Short Bio

Nils Bornhorst received his diploma in electrical engineering and information technology (Dipl.-Ing.) from Technische Universitaet Darmstadt, Germany, in August 2009. From September 2006 until February 2007, he studied at ENSIEG (Ecole Nationale Supérieure d'Ingénieurs Electriciens de Grenoble) of the INPG (Institut National Polytechnique de Grenoble), France. In September 2009, he joined the Communication Systems Group at Technische Universitaet Darmstadt where he is now working towards his PhD.
