Dr. Dag Winkler

Biography

Dag Winkler received his PhD in Physics from Chalmers University of Technology in 1987. He spent two years as a research associate at Yale University from 1988 to 1990. In 1993, he became a docent at Chalmers and was appointed professor of physics in 2000. He has been affiliated with Gothenburg University and appointed as a professor in Quantum Device Physics at Chalmers University of Technology in 2003. Winkler's main research focuses on tunneling superconductors and superconducting electronics, including developments in SIS (Superconductor-Insulator-Superconductor) heterostructures, Hot Electron Bolometers (HEB), high-frequency mixers, and Josephson flux-flow oscillators within the THz range. He also explores applications of SQUIDs (Superconducting Quantum Interference Devices) for low-level measurements. His current research activities delve into multifunctional materials and interfaces, high-temperature superconductors, as well as 2D electronic properties at interfaces such as LaAl2O3 and SrTiO3. He investigates intrinsic Josephson effects in single crystal Bi2212 and applies HTS SQUIDs in magnetoencephalography (MEG) and Ultra Low Field Magnetic Resonance Imaging (ULF-MRI). Winkler has significant experience in microwave technology, low-temperature physics, and cryogenic systems. He also worked at ABB Corporate Research, focusing on cryogenic high-voltage cables and low-level measurements using superconducting electronics from 1999 to 2003, and engaged with the Imego Institute (now Acreo) in developing magnetic sensor systems utilizing microwave technology.
