Brendan McCullian (Fed)
Physicist
Brendan is a Physicist in the Nanoscale Spectroscopy Group in the Nanoscale Device Characterization Division of the Physical Measurement Laboratory (PML) at the National Institute of Standards and Technology (NIST). He joined NIST in 2024. Brendan works on characterization and development of technology based on color centers in wide bandgap semiconductors. Applications include quantum single photon emission for quantum networking and advancing sensing metrology. Brendan’s focus is on improving device performance and fabrication with an eye toward scalability, robustness, and sensitivity.
Brendan received a B.S. (2014) in physics from Pennsylvania State University and an M.S. (2017) and Ph.D. (2020) in physics from The Ohio State University. While at Ohio State he developed new modalities for sensing thin film magnetization dynamics using nitrogen-vacancy defects in diamond. During his postdoctoral appointment at Cornell University, Brendan worked on characterizing noise and engineering stability of the low-temperature optical transitions of diamond nitrogen-vacancy defects for quantum networking applications.
Brendan’s general research interests include:
- Spin, optical, and related properties of defects in wide bandgap semiconductors
- Advancing metrology for defect-based devices
- Unconventional quantum control and readout schemes
- Thin film magnetization dynamics
