The Plasma Diagnostics and Modelling research group welcomes its newest team member, Dr. Ronny Jean-Marie-Désirée, who will expand our capabilities in ultrafast optical diagnostics. As part of his role, he will work with the streak camera system, supporting time‑resolved studies crucial for advancing plasma and material research.
We are delighted to introduce Dr. Ronny Jean-Marie-Désirée as the newest member of the Plasma Diagnostics and Modelling (PDM) research group at the Department of Plasma Physics and Technology and CEPLANT. His expertise will strengthen our experimental capabilities in fast optical diagnostics and time‑resolved plasma analysis.
Why Brno?
"During my PhD, I came across a lot of research, including the work of Tomáš Hoder and his colleagues. Their studies on cross-correlation spectroscopy really caught my attention because they were exploring ideas close to mine – how to characterize plasma at different scales: spatial, temporal, spectral, depending on what you want to understand.
What fascinates me most now are the very first moments of a discharge and how initial conditions shape everything that follows. That’s why I reached out directly to Tomáš and his team, who are fully focused on plasma diagnostics. It just felt like the right environment to keep pushing in that direction."
Dr. Ronny Jean-Marie-Désirée received his master’s degree in material sciences at Université de Toulouse. He continued with his PhD studies at Université de Lorraine in Nancy, France. His research focuses on implementation and characterization of ns-time scale low- and high-pressure discharges to understand the plasma dynamics in both cases. This knowledge aims to optimize plasma applications by using them at their effective state.
Why Physics?
"For as long as I can remember, I’ve always been a curious person. Science has always been a way for me to understand the world around me and feed that curiosity. That’s really what guided me through my studies, as I discovered with fascination fields like thermodynamics, electromagnetism, and even chemistry.
So why a Master’s in Materials Science? Honestly, because it felt like the field that brought together the widest range of physics topics. And it was actually during that master’s program that I first heard about plasma-assisted deposition processes.
There’s also something simply beautiful about plasma. Not just scientifically, but visually too. That mix of curiosity and aesthetic appeal is what pushed me toward studying this phenomenon more deeply. Ideally, I’d love to zoom all the way down to the scale of an electron and watch how it interacts with its environment."
Research Focus at CEPLANT
At Department of Plasma Physics and Technology and CEPLANT he will focus primarily on research involving our new streak camera system. The streak camera is our latest addition and a key instrument for capturing ultrafast optical phenomena with high temporal resolution. His role will include developing measurement procedures, support ongoing experiments, and contribute to projects that rely on precise time‑resolved characterization of plasma processes and material interactions.
Looking Ahead
We are excited to have Ronny on board and look forward to the expertise and fresh perspective he brings to the team. His contribution will help advance both our diagnostic methods and the broader research activities within the PDM group.

Michal Pazderka completed a two‑week research stay at Université Paul Sabatier Toulouse III, where he collaborated with the group of Prof. Nicolas Naudé on advancing new diagnostic methods in plasma physics. The stay was supported by the COLOSSE project, which enables the expansion of international cooperation and the transfer of expertise to our department.
Starting January 1, 2026, the Department of Plasma Physics and Technology and CEPLANT are opening a new chapter in research. With several new projects in both fundamental plasma science and applied materials technology, the coming years promises exciting advances in diagnostics, coatings, and next-generation applications.
