The successful applicant will work with Dr. Karoline Gilbert on chemical and dynamical studies of stars in the Local Group.  The main project will be the analysis of a large, resolved stellar spectroscopic survey of M33.  As the only dwarf spiral galaxy in the Local Group, M33 provides a unique opportunity to study the resolved stellar dynamics and abundance gradients of a low-mass, star-forming spiral galaxy, and to investigate the stability of low-mass disks.  M33’s disk has also been surveyed extensively by other facilities, including contiguous Hubble Space Telescope imaging from the ultraviolet through the infrared and observations of HI and Hα with Arecibo and the VLA.  These provide a wealth of ancillary datasets that can be utilized in interpreting the Keck/DEIMOS spectroscopic observations, including comparisons between the kinematics of the stars, ionized, neutral, and molecular gas.

This position will include collaboration with members of the M33 spectroscopic project, especially Prof. Puragra Guhathakurta (University of California Santa Cruz) and Dr. Erik Tollerud [Space Telescope Science Institute (STScI)], and will provide opportunities to collaborate with members of the Panchromatic Hubble Andromeda Treasury Team and members of the ISM@STSCI group.  The dynamic, welcoming, and inclusive ISM@STSCI group (https://sites.google.com/view/ism-stsci/home) includes Drs. Martha Boyer, Karl Gordon, Joshua Peek, Julia Roman-Duval, and a number of postdocs and graduate students.   This research will involve working with and, if possible, proposing for observations with Hubble, JWST, and ground-based facilities. Independent research in related areas will be encouraged and supported up to the 50% level pending satisfactory progress on the main project.

The successful applicants will benefit from interactions with the Johns Hopkins University and STScI research staff, a career mentoring program at STScI, and a stimulating work environment rich in colloquia, journal clubs, and symposia, hosted through both JHU’s CAS and STScI.

Applicants must hold a Ph.D. degree in Astronomy, Physics, or a related field at the start of the post-doctoral researcher position.  Research experience in the areas of resolved stellar population analysis, dynamical analyses, or chemical abundance measurements is desirable.  Expertise in optical-NIR spectroscopy, numerical methods, statistics, or comparison of data with simulations, is a plus.

The position is for two years, with a possible renewal for a third year (subject to satisfactory performance and continued funding).  The nominal start date is summer/fall 2020 but earlier start dates are possible. A competitive benefits package is provided by Johns Hopkins University. We especially welcome applications from women, minorities, veterans, LBGTQ+ people, and other members of underrepresented groups.
