Dr. Thomas Brenner

Dr. Thomas J. K. Brenner studied Interdisciplinary Sciences at ETH Zurich (Switzerland) and obtained his PhD from the University of Cambridge, UK with a thesis on device physics of polymer solar cells.

Afterwards, he was a Postdoctoral Research Associate at the Max Planck Institute for the Science of Light in Erlangen in the Nano-Optics group of Prof. V. Sandoghdar. Before joining Dr. Langniß Energie & Analyse, he led an independent junior research group within the Helmholtz Energy Alliance for Hybrid Photovoltaics at the Institute of Physics & Astronomy at the University of Potsdam.

At Dr. Langniß Energie & Analyse he works as a project leader working on the economic implementation of renewable energies and Smart Grids both in Germany and worldwide.
