Abigail Wessels is an NRC postdoctoral research associate working in the Quantum Sensors Group. Her work focuses on improving superconducting transition edge sensor (TES) microcalorimeter technology. In graduate school her research focused on building a next generation gamma-ray TES spectrometer, as well as understanding the physics of noise processes in TESs. She now works on development of soft x-ray TESs for x-ray spectroscopy.
