Short Bio

Research in Computer Graphics
Stefanie Hahmann is a professor at the University Grenoble INP, France, and a member of the INRIA research team Anima, part of Laboratoire Jean Kuntzmann. A graduate in Mathematics from the TU Braunschweig and University Paris VI, she received a Ph.D. in Computer Science from the University of Kaiserslautern in 1994. She was an associate professor from 1995 to 2005 and became a full professor in 2006.
Her research focuses on computer graphics and geometric modeling. She is interested in the development of geometric models and computational tools for the expressive representation, synthesis, modeling and computational fabrication of shapes. Grounded in the differential geometric properties of free-form surfaces, her work mainly centers on the creation of user-friendly algorithms that make the design and manipulation of 3D virtual objects more accessible to users. Contributions over the years include high-level models for 3D shapes and animation, reconstruction of shapes from sketches and sensor data, multiresolution methods, feature detection, shape deformation tools, applications to CAD/CAM, my early surface fairing and interrogation algorithms.
Stefanie Hahmann was program co-chair and general co-chair of many international conferences in the field of shape modeling and has organized five Dagstuhl seminars on Geometric Modeling. She served in the steering committees of SMI, SPM, SIAM GD and is now a member of the editorial boards of Computer Aided Design (CAD) and Computers & Graphics. In France, she led the French Geometric Modeling working group (GTMG) part of CNRS for more than a decade. Stefanie Hahmann is a Fellow of the Solid Modeling association and in 2022, the Alexander von Humboldt Foundation awarded her the Gay-Lussac Humboldt Prize.
