Marianne Liebi

Marianne Liebi serves as a Tenure Track Assistant Professor at the Swiss Federal Institute of Technology Lausanne (EPFL), affiliated with the School of Engineering (STI), Institute of Materials (IMX), and specifically the Laboratory for X-ray Materials Characterization (CAM-X). She also holds a teaching position within the SMX-ENS division. Her research focuses on advanced X-ray characterization techniques applied to materials science and biological systems.

Her primary research interests include X-ray tensor tomography, small-angle X-ray scattering, crystallography, and the structural analysis of biological materials such as bones, tendons, and biomaterials. She investigates hierarchical structures across multiple length scales—from nanoscale to macroscopic—with applications in biomedicine, sustainable polymers, and energy storage materials. Her work often integrates computational methods with experimental synchrotron-based techniques.

Analysis of her recent publications reveals a strong emphasis on developing and applying advanced X-ray imaging methodologies to solve complex problems in materials science and biology. Key themes include structural characterization of biological tissues (e.g., narwhal tusks, bone healing, breast cancer metastasis), analysis of polymer nanocomposites, and in-situ studies of material behavior under mechanical or chemical stress. Her research bridges physics, engineering, and life sciences through innovative multi-modal imaging approaches.

Liebi actively supervises six doctoral students and teaches courses including Structure of Materials (covering crystallography, amorphous materials, and characterization techniques) and Material Science at Large Scale Facilities (focusing on X-ray and neutron research methods). Her laboratory (CAM-X) is located at MX F 310, Station 12, 1015 Lausanne, and she utilizes major research facilities including synchrotron beamlines for her experimental work.
