About me
I am a Computer Science student at the Freie Universität Berlin, currently beginning the second term of my Masters degree. I am further a student scientific assistant at the Fraunhofer AISEC, working on Quantum Algorithms for Cryptanalysis. I have a variety of interests in Computer Science and Mathematics. I also love History, Physics and Chemistry. Currently I am really keen on learning more about
 Writing scientific papers (previously successfully did a dedicated course on it)
 Graph Theory
 Complexity Theory
 Algorithmic Geometry (successfully did a dedicated course on it)
 Quantum Computing and Quantum Mechanics
Posts
For every LaTeXbased article, I have also uploaded the associated code, which can be found on GitHub.

About this page
After hearing about GitHub Pages, I decided to make a small page for some static sites on topics I am currently working with. By now, I have not written a lot, which presumably will not change in the near future.
Unfinished projects
 Computing roots with interval nestings (not finished, 26.09.2020)
 Editing SOC video game save files (not finished, 22.10.2020)

I do not get to update this page very often, so I added a timestamp of the last edit below or if I forget it you can look at the repository https://www.github.com/valentinpi/valentinpi.github.io.
This way of handling the web page is very bad, in some future I will use a more modern way.
