Stereologie Workshop

Workshop on Quantitative Microscopy 2024

The Stereology workshop Bern in 2024 is planned.

Date: Mon 12 - Fri 16 August 2024

Registration is open until 17.07.2024.

Stereology provides biomedical researchers with efficient and unbiased tools to obtain real 3D data like volume, surface, length, and number of organs, tissues, cells, and organelles from measurements done on microscopic sections.

If this is important for your research, this workshop is for you!

In collaboration with the Microscopy Imaging Center (MIC), University of Bern

Scope

This workshop provides an introduction to state-of-the-art stereology with emphasis on its practical application in biomedicine. Experimental design, sampling, use of stereological probes, estimation of stereological parameters, and the application of statistical methods appropriate for stereology are covered. The workshop encompasses lectures, classroom exercises with real biomedical images, and laboratory practicals demonstrating the implementation of proper sampling and processing techniques on real biological organs.

This workshop is intended for students and researchers from the field of biology and medicine interested in sampling and measurement of 3D structures. Applications involving any kind of microscopy (e.g. light microscopy, confocal laser scanning microscopy, multi-photon microscopy, electron microscopy) as well as non-invasive scanning techniques like CT and NMR are welcome.

Participants should bring their specific projects and questions. During the workshop, there will be ample opportunity for discussions with the instructors.
