Welcome to Helge Spieker’s Website

Hi, I’m a PhD Student at Simula Research Laboratory in Oslo, Norway. My work is funded by the Certus Centre for Software Validation and Verification (Certus SFI).

Research Interests

I’m interested in applications of Artificial Intelligence and Machine Learning, especially in the domain of Software Testing. I’m further interested in the integration of Machine Learning and traditional AI methods, such as Constraint Programming.
