and through NASA High End Computing Capability.

Any questions about the position should be directed to dorazio@ststci.edu.

Applicants shall hold a Ph.D. degree in Astronomy, Physics, or related fields at the start of the position. Expertise in one or more of the following areas is desirable: (a) Numerical hydrodynamics and experience with high performance computing; (b) Accretion physics; (c) Orbital dynamics; (d) Black hole astrophysics; (e) Radiative transfer; (f) Gravitational lensing and General Relativity. More important is the willingness to take on new projects, learn new skills, and work independently to bring these projects to fruition.

The following materials will be requested in PDF format:

• cover letter
• curriculum vitae, including a list of publications
• 1-3 page statement of research interests, accomplishments, and relevant technical experience.

Applicants are requested to complete an on-line application through: https://stsci.slideroom.com/#/permalink/program/87755

Complete applications received by January 30, 2026, will receive full consideration. Also, applicants must arrange for three confidential letters of reference. Reference letters must be submitted by the same date via the on-line application system. Reference #: 0015526
