Main

Jonathan Berrisch

I specialized in econometrics for energy forecasting and am well-versed in R, C++, and Python. I currently work in academia between statistics and information technology. I research probabilistic forecasting and maintain a growing IT infrastructure with databases. I also actively contribute to open-source projects and disseminate knowledge by creating beautiful visualizations.
