Hi there, my name is

Lucas Beyer

I'm a self-taught hacker and studied scientist dedicated to the creation of awesomeness
currently living, working, loving and playing in Zürich, Switzerland.
Awesomeness: noun (a) Helping robots understand the world (b) Helping humans understand deep learning.


«Les études, l'arme standard du pays qu'on a du mal à faire tirer, donc on s'éduque seul.» - Alonzo









I also try to contribute back to most Open-Source projects that I use.


(TODO: This is all quite old!)


Articles are lengthy writeups supposed to teach you something if you take the time to fully read them.


Snips are short, roughly screen-sized solutions to problems I encountered which I share in the hope they'll save someone time.

  • Jointly supervised by Prof. Paolo Bientinesi, PhD and Prof. Dr. Stefan Bluegel at the AICES, RWTH Aachen University and the PGI-1/IAS-1, Forschungszentrum Jülich.
  • The aim was to implement a flexible DFT simulation system which allows researchers to quickly prototype new simulations on their laptop and then run those on a supercomputer without much additional overhead.
  • I didn't finish this PhD and changed into the field of computer vision, simply because quantum physics weren't fun to me.

Dipl.Ing. Student in Computational Engineering Science

  • At RWTH Aachen University (Germany)
  • Graduated as a Dipl.Ing. with a grade of 1.3.
  • Obtained state-scholarship in the years 2010 — 2011.
  • Project thesis: Data-based modelling of protein-protein interaction, graded 1.3.
    • This involved highly optimized brute-force search for patterns as well as optimization based on genetic-algorithms.
  • Final thesis: Exploiting Graphics Accelerators for Computational Biology, graded 1.0.
    • This was about solving a generalized least-squares problem (ANOVA) for huge amounts of data on the GPU.
    • This necessitates tricks such as triple-buffered processing and making use of multiple GPUs.

You can contact me by appending gmail's domain to this hostname, or running the following Julia statement:

join(["lucasb", "eyer", "be", join(["gmail", "com"], '.')], '.', '\u40')

Or, if you're more of a Pythonista (or just lazy), the following one is pretty similar:

'.'.join(['lucasb', 'eyer', '\x40'.join(['be', 'gmail']), 'com'])

In case you wonder what I look like, so we can sit down for a (Belgian) beer should we ever encounter, this is me.
