I am a senior researcher at the Department of Informatics, University of Oslo and the leader of the Analysis and Complex System Research Program at the SIRIUS Center. My main research area is formal methods for parallel and distributed systems. I have a Young Research Talent grant for a project called ADAPt from the Research Council of Norway, the only grant in computer science for this call in 2017. In this project I am applying static analysis techniques to approximate parallel data access in architectures with shared memory.

I am also doing research on trace-based semantics for concurrent and possible non-terminating programs to enable compositional reasoning about the behavior of distributed systems, and formal modeling concepts for resource usage in distributed systems to analyze resource management and service level agreement.

I have worked in several EU projects including FP7 ENVISAGE, FP7 FET UpScale and FP7 FET HATS. I had a research stay in Imperial College London in 2016 and I was a fellow at the United Nation University, International Institute for Software Technology in Macao China in 2007.

I have taught courses at the master level and I have been supervising PhD and master students. I am PC co-chair of iFM’19 and PC member of FASE’19, ICE'19, F-IDE’19, DISE’19, DEVOPS’18 and DISE’18. I have more than 25 co-authored per-reviewed papers and Journals.
