About Alexandre

Alexandre is passionate about meteorology since its young age. He realised a first internship at Meteo France at the age of 13. Since then he specialized in oceanography and meteorology with a strong numerical pattern. After a PhD in numerical modelling of fine scale wind hazards at Meteo France research center (CNRM – Toulouse, France) he continues with a PostDoctoral project at Mines Paris – PSL on wind resources assessment. In the Observation Impact Energy research center he started working on solar forecasting. He’s been working on this subject for 10 years now focusing on data science.
