Mathieu Taupin is a permanent researcher at LNE. He obtained his PhD in 2013 from CEA Grenoble, working on unconventional superconductivity in strongly correlated materials. He then joined the Aalto university in Finland to work on single electron transistors based on superconducting quantum dots. In 2015, he moved to Vienna University of Technology as university assistant, mainly to work on correlated materials. Since 2022, he is working at LNE on quantum Hall resistance metrology in the Fundamental electrical metrology department.
