Felienne Hermans

Felienne is assistant professor at the Delft University of Technology. Her dissertation explored the idea to treat spreadsheets as source code and apply methods from software engineering, like refactoring and testing, to them. In 2010 Felienne founded Infotron, a startup that uses the algorithms developed during her PhD project to analyze spreadsheet quality for large companies. In her spare time, Felienne volunteers as a judge for the First Lego League, a world wide technology competition for kids.
