Les techniques d’imagerie photoniques ont longtemps été limitées à l’étude d’échantillons biologiques sortis du contexte physiologique et métabolique de l’animal comme les lames de cellules ou les boîtes de culture. Désormais, il est technologiquement possible de visualiser les interactions biologiques au sein même de l’animal vivant par la microscopie in vivo (animal entier) ou in situ (coupe épaisse de tissus vivant). Des verrous technologiques existent qui peuvent être levés avec l’avènement des technologies d’impression 3D et autres outils open source à bas coûts, permettant de faciliter grandement la mise en place de la microscopie intravitale dans les laboratoires de recherche.

Objectifs de la formation : mettre en place différents moments d’échanges entre les chercheurs, les ingénieurs formateurs et les stagiaires autours des thématiques scientifiques et techniques sous-tendues par la microscopie intravitale.

Cutting-edge techniques using a wide range of image-formation mechanisms — including magnetic resonance imaging, positron emission tomography, infrared and optical microscopy, electron microscopy and X-ray imaging — will be discussed, with a focus on multimodal and multiscale imaging methods, together with supporting technologies such as computer-aided image analysis and modelling.

What is the structure? The summer school will provide different tracks for participants with a background in life sciences and physical sciences, respectively. The students will have lectures in the morning and hands-on sessions in the afternoon. The highlight is a full-day project in a topic of choice within an academic institution or institute. The program is rounded off with the EXCITE Symposium on “Bringing algorithms close to
data and scanner: distributed learning for biomedical imaging" and an industry day.

How do I attend? Admission is decided based on the applicant’s curriculum vitae, a statement of purpose and applicant’s references. Students who have not yet started a PhD program may apply for a stipend. Interested students are kindly asked to submit their application pack including their study grades and reference letter on our homepage (https://excite.ethz.ch/education/summer-school/Application2022/Application2022.html)

APiL is an advanced management course in Life Sciences and Health, developed by the Institut Pasteur (IP) and the Ecole Supérieure de Commerce de Paris (ESCP). APiL aims to provide the keys to develop Biotech, Medtech, AI for Health, or even a connected medicine application. It is an intensive and demanding training involving teachers from two institutions, each renowned in their field.

It is a part-time course for professionals, doctoral students, and Postdocs in Life Sciences and Health who want to learn from startup creation to its business & management.

The academic year starts in September. Students follow business courses, capsules modules on entrepreneurship and start-up creation in healthcare, workshops, companies visits, capsules, and other seminars.

Students will obtain a diploma from both Institutions and will become ESCP & Institut Pasteur Alumni.

At the end of the program, students have a global vision allowing them to become successful entrepreneurs, innovation leaders, or top managers in life sciences and health through an intensive, specialized, carefully-crafted, advanced program co-created and designed by Institut Pasteur & ESCP Business School.

Besides complex networks of protein interactions, the life of the cell is also governed by biophysical parameters. The objective of this course is to disseminate practical knowledge concerning recent quantitative fluorescence microscopy methods aiming at characterizing biophysical properties of the living samples. In the present practical course, we wish to introduce recent imaging methods allowing participants to assess three essential biophysical components of the intracellular environment:

- the diffusion-reaction dynamics
- the physico-chemical state
- the mechanical tensions

Each component will be assessed in living cells and tissues using complementary methods. Hands-on sessions will focus not only on data acquisition but also on the methods available to quantitatively analyze and model these data.

The applicants will be able to register either for on/site or online participation. Online participants will have access to all talks and round tables as well as interactive discussion via chat. Practicals will only be accessible to onsite participants. If along the selection process, some applicants cannot be selected for on/site participation due to the limited number of people that can participate in the practicals, we will offer them the possibility to participate online.

This workshop will present the principle of light-sheet fluorescence microscopy (LSFM). Seminars will
cover basic principles, applications, and challenges of LSFM, while practical sessions will allow to test different
LSFM implementations and to learn sample preparation and data processing methods.
The workshop will be divided in two parts:
A first theoretical part in Bordeaux from the 16th to the 18th of May 2022 which will cover basic principles, applications and challenges of LSFM imaging through seminars,
A second practical part along June 2022 where you will have the possibility to choose the set-up on which you want to be trained amongst many systems available within the France BioImaging community.

Fluorescence microscopy techniques play an essential role in biology and medicine. A very rapidly developing field concerns nanoscale imaging (“nanoscopy”), which today ties together different fields of biology such as structural and cell biology. Similarly, “single molecule” imaging and spectroscopy techniques are in rapid development and play a central role in life science research. All fluorescence microscopy methods are based on labelling samples with appropriate markers: fluorescent proteins, organic fluorophores or nanoparticles. All these type of markers are characterized by very complex photophysical behaviors, leading to blinking, chromatic conversion, photoreactivity, etc… However, nanoscopy and single molecule spectroscopy or imaging, specifically rely on the ability to understand and control these properties.

The school we offer is motivated by the fact that more and more laboratories around the world are committed to implementing advanced microscopy techniques, especially super-resolution, with an increasing number of dedicated platforms. However, there is a lack of overall knowledge about the selection of fluorescent markers, their properties and mechanisms, and the type of artifacts they can create. The school’s objective, through interdisciplinary teaching between physics, chemistry and biology, is to overcome this gap by transferring knowledge to the participants’ laboratories. Our school also aims to make participants aware of new developments in the field in order to prepare them to become major players in the breakthroughs that may result from them.

France BioImaging (FBI) is organizing a remote training on Light-Sheet Fluorescence Microscopy (LSFM), which enable 3D imaging of biological samples with unprecedented spatio-temporal resolutions and low perturbing effects.

LSFM methods actually cover a large variety of implementations which allow imaging a wide range of sample types, from single cell to whole organs or organisms both live and fixed. These new imaging capabilities are revolutionizing the way we visualize our samples and address biological questions. However, imaging with a light-sheet microscope raises many questions about the choice of the set-up depending on the sample to image, the sample preparation and mounting protocols or the data management (storage, visualization, quantification). Thus, it can be difficult to find its way through the numerous microscope implementations, protocols and tools that have been extensively developed over the last 20 years. We therefore decided to review all those questions in a remote training.

Our goal is to help people who want to jump into the world of 3D imaging and are seeking the best solution for their samples and biological questions. In that perspective, we will provide a comprehensive picture including all the possibilities and challenges regarding LSFM.

The training will be divided in 3 parts:

- Theoretical courses on LSFM
- Practical demonstrations of several LSFM implementations available throughout the FBI infrastructure
- Live online question and answer session

For the two first parts, videos will be available on a Youtube FBI channel. The participants will have 3 weeks, from the 15th of February to the 5th of March 2021, to watch those videos and will be invited to ask questions or comment.

FBI experts will then answer all questions during a live interactive video chat on the third week of the training (5th of March where participants will have the opportunity to directly interact with the experts.

Expansion microscopy virtual workshop.

For the convenience of our global attendees, we will be conducting two sessions: Session one (10:00-12:30 UTC), Session two (16:00-18:30 UTC).

This online course will focus on several key areas including data management of image data using OMERO open source data management solution, cloud-based sharing of image data using next-generation image file format, and image data repositories including Image Data Resource (IDR) and EMPIAR (Electron Microscopy Public Image Archive) as well as new developments within BioImage Archive.

Bioimage analysis has become a keystone of biological research: the deluge of data produced by increasingly advanced microscopes calls for experts able to guide life scientists in the methods and software to be used to produce quantitative knowledge from this data. Due to the complexity of the data, without such expert guidance, it is very likely that image analysis algorithms may be applied incorrectly, possibly even producing erroneous results. Moreover, the diversity of imaging modalities, analysis algorithms and software solutions is growing so rapidly that even experts are overwhelmed.
This advanced course concentrates on teaching cutting-edge concepts and tools for quantitative image analysis, and will seek to upgrade the competencies of future bioimage analysis experts on both theoretical algorithm advancements as well as on practical implementation skills.

This one-week school provides a hands-on introduction to image processing and analysis, with an emphasis on biologically relevant examples.
Covered topics will encompass :
- Basics in Image Formation
- ImageJ, from everyday use to advanced applications
- State-of-the-art analysis procedures like e.g. co-localisation
- Machine Learning including Deep Learning
- Stitching and registration
- Data analysis using KNIME

This training session will cover the basics of super resolution in photonic microscopy, principally: STED microscopy (STimulated Emission Depletion) and single molecule localization microscopy. We will also present alternative solutions for super resolution like SRRF (Super resolution Radial Fluctuations), Airy Scan, or Computer based pixel-reassignment like ISM (Image Scanning Microscopy), and solution based on light sheet illumination. The mornings will be dedicated to theoretical lectures and application seminars. The afternoons will allow the participants to see demonstrations of these different techniques in front of home-made or commercial systems. The fourth day will be a full hands-on day, as participants will be invited to bring their own samples and test them on the different systems available, like STED microscope, STORM, lattice light sheet, ISM, SRRF….

Rapid advances in live imaging of targeted cellular morphologies and functions underpin the emerging revolution in our understanding of synapses, circuits, and behaviour. In keeping with its long-established tradition, this Cajal course will assemble at its international faculty leading experts in developing and exploiting cutting-edge imaging techniques that have been propelling such advances. How to combine genetically encoded fluorescence labelling with behavioural designs, micro-circuit monitoring, or single-molecule tracking, how to avoid pitfalls of having false-positive observations and inherent noise, how to best analyse your multi-dimensional data will be, among others, the recurrent subjects of the Course.

The use of fluorescence microscopy (wide field, confocal, multiphoton, and now superresolution) in combination with genetically encoded fluorescence probes comprise a powerful set of scientific tools to study live cells. However, surprising little practical and theoretical training in such methods exists within standard curricula, particular at the early stage of training (Masters or Doctorate level). This course offers to cover basic optics principles necessary to understand the origin of microscope resolution and design. Participants will get hands-on experience implementing simple optical configurations to illustrate these fundamental principles. Subsequently, participants will perform experiments on state-of-the-art imaging equipment provided by microscope vendors.
