Mette B. Gaarde

Mette B. Gaarde is a Danish atomic, molecular, and optical physicist and Boyd Professor at Louisiana State University who conducts theoretical and computational research on ultrafast laser-matter interactions.

Education and career Gaarde completed her undergraduate degree and Ph.D. at the University of Copenhagen, Denmark, graduating with the latter in 1997. Prior to joining Louisiana State University, she worked as a research assistant professor at Lund University in Sweden.

In 2003, Gaarde joined the physics faculty at LSU.

Since 2025, Gaarde has served as co-Chair of the Committee on Atomic Molecular, and Optical Sciences (CAMOS), a standing committee under the National Academies of Science, Engineering, and Medicine. Garde also served as a member of the AMO2020 decadal study. From 2022 to 2023, Gaarde served as the Chair of the American Physical Society Division of Atomic, Molecular, and Optical Physics (DAMOP) where she oversaw the planning of the 2023 DAMOP meeting. Prior to this, Gaarde had served in several other positions within APS, including sitting on DAMOP committees and serving on the National Organizing Committee for the Conferences for Undergraduate Women in Physics (CUWiP). In 2024, Gaarde was named an LSU Distinguished Research Master for her scholarship in physics.
