Research Scientist
About The Position
The Department of Physics and the Integrated Space Science and Technology Institute (ISSTI) in the College of Arts and Sciences at American University, in partnership with NASA's Goddard Space Flight Center (GSFC), invite applications for a Research Scientist position in integrated photonics, funded by a cooperative agreement between the two institutions. The appointment is a 12-month term position, with the possibility of renewal based on performance and the continued availability of external funding. The successful applicant will join the AURORA (Atmospheric Ultra-High Resolution Optical and Radio-frequency) Pathfinder, a technology demonstration project funded by NASA's Earth Science Technology Office (ESTO). AURORA is developing a millimeter-wave hyperspectral radiometer and advancing it to Technology Readiness Level (TRL) 6, with the goal of producing a flight-qualified instrument suitable for spacecraft integration in support of Planetary Boundary Layer (PBL) observations. The instrument is a highly sensitive, heterodyne-based spectrometer built on Photonic Integrated Circuits (PICs), incorporating electro-optical modulators, waveguide gratings, optical amplifiers, and photodetectors. The Research Scientist will contribute to the end-to-end engineering lifecycle of the AURORA photonic system. Principal responsibilities include: Architectural design, layout, and component-level development of Photonic Integrated Circuits, supported by circuit, subsystem, and microwave-photonic modeling; Hardware validation spanning chip-level and module-level photonic testing, full photonic system characterization, and instrument-level integration of the photonic subsystem; Systems engineering, including defining system requirements, generating interface documents, and specifying parts and Ground Support Equipment (GSE) for procurement; Laboratory operations, including maintaining and developing lab infrastructure with an emphasis on equipment automation; Documenting technical work, tracking project progress, and communicating outcomes through formal written reports and oral presentations. The successful applicant will work primarily on site at NASA Goddard Space Flight Center in Greenbelt, MD, which will provide the office and laboratory space needed for the project. The research is carried out with Dr. Mark Stephen (Project Development Lead, GSFC Climate and Radiation Laboratory) and Dr. Berhanu Bulcha (Instrument System Engineer, GSFC). The appointee will have opportunities to mentor or work with AU research students, to explore collaborations with other AU researchers, to present research seminars, and to participate in Department of Physics and ISSTI activities.
