George Fourtounis

I am a Software Engineer at GRNET.

Before that, I was a Research Associate at the PLAST lab of the Department of Informatics and Telecommunications, University of Athens. I also taught Advanced Programming Techniques (fall 2016).

I finished my PhD in 2014, at the National Technical University of Athens (NTUA). I worked on gic, a compiler from a subset of Haskell to dataflow, based on the intensional transformation technique.

Research interests

• dataflow languages and intensional programming
• functional programming languages, type theory
• program transformation
• program analysis
