Facility for Advanced Imaging and Microscopy
High-end light and electron microscopes, and cutting-edge imaging software and analysis tools
The Facility for Advanced Imaging and Microscopy (FAIM) supports FMI scientists and collaborators with cutting-edge light and electron microscopy, high-content screening, and image analysis.
Our goal is to provide expertise, high-end instrumentation, and technical support to researchers in the institute, so they can focus on their biological questions. We therefore:
- Provide access to state-of-the-art acquisition systems and analysis workstations.
- Maintain instruments and workstations to ensure quality and efficiency.
- Advise and train scientists to ensure optimal usage of our hardware and software.
- Develop workflows for data acquisition, analysis and storage.
- Interact with other institutes to benefit from the know-how among the Swiss, European and worldwide networks of microscopy and imaging.
Light microscopy (LM)
Light microscopes are available for a variety of purposes, e.g.: analyze and quantify molecular and cellular dynamics, (co-)localize labels, measure molecular interactions and concentrations. Our microscopes can accommodate a diversity of samples, especially living specimens. We offer a very large palette of imaging modalities, from wide-field imaging to single-point and spinning-disk confocal, structured illumination, TIRF, slide scanning and 2-photon/NLO imaging. Expertise is available on any aspect of the entire process of experiment design, sample preparation and image acquisition.
Electron microscopy (EM)
We provide EM support for biological samples using transmission electron microscopy (TEM) for 2D ultrastructure or immunolabelling, and serial block-face scanning electron microscopy (SEM) for 3D tissue volumes. We are offering service and training to FMI researchers ranging from sample preparation to image analysis. Since 2016, we are sharing an EM facility with Novartis on the St Johann Campus that provides cutting-edge EM to researchers from academia and industry.
High content screening (HCS)
We offer complete support for HCS projects: from assay development and upscaling to image and data analysis. As HCS involves a new mindset to plan experiments, we are involved in the projects from the conception down to the data analysis and statistics. We offer access to instruments enabling the automation of both sample preparation and imaging, providing user training and service. As part of the HCS project lifecycle, we offer tools for visualizing, processing and exploring large imaging datasetsOur special area of expertise is automated culture and imaging of complicated 3D model systems.
Image & data analysis
Acquisition at the microscope is just the first step to address biological questions. The acquired data must then be visualized and carefully analyzed to prove or reject the working hypotheses. Various software tools exist for visualization and generic quantification, but dedicated customized solutions are frequently needed for more complex analyses. We provide continuous training on tools and theory, offer advice and support for image analysis questions, and we develop customized solutions for advanced image analysis workflows, either as stand-alone software tools or plug-ins for the existing software packages, that specifically address our users' questions.

After gaining an Engineering degree in Biochemistry and a MSc in Immunology in Paris, Laurent did his PhD in Molecular Biology at the Institut Pasteur in Lille and the IGBMC in Strasbourg, where he also did postdoctoral research on in vitro transcription assays. He then moved to the University of Lausanne, where he used advanced microscopy techniques to study gene regulation in living cells.
