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. From 2010 t0 2017, I worked at Istanbul Technical University, Dept. of Electronics and Communications Engineering, first as an assistant professor, later as an associate professor. I am currently a research scientist at Analog Devices Inc., Boston, MA, USA. My research interests are in time-frequency frames, sparse signal processing, algorithms for reconstruction problems, and machine learning for signal processing problems. [CV]
