Dag Winkler received his PhD in Physics at Chalmers in 1987, and spent two years as research associate at Yale University from 1988 to 1990. He became docent in 1993 at Chalmers and professor in 2000 at Gothenburg University. In 2003 he was appointed professor in physics at Chalmers University of Technology. His main research is tunneling in superconductors and superconducting electronics, such as SIS (Superconductor-Insulator-Superconductor) and HEB (Hot Electron Bolometer) high frequency mixers and Josephson flux-flow oscillators for the THz-range, SQUIDs (Superconducting QUantum Interference Device) and applications at low level measurements. His current research activities include multifunctional materials and their interfaces, such as high temperature superconductors (HTS) and related perovskites, the 2D electronic properties at interfaces between LaAl2O3 and SrTiO3, intrinsic Josephson effects in single crystal Bi2212, and HTS SQUIDs for MEG (magnetoencephalography) and ULF-MRI (Ultra Low Field Magnetic Resonance Imaging). He has long experience in microwave technology, low temperature physics, and cryogenic systems. Part time he worked at ABB Corporate Research on development of cryogenic high voltage cables and low-level measurements using superconducting electronics. From 1999 to 2003, he was also engaged at the Imego Institute (now Acreo), building up an activity on magnetic sensor systems and microwave technology. During 2006 to 2007 he was the head of the Quantum Device Physics Laboratory. During the period June 1, 2007 to June 30, 2016 he was head of the Department of Microtechnology and Nanoscience – MC2, at Chalmers University of Technology.
