Research Assistant, Istanbul
Technical University
July 2011 – June 2012
Project Title: Audio processing with sparse regularisation
funded by The Scientific and Technological Research Council of Turkey.
• We developed an inverse problem formulation for multilayer decomposition of
audio signals. To solve this problem, we used convex optimization.

¨ IEEE Communications Society Student Branch
• I served as the Chairperson of IT
between 2009-2010. I organized and gave short courses titled “Programming with
MATLAB” to undergraduate students of the Communications Engineering De˙ U.
¨
partment at IT
• When I was an undergraduate student, I gave high-school level geometry lectures
to students who could not afford University Entrance Exam preparatory schools.
My friends and I did this in a nonprofit student organization and gave lectures
totally free of charge.
