Leo van Iersel

After studying applied mathematics at the University of Twente, I obtained my PhD at Eindhoven University of Technology. After that, I have worked as a postdoc at the University of Canterbury, as a teacher in primary and secondary schools in Tanzania and Kenya and as a researcher at CWI in Amsterdam. In 2014, I joined TU Delft, where I’m currently an associate professor.

Currently, I do not have any open PhD or postdoc positions.
