We are pleased to announce a new edition of FBI Connect, our webinar series dedicated to imaging-related developments and innovative approaches within the France-BioImaging community.

This session will focus on a new generation of fluorescent probes, with Ludovic Jullien, researcher at the ENS-PSL Chemistry Department.

The webinar will take place on Thursday, November 5, 2026, from 11:00 to 12:00.

Interested in joining us? Register now and save your place!

Controlling fluorescence with light

Ludovic Jullien will present his recent work on light-responsive fluorescent tags based on the FAST system.

FAST is a non-covalent fluorogenic labeling system in which a fluorogen becomes fluorescent when bound to a protein tag. By exploiting the photochemical properties of these fluorogens, Ludovic Jullien and his collaborators showed that FAST tags can acquire new light-responsive behaviors, including reversible photoswitching and, when two fluorogens are combined, photoconversion.

These dynamic properties open new possibilities for super-resolution microscopy, dynamic contrast imaging and multiplexed imaging, by providing additional information beyond fluorescence color alone.

Want to learn more about these new light-responsive tools for bioimaging? Join us on November 5 and register now!

Four new invited speakers have been announced for SFBS 2026, further enriching the scientific programme dedicated to super-resolution microscopy for biological imaging.

We are happy to announce that the new edition of our machine learning competition, Light My Cells 2, is now open! This Challenge completes the previous Light My Cells in 2024 with additional data and a new prediction task.

Light My Cells 2 is organized in two phases, the validation phase (September 21st – November 30th) and the evaluation phase (December 1st – December 13th).

Find more information below.

The Challenge: a data machine learning competition

Since 2024, France-BioImaging organizes its data machine learning competition in the aim to respond to the microscopy community issues.

With Light My Cells 1, participants predicted fluorescence images of four cellular structures – nucleus, mitochondria, tubulin, and actin – from label-free transmitted-light microscopy images acquired using bright-field (BF), phase-contrast (PC), or differential interference contrast (DIC) modalities. This technique is also known as in-silico labelling.

This Challenge established a large-scale, multi-site benchmark for evaluating in-silico fluorescence prediction from transmitted-light unlabeled microscopy images under realistic imaging variability.

Light My Cells 2 introduces additional training data and a new prediction task to reconstruct the fluorescence maximum-intensity projection (MIP) from transmitted-light image stacks.

Light My Cells 2 tasks

To help the participants build their algorithm, they have access to a training dataset of 76 studies, which represents more than 150 000 images. From these acquisition-sets, participants will have to create an algorithm to:

  • Predict the best-focused output-images of four fluorescently labelled organelles from label-free 2D transmitted light input-images.
  • Predict the MIP output-images of four fluorescently labelled organelles from a stack of 2D input-images of label-free transmitted light.

Key informations

The Challenge is now open and you can register to access the training dataset and start building your algorithm!

From September 21st, 2026, the validation phase begins – you will be able to test your algorithm and the submission process, up to five test submissions.

From December 1st to 13th, 2026, the evaluation phase will start – participants will have one final submission.

The results will be announced on December 18th, 2026.

The National Coordination Team and the Executive Board are proud to announce the winners of the FBI Image Contest 2025:

1st Place: Nicolas Barois, BioImaging Center Lille (BICeL)

Gut Flower-Flora

Cross-sectional view of a thin slice of mouse gut. By cutting a thin slice of the gut, the inner went out. Normally I cut the gut in small tubes, which are cut in two longitudinal pieces. I kept this piece because I was curious to see it with the SEM.
Scanning Electron Microscopy

2nd Place: Vishwadeep Mane, Plant Reproduction and Development Laboratory (RPD, ENS Lyon)

The Puzzled Awakening

Cotyledons, the first leaves of a plant, break free from the seed to launch life after germination. Emerging as a pair, they unfold into a nearly perfect, circular lamina that captures light for photosynthesis. At the microscopic scale, their surface reveals a mosaic of interlocking puzzle-shaped cells, dotted with stomata. These intricate cell shapes are nature’s solution to balancing internal pressure, relieving mechanical stress, while guiding growth into a robust and harmonious form. Between the cotyledons rises the first genuine leaf, a quiet promise of the plant’s future. Cotyledons mark the awakening of life, and in their puzzled cells, we see both resilience and beauty.
Confocal Laser Scanning Microscopy

3rd Place: Simli Dey, Membranes and Cellular Functions Team, Institut Curie

Kaleidoscope

Directing branched actin filament growth from a curved lipid membrane site.

On the occasion of the launch of France-BioImaging’s new challenge, Fuse My Cells, we reached out to the winners of the previous edition (Challenge – Light My Cells). Today, we invite you to meet Yu Zhou, research associate at the Leibniz Institute for Analytical Sciences (ISAS).

Hello Yu, I’m glad to meet you! Where are you from?

I am originally from Jiangsu Province, China. Currently, I live in Dortmund, Germany, where I work at the Leibniz Institute for Analytical Sciences (ISAS).

What is your background and your professional activity?

My professional background is in biomedical image processing, where I focus on applying AI algorithms to analyze and enhance imaging data. A key aspect of my work is improving efficiency, such as using model quantization and pruning to reduce inference energy consumption, as well as applying biomedical image compression to lower storage and bandwidth costs. Recently, I have also been exploring research in foundational models for omics data, aiming to bridge different modalities in biomedical research.

Why did you decide to participate in the France-BioImaging challenge “Light My Cells”?

I learned about the Challenge “Light My Cells” through my supervisor, who discovered the competition on X and shared it with me. I had never participated in a competition on the Grand Challenge platform before, so I wanted to experience the full process of such a challenge. Also we found the problem itself very interesting, and thanks to a previous project, we were already somewhat familiar with this topic.

What was the most challenging part of the competition for you?

The most challenging part of the competition was data processing. We used a semi-automated approach that combined an automated pipeline with manual curation for data filtering. This process was quite time-consuming.

How did you manage your time during the competition?

For the experimental phase, our team worked in parallel on several tasks: data cleaning, trying different network architectures, and conducting hyperparameter searches. However, when it came to writing the final paper, we were somewhat rushed as we had only about two weeks left to complete it.

What are your thoughts about Challenge 2 “Fuse My Cells”?

What excites me most about this challenge is its innovation. Predicting a fused 3D image directly from a single view bypasses some potential issues of multi-view fusion, such as light toxicity. Additionally, with a well-constructed dataset, the solution could be more generalizable, enabling models to perform image restoration across all the various 3D perspectives.

Do you have any advice for the participants of Challenge 2?

  1. Pay attention to the data.
  2. Keep an open mind and be willing to explore different strategies, including model selection and training methods.
  3. Manage your time wisely by balancing the experimental phase and paper writing.

Thank you very much for your time, Yu! I’m sure your testimony will be useful for the participants of Challenge 2.

On the occasion of the launch of France-BioImaging’s new challenge, Fuse My Cells, we reached out to the winners of the previous edition (Challenge – Light My Cells). Today, we invite you to meet Marek Wodziński, a post-doc in the Institute of Informatics at HES-SO Valais-Wallis in Switzerland.

Hello Marek, I’m glad to meet you! Where are you from?

I am from Poland – currently working both in Poland (AGH University of Kraków) and Switzerland (HES-SO Valais).

What is your background and your professional activity?

I have a PhD in Biomedical Engineering & Computer Science from AGH University of Kraków and I am currently working as PostDoc in HES-SO Valais. I have worked in the field of medical image analysis, computer vision, machine & deep learning for more than 7 years so far.

Why did you decide to participate in the France-BioImaging challenge “Light My Cells”?

Taking part in scientific challenges is a great way to explore previously unknown subfields and gain valuable experience in new topics. When I came across the challenge on the IEEE ISBI website, I immediately recognized it as an opportunity to deepen my expertise in biological imaging and expand my research network.

What was the most challenging part of the competition for you?

As in every challenge – to fully understand the goal, the data, and the associated challenges. The most time-consuming part in scientific challenges work is to explore the dataset and understand which challenges related to the data are the most important, e.g. in the Light My Cells challenge it was connected with significant dataset imbalance, both at the study and organelles level.

How did you manage your time during the competition?

I started with exploring the data and thinking how the problem should be addressed. The process took me more than half of the time I spent on the challenge. Then, I implemented and debugged the training and evaluation scripts. Finally, I queued all ablation studies on our supercomputing platform (ACK Cyfronet Athena) and chose the best model.

Do you have any projects or aspirations related to imaging or research after this competition?

The competition improved my experience related to image-to-image translation tasks that could be further used in different downstream applications I am working on, e.g. MR-to-CT translation in radiology. I continue to work both in digital pathology and radiology where I develop novel deep learning techniques.

What are your thoughts about Challenge 2 “Fuse My Cells”?

Definitely the most difficult aspect of the Fuse My Cells challenge is the timeline – there is only 1.5 months to develop and evaluate the solution.

Do you have any advice for the participants of Challenge 2?

I suggest starting with exploring the data and understanding the associated challenges. Then, it is wise to explore the current state-of-the-art to understand the best-performing solutions and improve them. The practical part related to developing the scripts and  performing ablation studies is usually significantly less influential.

Thank you very much for your time, Marek! I’m sure your testimony will be useful for the participants of Challenge 2.
