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

For every LaTeX-based 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

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.
