CZI EOSS Grantees

Projects funded by the Chan Zuckerberg Initiative's Essential Open Source Software for Science (EOSS) program. CZI EOSS supports software projects that are essential to biomedical research and the broader scientific community. The program recognizes that much of modern science depends on open source software, and invests in the maintenance, growth, and sustainability of these critical tools. This portfolio spans a wide range of scientific domains: - Bioinformatics & genomics (GATK, samtools, Nextflow, Snakemake, Bioconductor) - Neuroimaging (fMRIPrep, FreeSurfer, MNE-Python, Nilearn) - Microscopy & imaging (napari, ImageJ/Fiji, QuPath, Bio-Formats) - Single-cell analysis (Scanpy, Seurat, scvi-tools, AnnData) - Core scientific computing (NumPy, SciPy, pandas, Matplotlib, scikit-learn) - Statistical modeling (Stan, PyMC, ArviZ) - Data infrastructure (JupyterLab, Dask, conda-forge, Zarr) Together these ~200 projects form the backbone of open source scientific software.
