I am a researcher in statistics and machine learning currently working as a postdoc at the Department of Mathematical Sciences at the University of Copenhagen. I also contribute to open-source software in various languages, including Python, R, Julia, C++, and Rust.

My open source work is split into a few categories:

• Multiple packages for fitting Sorted L1-penalized regression models, including libslope (C++) and its bindings in Python, R, and Julia
• Basin, a Rust library for numerical optimization
• Benchopt, a framework for benchmarking optimization algorithms (and more)

• Moloch, a LaTeX beamer theme for presentations
• Eunoia, a Rust library for generating Euler and Venn diagrams, with bindings in JavaScript, Python, R, and Julia
• Qualpal, a C++ library for generating qualitative color palettes, with bindings in Python and R.
• Tomat, a Pomodoro timer for the terminal

• Panache, a language server, formatter, and linter for Markdown and many of its variants (e.g. Quarto, R Markdown, MyST)
• Fatou, a language server, formatter, and linter for Julia
• Arity, a language server, formatter, and linter for R
• Badness, a language server, formatter, and linter for badness
