Hanen OCHI Research Professor and Head of the Master Program in "Business Intelligence and Analytics"

I obtained my Ph.D. in Computer Science from the University Paris 13 in December 2015. I then held  a Teaching and Research Associate position at Galilee Institute (teaching institution) and LIPN (The Computer Science Laboratory of Paris-North University ). After that, I was an R & D engineer in Big Data and worked on various innovation projects (autonomous cars, predictive analysis, opinion mining).

I am currently working on combining my dual expertise in the model-based process analysis with data-oriented analysis by mixing the data science algorithms with formal verification techniques to to relate data to process analysis. My research focuses on the development of principle approaches to data analysis, data mining and formal verification and their application to diverse areas including process mining, healthcare, service oriented architecture etc.
