OVERVIEW

INTRODUCTION
The Smithsonian Astrophysical Observatory (SAO) is at the forefront, internationally, of the scientific exploration of the universe. SAO combines its resources with those of the Harvard College Observatory to form the Harvard-Smithsonian Center for Astrophysics (CfA). The CfA is the best-known astrophysics center in the world. Its programs range from ground-based astronomy and astrophysics research to space-based research, the engineering and development of major scientific instrumentation for space launch and use in large ground-based facilities, and research designed to improve science education. The research objectives of SAO are carried out primarily with the support of Government and Smithsonian Institution funds, with additional philanthropic support. Government funds are in the form of Federal appropriations or the form of contracts and grants from other agencies. In contrast, Institution funds are available to SAO through grants from the Institution's Restricted Funds, Special Purpose Funds, Bureau Activities, Business Activities, and non-Federal contracts and grants.

SUMMARY
This is the position of Astrophysicist (Post-Doctoral Research Fellow) in the Optical and Infrared (OIR) Division. The purpose of this position is to train postdoctoral researchers to conceive, plan and conduct highly specialized research in the incumbent's area of expertise. The incumbent will be expected to perform scholarly research and participate in making contributions to the field of physical science

MAJOR DUTIES

1. Conduct a program of research and scholarship related to stellar parameterization with the Roman Space Telescope under the supervision and direction of the Principal Investigator.

2. Assists in the development of software and analysis pipelines for modeling stellar photometry and astrometry with Roman and complementary surveys.

3. Engage in the dissemination of the results of the research in which engaged, for example prepare papers for publication in scientific journals, develop and release open-source software, and present findings at scientific meetings, as required.

4. Engage in the wider research and scholarly activities of your research group and the CfA more broadly.

5. Mentor and assist, as appropriate and as directed, graduate and undergraduate students in your area of research.

QUALIFICATION REQUIREMENTS

Basic Requirements:
