This is the research site of Bernard van Gastel. This site includes academic articles, and background articles. Sometimes I appear in the media, and that is also listed here. I work at the Radboud University, in the Institute for Computing and Information Sciences (iCIS). I work on energy efficient software by creating methods to analyse energy consumption of software, and combine that with research into the effects of digitalization which affects society. Together, I call this Sustainable Software. My non-academic programming work can be found on my Bit Powder site, which include a shared clipboard over SSH utility, and some libraries.
