From February to June 2017, I worked under the supervision of Eva Darulova at the Max Planck Institute for Software Systems (MPI-SWS), in Saarbrücken, Germany. I worked on a static analyser of floating-point programs called Daisy. I extended the formal verification of Daisy, to provide support for mixed-precision floating-point arithmetic. This formal verification consisted in a certificate checker, written in Coq and HOL4.
