Gabriele Steidl (born Drauschke, 1963)^[1] is a German mathematician whose research interests include computational harmonic analysis, convex optimization, and image processing. She is a professor of mathematics at the Technical University of Berlin.

Steidl studied mathematics at the University of Rostock, earning a doctorate (Dr. rer. nat.) in 1988 and completing her habilitation in 1991.^[2] Her doctoral dissertation, Grundlagen schneller Algorithmen für verallgemeinerte diskrete Fouriertransformationen, concerned fast algorithms for the discrete Fourier transform and was supervised by Manfred Tasche.^[3]

After consulting for a German insurance association, she became an assistant professor at Technische Universität Darmstadt in 1993. She moved to the University of Mannheim as a professor in 1996, and moved again to the Technical University of Kaiserslautern in 2011 before taking her present position at the Technical University of Berlin in 2020.^[2] From 2020-21, she is program director of the SIAM Activity Group on Imaging Science.^[4]
