To cure, prevent, and manage all diseases by the end of the century, we need a much deeper understanding of biological systems. To gain this knowledge, we need to develop hardware and software tools to visualize life’s processes at the level of tissues, cells, and proteins.

We also need to understand context — such as protein interaction in cells and cell signaling in living organisms. Enabling measurement and quantitative insights, and providing access and training to these tools, will allow researchers to make breakthroughs and build on each other’s discoveries.

CZI Imaging Tools: napari



An interactive, multi-dimensional image viewer for Python designed for browsing, annotating and analyzing large images.

These nuclear proteins (histones) in a living roundworm embryo were imaged using the dual-view inverted selective plane illumination microscopy (diSPIM). Maximum intensity projection images are rendered in different colors for visualization.

CZI Imaging Scientist Sara McArdle of the La Jolla Institute for Immunology looks into a microscope. Protective gowns are required, as this microscope is used in studies of infectious agents, such as Zika and Dengue viruses, in addition to a range of inflammatory disorders.

CZI Imaging Scientists & Imaging Software Fellows

CZI’s Imaging Scientists program aims to advance the field of imaging by increasing collaboration between biologists and technology experts and improving the imaging tools that scientists use. CZI also supports Imaging Software Fellows to develop and maintain three critical tools: scikit-image, FIJI / ImageJ, and CellProfiler.

Global BioImaging

CZI supports Global BioImaging (GBI), an international network of bioimaging facilities and communities. These networks of core imaging centers help researchers better understand and identify the biological mechanisms of health and disease using cutting-edge technology. GBI strengthens community building and training worldwide to address the practical challenges of operating open access tools for imaging technologies in the life sciences.
