Biography
Karim Helwani studied Computer
and Communication Technology at the University of Saarland and carried
out his diploma’s degree (Diplom Ingenieur) in 2007 on (Inverse
Scattering Algorithms for Coupled High Frequency Transmission Lines),
from summer 2007 to 2008 he was research associate at the Audio
Communication Group of the TU Berlin and worked additionally as
embedded systems engineer at PikeTec GmbH in Berlin.In Summer 2008 he
was employed at the institute of Microelectronic Systems at Leibniz
University Hannover, where he held classes in System Architecture for
Adaptive Music Classification. He joined Deutsche Telekom Laboratories
in November 2008.
