Baltimore, 3700 San Martin Drive, Baltimore, MD 21218, USA

The Space Telescope Science Institute (STScI) invites applications for a post‑doctoral researcher position to work with Dr. Leonardo dos Santos and Dr. Joshua Lothringer on observational studies of atmospheres of hot, gas‑giant exoplanets, specifically the properties of their upper atmospheres and a detailed study of the lower atmosphere of the hottest known exoplanet. This research will include analysis and interpretation of UV observations with the STIS instrument on the Hubble Space Telescope (HST) and near‑IR observations with the NIRISS instrument on the James Webb Space Telescope (JWST).

Part of the time may be available for independent research or new projects in related areas. The nominal start date is flexible, but it can start as early as October 2026. The initial appointment is for two years, with an expected renewal to a third year subject to satisfactory performance and availability of funding.

• Conduct observational studies of atmospheres of hot, gas‑giant exoplanets.
• Analyze and interpret UV observations with STIS on HST and near‑IR observations with NIRISS on JWST.
• Collaborate with Dr. Leonardo dos Santos and Dr. Joshua Lothringer on research projects.
• Possibly develop independent research or new projects in related areas.
• Work within the Transiting Exoplanets Research group and engage with related groups at JHU.

• Ph.D. in Astronomy, Physics, Planetary Science, or related field required at the start of the position.
• Expertise in UV/near‑IR spectroscopy, data reduction and instrumental systematics of space‑based observations, exoplanet transits/eclipses/phase curves, or atmospheric escape is desirable.
• Creativity, willingness to take on new projects, learn new skills, and work independently.

• Brief cover letter, curriculum vitae, list of publications, and a 1‑3 page statement of research interests, accomplishments, and relevant technical experience.
• Three confidential letters of reference.
• Applications received by August 31, 2026.
