معرفی
Steven Johnson is a Full Professor of Physics at ETH Zurich and heads the Institute for Quantum Electronics. He holds a joint appointment at the Paul Scherrer Institute (PSI), leading the experimental laser group at the SwissFEL x-ray free-electron laser. He earned a BSc in Mathematics and Physics from Harvey Mudd College (1997) and a PhD in Physics from UC Berkeley (2002). His research focuses on atomic-scale dynamics in materials, leveraging light-matter interactions, ultrafast laser techniques, and x-ray methods to study condensed matter systems. He has pioneered work on coherent vibrational excitations, THz-driven spin dynamics, and structural phase transitions. Johnson’s contributions include advancing femtosecond x-ray diffraction and developing novel experimental tools for probing material behavior at ultrafast timescales.
- Education: BSc (Harvey Mudd College, 1997), PhD (UC Berkeley, 2002)
- Affiliations: ETH Zurich (since 2020), PSI (since 2003), SwissFEL collaboration
- Roles: Head of PSI’s Pump Laser Group, Member of ETH Zurich’s Physics Department Strategy Commission
His honors include the Advanced Light Source Doctoral Fellowship (2001) and NSF Graduate Fellowship (1997). He collaborates internationally with institutions like SLAC and Vanderbilt University, focusing on multiferroics and ultrafast magnetism. His group’s work integrates laser systems at SwissFEL to enable cutting-edge pump-probe experiments across biology, chemistry, and physics.
