M Bussonnier is a Senior Software Engineer with 15 years of experience and a PhD in (Bio)Physics who has been a founder, core developer and steering council member of IPython/Jupyter since 2012. Based in Villeurbanne, France and currently at Quansight, he blends deep scientific computing expertise with full‑stack engineering—shipping backend kernel and server improvements as well as front‑end UX and notebook extensions across flagship projects like JupyterLab, nbconvert, ipywidgets and the Python core. A heavy Pythonista, he pairs rigorous research training with practical DevOps and packaging experience (PyPI, pip, flit) and a track record of improving documentation and developer ergonomics across NumPy, SciPy, pandas and Dask. Notably, his contributions reach widely used ecosystems—editing core error handling in CPython and improving interactive tooling such as prompt-toolkit, CodeMirror and matplotlib—so he often operates at the intersection of developer experience and scientific reproducibility.
