Biography

Hagen Wierstorf joined the T-Labs as a research assistant in April 2009. He studied physics at the Carl von Ossietzky University Oldenburg and received his diploma degree in the field of psychoacoustics and neuroscience in November 2008. In September 2014 he received his Doctoral Degree from the Technische Universität Berlin. At the moment he is working in the EU funded project Two!Ears.
