\r\n\r\n\r\n\r\nPhotonics Day is a yearly event that aims to promote research discussions and networking among members of the EPFL photonics community, as well as researchers and industry players in the photonics sector. The program includes invited talks from world leaders in the field, a thesis presentation by the winner of the Best EDPO distinction, a scientific picture contest organised by EPC, as well as presentations by students in the Doctoral Program in Photonics, who will compete in the 180-Second Thesis Competition.
\r\n
\r\nThis year the Photonics Day will take place on Thursday October 22, 2026 at the EPFL Forum Rolex.
\r\n
\r\nParticipation is free and includes lunch. Registration opens in September and is mandatory by October 12, 2026. You’ll find both the registration form and the full program on the same page.
Chirality is omnipresent in nature through a fundamental coupling between chirality and angular momentum. Despite extensive experimental evidence, the underlying mechanisms of this coupling remain debated. Here, we will explore how chiral magnetic textures can be stabilized in altermagnets, a new class of magnetism. Turning to structurally chiral magnetic molecules, we will show that chirality is directly linked to their intrinsic magnetic moments. Bringing both together, we will discuss how molecular design can control spin phenomena at hybrid chiral molecule-magnet interfaces. Our findings pave a pathway towards functional \"chiraltronic\" devices – turning a fundamental puzzle into a technological opportunity.

\r\nSmall-angle X-ray scattering (SAXS) imaging probes local nanostructure by raster-scanning a focused synchrotron beam across a sample. This can be extended to resolve nanostructure orientation voxel-by-voxel in three dimensions in a method called SAXS tensor tomography, which we implement in our open-source software package Mumott. In this presentation, I will show how this approach, and its continued development, can be applied across different material systems.
\r\nFor injection-molded polymer packaging, SAXS imaging has resolved the layered anisotropic nanostructure important for its mechanical properties, and, combined with industrial processing simulations, the structure formation during thermal processing. Another example is bone, where resolving structure requires both three-dimensional information and sufficient sampling to capture biological variability. Combining 2D and 3D SAXS imaging, we studied regional differences in the human femoral neck, an anatomical site relevant to hip fractures, and, at higher resolution, resolved alternating chirality between neighboring lamellae within individual osteons, a structural feature proposed on mechanical grounds over a century ago.
\r\nThese examples illustrate how tensor tomography, extended beyond X-ray scattering to wide-angle diffraction and visible-light polarimetry, provides a route to resolving hierarchical structure across a wide range of material systems.

\r\nBio: Marianne Liebi studied food science at ETH Zurich, where she also completed her PhD in 2013, followed by postdoctoral research at the Paul Scherrer Institute and MAX IV Laboratory, Lund. In 2017, she started her own research group at Chalmers University of Technology, Gothenburg, and was appointed in 2021 as tenure-track Assistant Professor at EPFL, where she heads the Laboratory for X-ray Characterization of Materials (cam-X) within the Institute of Materials, in a joint position with the Paul Scherrer Institute (PSI). Her research develops advanced X-ray and optical imaging techniques, centered on small-angle X-ray scattering (SAXS) in 2D and 3D, to resolve the hierarchical structure of materials ranging from fiber composites to pharmaceutical formulations and bone.
The final works of the Master’s students unfold as the outcome of individual journeys of research, exploration, and design. Each project traces its own path, yet together they open a shared field of questions about architecture today, spanning territory and public space, housing, industrial and cultural heritage, and architecture in the mountains. As the Final Juries take place, each project enters into dialogue with invited critics and faculty, revealing not only proposals, but also the questions, intentions, and explorations that shaped them.

The Mary Ann Mansigh Conversation series focuses of non-strictly technical topics of cultural interest for the simulation and modelling community. The format reflects the informative and informal nature of these sessions, with talks introducing the subject followed by a conversation between the speakers and the audience.
\r\nThe lecture series \"Mary Ann Mansigh Conversation series\" is co-organized by CECAM (https://www.cecam.org) and MARVEL (http://nccr-marvel.ch/) at EPFL.

\r\n
\r\nArtificial intelligence is changing how algorithms are conceived, how software is written, and how its outputs are verified. This conversation takes stock of where the field of simulation and modelling stands today and opens a discussion on future directions and best practices — how to safeguard reliability and scientific creativity, how to adapt notions of authorship and ownership for AI-assisted code, and how to preserve and ideally enhance the rich commercial and academic software ecosystem that has driven the growth of computational science in research and development.
\r\n
\r\nWe invite submissions for contributed talks. If you would like to propose a contribution, please submit your abstract using this form. Deadline October 13, 2026.
\r\n
\r\nThe conversation will take place at EPFL, in room BCH 2103 and online.
