Postdoctoral Scholar - Auroral and Subauroral Optical Phenomena - Space Sciences Laboratory

The Space Sciences Laboratory (SSL) at the University of California, Berkeley, seeks applicants for a Postdoctoral Scholar who will be working with Dr. L Claire Gasque and Dr. Brian Harding, specializing in auroral and subauroral optical phenomena. SSL has a long history of developing and operating space instruments and missions and of using ground-based and space-based observations, numerical models, and scientific software to advance understanding of the space environment. The postdoctoral scholar will join a collaborative geospace research group at SSL broadly investigating magnetosphere-ionosphere-thermosphere coupling. The postdoctoral research will examine how ionospheric currents and electric fields affect conductivity, chemistry, and energy deposition, and how optical phenomena such as enhanced aurora, Strong Thermal Emission Velocity Enhancement (STEVE), and the picket fence may be used to trace these processes. The work combines ground-based optical measurements, satellite observations, and physics-based numerical modeling. The postdoctoral scholar will conduct original research on the physical processes governing auroral and subauroral magnetosphere-ionosphere-thermosphere coupling. The scholar will work across two complementary NASA Living With a Star projects and will be encouraged to take intellectual ownership of one or more research components based on their interests and expertise. Specific responsibilities may include: Analyze ground-based optical observations from auroral imagers and spectrographs, including data from the Transition Region Explorer (TREx) network. Develop and apply methods to identify and characterize auroral and aurora-like phenomena Construct and analyze event catalogs and identify conjunctions between ground-based and satellite observations Analyze satellite measurements from missions such as Swarm and DMSP to characterize relevant background plasma conditions, field-aligned currents, electric fields, and particle precipitation Develop, adapt, or apply kinetic, chemical, and electrodynamic models of ionosphere-thermosphere coupling under exteme driving to characterize electron energy distributions, conductivity, and optical emissions. Develop synthetic optical observations and perform quantitative comparisons between model results and ground-based or satellite measurements. Develop well-documented scientific software and reproducible analysis tools, and contribute research software and derived data products to public repositories. Lead and contribute to peer-reviewed publications and present results at scientific conferences and LWS team meetings Collaborate with members of the two project teams and the broader NASA Living With a Star Focused Science Team. Participate in the mentoring of undergraduate or graduate researchers, as appropriate, such as through the SSL ASSURE summer REU program PhD (or equivalent international degree) or enrolled in a PhD (or equivalent international degree) program. #J-18808-Ljbffr University of California at Berkeley
