Microsoft Research, Redmond.
About Me
I shortly present my academic and personal interests here. If you are curious and want to know more, just ask me. I have a strong reputation of not biting people.
Researcher
As a researcher, my interest lies in the broad domain of Software Engineering, with a tendency towards its practical applications and empirical studies on software quality and how to improve it. In the TestRoots project, which is the focus of my PhD, I do this by researching Developer Testing. I am also excited about static code analysis, which includes code reviews.
Quality Enthusiast
I am an absolute enthusiast in what I do. During my studies, I already focused on Software Quality. I also was a core committer of the open-source software quality analysis toolkit ConQAT. Consequently, I have a focus on writing maintainable, easy-to-understand source code.
Academic
I studied at Technical University of Munich, Germany, and Linköpings Universitet, Sweden. On top of Software Engineering as my main subject, I chose a research-oriented Master education. I took Sports and Medicine as my minor fields of study.
Sportsman*
In my leisure time, I enjoy sports. After years of competitive table tennis, I have started with Olympic weight lifting and climbing (in the Netherlands!). Besides these indoor activities, I like the mountains. In the winter for skiing, and in the summer for hiking and a bit of mountain biking. From time to time, I go for a run (not really my favored sport, though).
Open-Sorcerer
I am an avid contributor to Open-Source Software (OSS). Besides the OSS projects that I lead myself (TravisTorrent, TestRoots WatchDog, and the AbstractFormatter), I have contributed to the following projects:
- ConQAT, a quality dashboard for software projects. I was a core committer from 2009 through 2013 (Java).
- Unknown Horizons, an Anno 1602-inspired strategy game (Python).
- UAV, a tool that visualizes warnings from multiple automated static analysis tools (Java).
- parsedate, the R library for parsing ISO-8601 (and other) dates.
- Samba, the standard Windows interoperability suite for Unix (C).
- Eclipse, the most-widely used Java IDE (Java).
- Cloc, a popular tool for quickly counting the LoC of a software project (Perl).
- Gitlogg, a tool for making git log parsable (Bash/JavaScript).
- travis-ci-latex-pdf, CI for LaTeX documents.
Linguist
Having a classicist's background (Latinum and Graecum), I like language and speaking in general. From my abroad studies, I have a particular interest in Swedish culture. Besides I like to pay attention to the little language details that matter.
