I am a PhD student at the eXascale Infolab University of Fribourg, from March 2017. I hold an engineering degree from SUP’COM (Tunisia). During my university career, I was part of an Erasmus MSc program in 2016 at University of Padova in Italy. My main research interests include large time series analysis, prediction models and crowdsourcing.
