Anne L’Huillier is a Professor of Atomic Physics at Lund University in Sweden, where she leads the Attosecond Physics research group. Her research, which is both experimental and theoretical in nature, concerns the development of attosecond sources of radiation and the use of such radiation for the study of ultrafast electron dynamics. She has received numerous awards for her internationally acclaimed work, and most recently in 2023 she became the fifth woman to be awarded the Nobel Prize in Physics along with Pierre Agostini and Ferenc Krausz. Having presented a plenary at Physics Days 2021, she now returns to give a lecture making her groundbreaking work accessible to the public.
