Torsten Hummen, Dipl.-Ing.

Fraunhofer Institute for
Systems and Innovation Research ISI


Work Experience

Torsten Hummen studied mechanical engineering at the RWTH Aachen with a focus on construction and development. He spent an academic year abroad at the Queen's University of Belfast. Torsten Hummen wrote his Diploma-Thesis about "Development of a global energy model to simulate future energy supply structures". During his studies he gained professional experience through internship in the wind power industry and worked as scientific assistant at the Institute of Plastics Processing (IKV). Since November 2012 he has been working as a research assistant at the Fraunhofer Institute for Systems and Innovation Research ISI.
