Job Description

Applications are invited for a Postdoctoral Fellow position at the Center for Astrophysical Sciences of Johns Hopkins University. The successful candidate will work with Professor Ray Jayawardhana and his collaborators on observational studies of extra-solar planets and/or sub-stellar objects. Candidates with expertise and interests in ground-based high-resolution exoplanet spectroscopy and/or low-resolution spectroscopy of exoplanets and planetary-mass brown dwarfs with the James Webb Space Telescope (JWST) are particularly encouraged to apply.

Group members lead the on-going ExoGemS Large Program at the Gemini Observatory targeting 30+ planets that span a wide range of properties. Prof. Jayawardhana is also a member of the JWST/NIRISS science team, with ~200 hours of GTO dedicated to exoplanet characterization. In addition, with Drs. Aleks Scholz and Koraljka Muzic, he co-leads a ~20-hour JWST/NIRISS GTO program focused on the lowest-mass free-floating sub-stellar objects. Group members also use data from TESS, Kepler, CHEOPS, Subaru, Keck, VLT, CFHT, and other major observatories.

The position is for two years, with extension to a third year possible, and comes with a competitive salary and funds for research expenses. Start date is flexible, ideally between July-December 2024. The JHU Center for Astrophysical Sciences and the adjacent Space Telescope Science Institute form a large and lively astrophysical community.

Applicants should send their curriculum vitae, a description of research interests and plans and a list of publications, and should arrange for three letters of recommendation to be sent electronically to Applications are accepted until the position is filled, and those received before March 1, 2024 will receive full consideration.
