Super-resolution microscopy for dynamic structural cell biology
Prof. Dr. Jonas Ries
University of Vienna, Vienna, Austria
Optical superresolution microscopy ideally complements electron microscopy for studying protein structure and dynamics in cells. The high contrast of the fluorescence label allows investigating individual structures in various conformational states without averaging, and live cell superresolution microscopy can directly probe dynamics. I will showcase the power of super-resolution microscopy by discussing two projects from the lab. First, I will show how single-molecule localization microscopy allowed us to understand the structural organization and dynamics of the complex machinery that drives endocytosis, an essential cellular process for the uptake of molecules. Second, I will show how we use MINFLUX to measure conformational changes of proteins in the living cell.
The lecture will be held in English.
Jonas Ries is a full professor of advanced microscopy and cellular dynamics at the Max Perutz Labs and head of the Department of Structural and Computational Biology at the University of Vienna. He is the recipient of the prestigious ERC Consolidator Grant, the Fluorescence Young Investigator Award, and the Frontiers of Science Award. He has led several international projects, including HFSP, CZI, and Horizon Europe.

Controlling light with light
Prof. Dr. Igor Muševič
Jožef Stefan Institute, Ljubljana, Slovenia
Our planet is crisscrossed with optical fibres that carry enormous amounts of information every second at the speed of light. These data travel as extremely short laser pulses to data centres, where they are converted into electrical signals, stored, processed, and then transformed back into light signals that continue their journey through the optical network to internet users. Because the ever growing volume of data flowing across the web is driving a rapid increase in electricity consumption in data centres – primarily for converting light into electricity and back again – scientists are searching for ways to replace electricity with light inside data centres and computers. In other words: how can we redirect light using light itself, and how can we compute using light? Over the past decade, this challenge has given rise to the rapidly advancing field of silicon photonics, which integrates seamlessly with modern microelectronics. In the lecture, I will present the paths and pitfalls of a more unconventional approach, in which we harness the self organising properties of soft matter and liquid crystals to steer light with light.
The lecture will be held in Slovenian.

Grand opening of the new Tandetron accelerator
Tandetron is the only research accelerator in Slovenia. Since 1997 it has provided a stable research environment for domestic and foreign researchers, leading to top-tier results and publications. The accelerator is also part of numerous international consortia. After an extremely successful 28 years of operation, the accelerator is now entering a new era.
The central component of the Tandetron tandem ion accelerator is the heart of the infrastructure research Microanalytical Centre within the Infrastructure Programme of the “Jožef Stefan” Institute. Preparations for the upgrade were thorough and have been underway for the past few months, and during the Jožef Stefan Days, researchers will have the opportunity to use the ion beam in the upgraded accelerator for the first time.
The ions will now be electrostatically accelerated by a rectifier with a voltage of up to three million volts, which means a 50 percent increase in voltage compared to the existing system; The acquisition opens up entirely new areas of research.
Therefore, we will honour the start of operation of the improved Tandetron accelerator with a ceremonial opening and a short presentation.

Why is the shadow black? Do animals ever get bored? And how did the universe come to be? In finding answers, the Radiovedni team will be joined by a host of professionals – a sharp team of young physicists, chemists, biologists, and zoologists.
From JSI, we will be joined by:
– Gregor Medoš (physics)
– Nikiša Plešec (physics)
– Jošt Tručl (chemistry)
– Gašper Žun (biology)
– Gregor Belušič (zoology)
Join us on Tuesday, 24 March 2026, at 6.00 pm in the Great Lecture Hall of the Jožef Stefan Institute! The Radiovedni circle of questions, thoughts, guesses, and answers, will be orchestrated by Nik Škrlec, Ajda Kus, Neža Borkovič and Maja Ratej.

Metals under the pressure of sustainable development
Prof. Dr. Ingrid Milošev
Jožef Stefan Institute, Ljubljana, Slovenia and Valdoltra Orthopaedic Hospital, Ankaran, Slovenia
Due to the growth of the global population and the rapid development of modern and green technologies, the consumption of metals is continuously increasing. The life cycle of metals begins with the extraction of natural resources, continues with processing and the manufacture of metal products, and concludes with their recycling or disposal. Corrosion plays a key role in this cycle, as most metals gradually deteriorate when exposed to the environment. Corrosion products form on the surface, differing from the base metal in their chemical, physical, and mechanical properties. As a result, the functional performance of metal products or structures declines, along with their energy efficiency, productivity, and ultimately their safety. Metal corrosion also represents a major economic challenge. Therefore, the efficient use of natural resources and the extension of the service life of metallic materials are essential conditions for a more sustainable future. In the lecture, I will present the main methods of corrosion protection, which play a central role in extending product lifetime and reducing the environmental impact of industry.
The lecture will be held in Slovenian.
Ingrid Milošev is a scientific councilor at the Jožef Stefan Institute and a full professor at the Jožef Stefan International Postgraduate School. In the past, she served as a member of the Scientific Council of the Jožef Stefan Institute and as head of the Department of Physical and Organic Chemistry. In 2025 she received the prestigious European Corrosion Medal from the European Federation of Corrosion.

How AI learns to see, generate, and judge fairly
Prof. Dr. Nicu Sebe
University of Trento, Trento, Italy
In the first part of the lecture, I will explore how we teach AI to generate videos without relying on detailed annotations or object‑specific labels. By training on collections of similar videos – such as faces or human bodies – the model learns to generalize across an entire category. Building on this idea, we developed a Learnable Game Engine (LGE) that learns from simple monocular videos to keep track of scenes and objects and to re‑render them from different viewpoints. Much like a real game engine, it captures basic physics and logic, allowing users to control the scene or guide virtual agents through high‑level language instructions. The second part of the lecture turns to the safety and fairness of generative AI. Most existing approaches look only for predefined types of bias, but real‑world systems can exhibit unexpected ones. To address this, we introduce OpenBias, a method that uncovers and measures previously unknown biases in text‑to‑image models without relying on any preset list. Our experiments show that OpenBias aligns well with established methods and with human judgment, offering a more flexible way to assess fairness in generative systems.
The lecture will be held in English.
Nicu Sebe is a full professor at the University of Trento, where he leads research in multimedia information retrieval and human-computer interaction in computer vision applications. He is a co-editor in chief of the Computer Vision and Image Understanding journal and has held numerous leading organizational roles at major conferences, including ACM Multimedia, ICCV, ECCV, and CVPR.

How communication supports us in our professional and private lives
Miha Bavec
Director of Transformacija Ltd.
We are social beings. We cannot live without others, whether it is our upbringing, work, or socializing. It doesn’t matter if we are sociable or not. Sociability merely reflects an individual’s need to socialize with others. However, even non-social individuals who act independently, are self-motivated and self-affirming, are at the limits of their existence and actions, dependent on other people, such as colleagues, managers, financiers, clients, buyers, and so on. Thus, there is always an opportunity for growth in acquiring new communication skills and ways of thinking that support us in understanding relationships. Even for those already skilled.
The lecture will be held in Slovenian.
Miha Bavec is a top business trainer and coach, specializing in development of leaders and organizations, and the founder, owner and director of the company Transformacija. His passion is supporting individuals and companies in adopting better ways and methods needed for growth, development and progress. More than 200 successful Slovenian companies have trusted him to build more efficient processes, develop leadership competencies, key personnel and strategic leadership teams. Through a relaxed and practical way of working, he equips individuals with knowledge that they can implement in their everyday lives. In his 20-year career, he has conducted more than 14,000 training sessions and more than 5,000 hours of coaching, and educated more than 60 coaches and 20 trainers.

The research carried out by the Department belongs to the broader field of nuclear technology and safety. Interdisciplinary research connects thermohydraulic, strength and safety analyzes and experimental results of THELMA’s own laboratory.
The multidisciplinary research of the Department of Environmental Sciences focuses on the combination of physical, chemical and biological processes that influence the environment, man and human activities. Therefore, the work is based on three main areas: development, optimisation and validation of analytical methods, study of geochemical processes that influence cycling and transformations of substances and elements, and environmental impact assessment which evaluates the risk that human activities present for human health and for the environment.
