Cap-Exempt H-1B Position — No lottery required
Requisition Id 16491 **PDAA** **Overview:** We are seeking a Postdoctoral Research Associate who will focus on the LEGEND program’s search for neutrinoless double-beta decay of Ge-76. This position resides in the Neutrino Research Group in the Fundemental Nuclear & Particle Physics Section, Physics Division, Physical Sciences Directorate at Oak Ridge National Laboratory (ORNL). As part of our research team, you will play an active role in the search for neutrinoless double-beta decay of Ge-76 with the LEGEND-200 experiment, currently operating at LNGS, help lead the R&D, design, and implementation of the LEGEND-1000 experiment, and pursue R&D that extends the physics potential of low-background, rare-event searches. The successful candidate will work closely with a range of students, other postdoctoral fellows, scientific and engineering staff, visiting scholars, as well as a large network of international collaborators. Networking opportunities extend to the group’s broad research program in low-energy neutrino interactions at the SNS and HFIR, as well as research programs in fundamental symmetries and nuclear physics within the ORNL Physics Division. Further, ORNL supports an active postdoctoral program, which provides research support, professional development, and social activities. **Major Duties/Responsibilities:** - Assume a leading role in one or more of the group’s contributions to the LEGEND program: - Contribute to the LEGEND-200 data analysis and the development of advanced analysis routines - Contribute to the R&D on advanced instrumentation, design, and simulations of the next generation LEGEND-1000 experiment. - Develop new low-background materials, scintillators, and production techniques, including custom synthesis of PEN and clean additive manufacturing processes - Integrate AI/ML into experimental design, data analysis, and detector performance evaluation workflows - Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with o
