I am an enthusiast of the ideas of open science and free software, and I have been trying to apply them in the development of tools that help the process of scientific research. Development takes place mainly on GitLab.

All processes involving a computer are (generally) done on my laptop, using the Gentoo Linux operating system, using XMonad or Plasma as desktop environments.

This page was built using the Nikola static website generator, using the default bootblog4 theme, slightly modified by me. All pages are edited using GNU Emacs.


Traditional artworks are usually made with any material at hand. However, some materials that I always try to take with me are:

  • Staedtler Mars Technico 780 2.0 mm 780 C-CA mechanical pencil with HB graphite
  • (for drafting) Pentel GraphGear 500 0.3mm, 0.5mm and 0.7mm pencils with B/2B
  • lead (for pencil finishing) Unipin technical pen 0.1, 0.5, 0.7 and Brush
  • Sketchbook Spiral A6 with Canson paper 100g/m^2

If the drawing is not finalized on paper, it serves as the basis for the digital version. For this I use Krita on my computer as the main tool, drawing with a graphics tablet [Wacom Intuos S](https://www.wacom.com/pt-br /products/wacom-intuos). Some further image processing is done using Inkscape or Gimp. I recently got an iPad Pro 11, and some of the digital work I've been doing on it as well, using Procreate.


Since my research is of a theoretical nature, I don't need much more than paper and pen. However, some tools help a lot in manual work:

  • SageMath for general purpose math calculations
  • Cadabra for tensor calculations
