    Stanley B. Hanke received a B.S degree in Electrical Engineering with Honors from Georgia Institute of Technology, Atlanta, GA, in 2012. He is an active member of IEEE and Eta Kappa Nu.

    At Georgia Tech, Stan split his time between Embedded Systems Design and Control System Theory. Having participated for 3 years at the IEEE SoutheastCon Student Hardware Competition, Stan has led teams to design and build several robotics projects. Having proficiency in both hardware design and layout, and also software program development, he is able to manage and assist in both aspects on large projects. He also spent two summers working as a co-op for Texas Instruments in Houston, first working as an Applications Engineer helping to develop software and assets to support the C-6000 line of TI DSP processors, and then working as a Product Engineer, where he focused on COB reduction and testing efficiency for processors in the TI multicore product line. His work at TI as a PE resulted in direct multi-million dollar savings from testing costs on several 4x and 8x DSP core processors.

    At iWINLAB, Stan used his expertise in digital architecture design to implement wireless systems and digital video compression in hardware. His skills working with FPGA devices and HDL device development have been assisting iWINLAB in prototyping and testing designs and algorithms based on our research.

    Stan is currently employed by DeLoitte working on Cybersecurity engineering and analysis.
