Research and Development Engineer10/2010 to 09/2013Ruhr-University BochumBochum, Germany
Ruhr-Universität Bochum Bochum (Germany) Early stage researcher within the international research program AUDIS - Digital Signal Processing for mobile communications in European-union public project.
Proposed and developed novel signal processing algorithms for speech events detection and classification based on extrapolation technique for the future communication systems.
Developed novel algorithm for near-end speech enhancement for mobile communications.

Concept Engineer10/2009 to 09/2010Infineon Technologies AGGraz, Austria
Researched on TPMS (Tire-pressure-Monitoring-System) ASIC flash memory firmware test routines and proposed new DfT (Design-for-Test) concept for reducing the test time and test cost for future hardware solutions.
100 ms test time reduction is proved by implementing and integrating developed DfT concept into the existing flash memory functionality and test time saving was also analysed in terms of test cost.
Integrated proposed DfT concept implemented in VHDL code into the digital core for testing the impact on whole TPMS ASIC functionally.
