PROFESSIONAL FOCUS

I am a data scientist with wide expertise in data processing, machine learning, and statistical modelling. My work focused on the analysis of complex data applied to research and policy making. I make strong use of programming languages, mainly R, to create effective and accurate processes for data extraction, analysis and visualisation.
