In 2019, I started a PhD with Andreas Krause at ETH Zürich, and Nicolas Usunier and Gabriel Synnaeve at Facebook AI Research.
In 2012, I finished my Master's degree at the Karlsruhe Institute of Technology, focussing on Machine Learning, Cognitive Systems and Theoretical Computer Science. In my final thesis, I applied deep learning techniques to feature preprocessing in automatic speech recognition. With support from my advisors, Alex Waibel and Florian Metze, as well as from InterACT, I was able to perform my thesis at Carnegie Mellon University in Pittsburgh, PA.
In 2009, I finished my undergraduate studies in Computer Science at the University of Freiburg. I wrote my Bachelor's thesis, "Intelligente Objekterkennung für ein lernfähiges Carrerabahn-System" at Prof. Martin Riedmiller's Machine Learning Lab. It documents the development of an intelligent object tracking system for Prof. Riedmiller's NeuroRacer, a reinforcement learning slotcar system.

Starting from 2016, I am a Research Engineer at Facebook AI Research (FAIR), initially working on neural machine translation and for some time now on reinforcement learning for games.
In 2013 I worked for Mobile Technologies, which offers speech-to-speech translation for smartphones via the Jibbigo app. In Fall 2013, we were acquired by Facebook and bootstrapped its speech recognition and machine translation efforts.
Throughout my studies, from 2006 to 2012, I've been working at Phönix PACS, a Freiburg-based company producing PACS software. I mainly worked on 3D reconstruction and visualization of medical image data as well as segmentation and analysis of anatomical structures.
Here are some of my projects that are publicly available as free software:
- rsvndump, a remote Subversion repository dumping tool
- pepper, a scriptable source code repository statistics and report tool
- qmpwidget, a Qt widget for embedding MPlayer
- hcxselect, a CSS selector engine for C++ working with htmlcxx
- pgpry, an OpenPGP private key recovery tool using Pthreads
- qICCreator, a simple IC drawing application (out of date)
- cstune, a command-line audio player with a small number of features
- Many programs for graphing calculators, including games as well as utility programs written in TI-BASIC and C.
On rare occasions, I stick with existing software instead of re-inventing the wheel. Here are some patches I've submitted:
- Support for custom URL scheme handlers for the Arora web browser
- Custom button actions for menus and icons for PieDock, a pie-shaped task bar and application launcher for X11
- Support for HTTP "Referer" field for the VLC media player
- Interactive desktop switching in Openbox. The patch wasn't applied, but fortunately the behaviour is the same now.
- Slides from a talk about Haskell arrows (in German)
- Beginner's tutorial for C programming on TI 68k calculators (in German). The English translation of the first parts can be found here.
- Small article on gray-scale graphics on TI 68k calculators (in German)
- How to setup Laudio with lighttpd describes the setup of a web-based audio player using the lighttpd web server.
I used to be an active member and administrator at the largest German message board about graphing calculators from Texas Instruments, mobifiles.de. During that time, Martin Huber from mobifiles.de and I founded boolsoft.org, an open-source programming group for TI 68k calculators. However, I've been rather inactive at calculator programming for the last couple of years.
