Katrin Heitmann
Katrin Heitmann is a German cosmologist who uses large computer simulations to study the universe, focusing on how matter is distributed and how the universe expands. She is the Deputy Division Director of High Energy Physics at Argonne National Laboratory. She is the former spokesperson of the LSST Dark Energy Science Collaboration and a senior associate at the Kavli Institute for Cosmological Physics at the University of Chicago. She is also affiliated with the Northwestern-Argonne Institute of Science and Engineering at Northwestern University.
She earned her PhD in 2000 from the Technical University of Dortmund. Her doctoral work, supervised by Jürgen Baacke, was on non-equilibrium dynamics in quantum field theory.
From 2000 to 2011 she worked at Los Alamos National Laboratory, then moved to Argonne. While at Argonne she led a project to move three of the largest cosmological simulations—together about 2.9 petabytes of data—to the cloud.
In 2023 she was elected a Fellow of the American Physical Society for pioneering new techniques in cosmic simulations for precision cosmology and for strong scientific leadership within LSST DESC.
