Data-driven understanding of energy systems
Benjamin Schäfer
I am a Physicist who turned into a Data Scientist to contribute to our society by supporting the energy transition via data-driven approaches.
In my research, I investigate complex energy systems, using interpretable machine learning to understand, predict and design future energy systems.
Currently, I am an Assistant Professor, leading a group at the Karlsruhe Institute of Technology (KIT) on Data-driven analysis of complex systems (DRACOS).
Research
My goal is to understand complex energy systems from a data-driven point of view, i.e. without assuming too much prior knowledge.
I pay special attention to making any forecast or analysis transparent and explainable, using and developing interpretable machine learning tools. Thereby, I wish to identify drivers and risks for energy systems and help to design future systems, e.g. involving a high share of wind generation, electric cars, heat pumps etc.
