Postdoctoral Research position: Novel ultrafast imaging of molecules with strong-field lasers

Research
My research focuses on the optical control of electron dynamics in condensed matter on the femto-to-attosecond timescale, with a particular focus on artificial nano structured systems. By uncovering the relevant mechanisms governing the electron dynamics on these extreme timescales, I aim to pave the way towards electronics operating at optical frequencies.
