Six researchers have been awarded doctoral fellowships to begin their doctoral dissertations: Rachel LAURON from the Faculty of Sciences; Océane WATELET, Vera NOVAK, Camille LAMBIET, Alionka WÉRENNE, and Théodore HARDY (who received his grant from ULB under a joint supervision arrangement with UNamur) from the Faculty of Philosophy and Letters. 

Researchers from Namur also achieved great success in securing research fellow grants. Seven of them received this postdoctoral funding. They are Eleonor CELORA, Nataliya PUCHENKINA, Jérémy ARTRU and Bernardino PITOCCHELLI from the Faculty of Philosophy and Letters; Romain MERTENS from the Faculty of Law; and David TALUKDER and François WOITRIN from the Faculty of Economics, Management, and Communication at SciencesPo (EMCP). 

In addition, two permanent F.R.S.-FNRS researchers at UNamur have been promoted to Senior Researcher: Francesca CECCHET and Yves CAUDANO, both members of the Department of Physics and the NISM Institute. 

The Télévie call for proposals also enabled Marc HENNEQUART to secure funding to begin research aimed at identifying the metabolic determinants of the response to arginine deprivation in pancreatic and colorectal cancers. 

Congratulations to them!

Last May, the International Conference on Electroluminescence and Optoelectronic Devices (ICEL 2026), organized at the University of Namur by Professor Yoann Olivier, with the support of Professor Benoît Champagne, provided an excellent opportunity for intellectual and social exchange among researchers from around the world involved in the research, development, and fabrication of light-emitting materials to discuss their recent advances.  

This 15th edition featured plenary lectures for the 125 participants, including both renowned and emerging researchers. The packed five-day program included five presentations by renowned international keynote speakers, 20 presentations by invited speakers, and some thirty oral presentations selected by the organizing committee, as well as two poster sessions featuring more than 50 presentations.   

Participants also had the opportunity to mingle and engage in discussions during the various activities of the social program, which highlighted the City of Namur, its iconic sites, and its shops: a tour of the Citadel’s underground passages, a historical and/or culinary stroll through the heart of the pedestrian zone, a tour of the Félicien Rops Museum and the Grafé-Lecocq cellars, a dinner for guest speakers at the restaurant “Le Balthazar,” and a conference dinner at the restaurant “Le Panorama.”   

Particular emphasis was placed on the active participation of motivated young researchers. A wide range of topics was explored, offering a comprehensive perspective on contemporary advances in the fields of materials science, fundamental physics, and their applications in cutting-edge devices and technologies. 

“A VERY big thank you - this was a really excellent conference - great science and a wonderful sense of being welcome - just how conferences should be!” – Sir Richard Friend, University of Cambridge, UK

“I would like to congratulate you on such an excellent conference. I really liked its scale (not too big), it being single session, affordable, in a nice place, with lots of chance to talk to other participants over coffee/lunch/poster refreshment.   The scientific level was excellent (which I fully expected with you as organisers) and there was good variety in the programme. The social activities/invited speaker dinner and spectacular conference dinner all added to a wonderful week. It was an amazing week.” – Prof Ifor Samuel, St Andrews University, UK

“It was a real pleasure to be at the ICEL conference. It really felt like family and the atmosphere was so warm that it completely overcame the cold weather and my flu. Excellent organization and perfect timing!”, Prof. Illia Serdiuk, University of Gdansk, Poland

“Thanks again so much for the organizational effort, the conference went so smoothly!” – Prof Barry Rand, Princeton University, USA

Professor Barry Rand has, in fact, taken over the reins, as he will be organizing the 16th edition of the conference at the prestigious Princeton University in the United States in 2028. 

The organizing committee would like to thank its sponsors and partners for their support: Universal Display Corporation, Angstrom Engineering, The Royal Society of Chemistry (RSC), Chemistry Europe, the University of Namur, the Namur Institute of Structured Matter (NISM), the Namur Research College (NARC), the C.G.B. (Comité de Gestion du Bulletin) – C.B.B. (Comité van Beheer van het Bulletin), the Namur City Tourist Office, and the F.R.S.-FNRS thematic doctoral schools CHIM, MAIN, and METAMORPHOSE. 

Heritage sciences are experiencing a resurgence at UNamur. This field of research—which involves applying techniques and expertise from the exact sciences (physics, chemistry, biology) to study ancient heritage objects—is reinventing itself thanks to the PHOENIX project, led by seven researchers from the Faculties of Science (Department of Physics) and Philosophy and Letters (Departments of History and Classical Languages and Literatures). 

“PHOENIX emerged from the collaboration of several researchers from different backgrounds, yet all driven by the same desire to study the materiality of heritage objects. One notable figure is Julien Colaux, whose predecessor had led the first heritage science projects at UNamur’s Laboratory of Analysis by Nuclear Reactions (LARN). It’s a sort of return to our roots,” recalls Nicolas Ruffini-Ronzani, a researcher in the Department of History, president of the PaTHs Institute, and one of the project’s leaders. 

With PHOENIX, researchers aim to “make” two types of objects speak: ancient coins and medieval parchments (see box). More specifically, their research is guided by three objectives:

• To understand the composition of the artifacts being studied. For the parchments, to identify the animal species (sheep, goat, or calf); and for the coins, to characterize the metal alloy.
• Gain a better understanding of the production and processing workflow. For example, determine which parts of the animal were used in the production of a parchment.
• To propose the most precise dating possible. 

It is in this last objective that the main challenge lies. “We won’t be able to date these objects to within a year,” warns Olivier Deparis, a professor in the Department of Physics and a member of the NISM research institute. “The idea is to provide a time frame that is as precise, if not more so, than that already provided by paleography (the study of ancient scripts) or textual analysis. If we can narrow it down to a quarter-century, that will already be a significant step forward.”

To achieve this, the PHOENIX team uses various non-invasive techniques, in particular infrared and Raman spectroscopy, time-of-flight secondary ion mass spectrometry (ToF-SIMS), and ion beam analysis (IBA). These approaches—which utilize UNamur’s state-of-the-art tools such as the ALTAÏS particle accelerator (see Omalius #36)—provide detailed information on the physicochemical composition of materials, such as the animal origin and ink formulations for parchments or the type of metal alloy for coins. “The use of the exact sciences will enrich our studies and thus allow us to better understand how these objects were produced in the past,” explains Nicolas Ruffini-Ronzani. “Contrary to what one might think, collaboration between the humanities and the exact sciences has a long history, dating back to the 19^th century, and even much earlier in the case of coins.”

These tools will make it possible to examine parchments and coins down to the finest detail, at the pixel level. These in-depth analyses therefore generate a colossal volume of raw data to process. This is where artificial intelligence comes into play to speed up the processing and reveal the information “hidden” in the data, identifying major trends invisible to the naked eye. 

Above all, it will provide a boost in meeting the challenge of dating the objects under study. Dated documents, such as charters, will thus be used as references to test the model’s robustness by comparing the results obtained with already known dates. “If the results are convincing, the technique could be applied to undated documents,” says Nicolas Ruffini-Ronzani. This would represent a significant breakthrough in historical research.

“The use of machine learning methods is not a panacea,” Olivier Deparis qualifies, however. “We wanted to explore it as an open-ended question to assess its benefits.”

PHOENIX could thus herald a new era for heritage sciences, where artificial intelligence—much like the phoenix after which the project is named—opens up new ways to analyze and understand materials from the past.

The PHOENIX project is funded by the Concerted Research Action (ARC) program from September 2024 to August 2029. It is a continuation of the interdisciplinary Pergamenum21 project, launched in 2014 by the Moretus Plantin University Library (BUMP) under the leadership of Professor Olivier Deparis and dedicated to the scientific study of parchment with a view to improving conservation practices.

Young people from Rochefort showcased the PHOENIX project at the international First Lego League competition, a robotics contest open to students aged 10 to 16. To align with the annual theme focused on new technologies in the field of archaeology, this team from the Rochefort Youth and Culture Center drew inspiration from IBA technology to develop a research game designed to identify the origin of Ancient Greek coins modeled using a 3D printer. Their project caught the jury’s eye and earned them a spot in the national finals, which took place last March. Beyond the competition, this original game will be presented during Family Day at the Malagne Archaeological Park (Rochefort). 

For the MSCA Doctoral Networks 2025 call, 1,616 proposals were submitted and 141 were selected, representing a success rate of 9.6%. In this highly competitive environment, the selection of three projects involving UNamur sends a strong signal: it confirms the scientific excellence of Namur’s teams and their ability to build high-level international partnerships in support of doctoral training and innovation. Six doctoral dissertations will be eligible for funding.

In many neurological diseases, both inflammation of the nervous system and imbalances in the gut microbiota are observed. GlycoAxis aims to go beyond simple correlations by identifying the molecular “messengers” that link the gut, the immune system, and the brain. The project focuses on complex sugars found on the surface of certain bacteria (glycans), which are suspected of playing a key role in immune activation and neuroinflammation. The goal: to better understand these mechanisms and pave the way for new diagnostic tools, imaging techniques, or biomarkers for brain health.

In the face of climate change, pollution, and habitat fragmentation, some ecosystems weather the shocks… while others collapse. ReDiLeep focuses on a key driver of this resilience: response diversity—that is, the fact that different species (or ecological functions) do not all react in the same way to a disturbance. The project aims to better measure and model this mechanism in order to link research more directly to the needs of conservation, restoration, and public policy regarding biodiversity.

Our digital communications rely on light: optical fibers, sensors, and photonic circuits capable of processing information. But with the explosion of data, the rise of AI, and the advent of ever-faster networks, it is becoming crucial to control light dynamically—much faster than is possible with current components, which are often “static.” SPARK is exploring a new approach: combining spatiotemporal metamaterials (nanoscale structures designed to shape light) with light that is itself “structured” in space and time. The result: reconfigurable photonic technologies for computing, imaging, and ultra-fast communications.
