Kirsten Kraiberg Knudsen is a professor of astrophysics in the department of Space, Earth and Environment at Chalmers University of Technology.

[1] Her research concerns galaxy formation and evolution.

She is a member of the Swedish Young Academy [2] and the International Astronomical Union (IAU) [3] Knudsen studied at the University of Copenhagen, and at the University of Leiden where she received a PhD.

Knudsen's research focuses particularly on star forming galaxies at cosmological distances.

She uses large, modern telescopes such as ALMA, VLT, IRAM PdBI, and VLA to study the properties of redshift z=2–7 (lensed) submillimeter galaxies and quasar host galaxies.
