I received the BSc., MSc. degrees in EEE from Middle East Technical University, Ankara, Turkey, in 2002 and 2004 respectively. I received the PhD degree in EE from Polytechnic Institute of New York University, Brooklyn, NY, in 2009. In the following year, I was with the Biomedical Imaging Group at EPFL, Switzerland, as a post-doctoral researcher. In 2010, I started working at Istanbul Technical University, Dept. of Electronics and Communications Engineering. I am currently an associate professor in the same department. My research interests are in time-frequency frames, sparse signal processing, algorithms for reconstruction problems, as well as machine learning for signal processing problems. [CV]
