Postdoctoral Research Associate - Physics

Position Summary The Astrophysics, Particle Astrophysics, and Space Sciences group of the Department of Physics at WashU in St. Louis invites applications for a postdoctoral position, for a negotiable start around September 6, 2026. The appointment is expected to be up to2 years with subsequent year-to-year extension depending on performance and funding. The postdoc will work in the group of Prof. Karthik Ramanathan, primarily on the development of novel superconducting detectors for particle physics applications. These include qubit-based detectors (QPDs/SQUATs) and Kinetic Inductance Detectors (KIDs). The project scope is expected to run the gamut from design to on-site nano-fabrication to device testing in the group's dilution refrigerator, along with analyzing collected data. There is scope for the postdoc to define their own additional sub-projects - e.g., developing new sub-eV energy calibration techniques - and also interface with a larger experimental collaboration.
