Mark Keller (Fed)
Physicist
Mark Keller is a physicist in the Quantum Sensors Group of the Quantum Electromagnetics Division in Boulder. He has worked in several areas at NIST since arriving as a postdoc in 1995. These include single-electron tunneling devices, fundamental electrical metrology, graphene device fabrication, and measurement of spin-torque and spin-orbit-torque effects in magnetic multilayers. His current work involves superconducting transition-edge sensors for detection of gamma-rays. He helped deliver a gamma-ray spectrometer to Idaho National Laboratory in 2022 and is working on a similar instrument for delivery to Pacific Northwest National Laboratory in 2024.
