Felix Ritzkowsky

Felix Ritzkowsky is a Postdoctoral Researcher at the Center for Free-Electron Laser Science (CFEL) within DESY in Hamburg, Germany, where he works in the Attosecond Science Group under the DESY Photon Science Division. His current position, held since 2025, focuses on novel ultrafast imaging of molecules using strong-field lasers.

His educational trajectory includes:

• PhD in Petahertz Electronics and Source Development from DESY and the University of Hamburg (2018-2023)
• Master's thesis in Ultrafast Charge Transport on Nanostructures at the University of Konstanz (2016-2017)
• Bachelor's thesis in Compact Laser-Based Aerosol Detection at Andøya Space Center, Norway (2015)

Ritzkowsky's research centers on optical control of electron dynamics in condensed matter systems at femto-to-attosecond timescales, with specialized focus on artificial nanostructured materials. His work seeks to decode fundamental mechanisms governing ultrafast electron behavior to pioneer optical-frequency electronics (petahertz electronics). This integrates advanced strong-field laser techniques with nanoscale material engineering, bridging ultrafast spectroscopy, quantum electronics, and nanophotonics.

His key recognition includes:

• Feodor-Lynen Fellowship (2024-2025) at MIT hosted by Professors Erich Ippen and Phillip Keathley for petahertz bandwidth field-resolved spectroscopy research

No advisory roles or grant leadership are documented in available records, though his research is institutionally supported through DESY positions and MIT collaborations. He actively contributes to the ATTO Team's mission in molecular and ultrafast science, leveraging DESY's advanced laser infrastructure for cutting-edge electron dynamics studies.
