I received the BSc., MSc. degrees in EEE from Middle East Technical University, Ankara, Turkey, and the PhD degree in EE from Polytechnic Institute of New York University, Brooklyn, NY. After spending a year with the Biomedical Imaging Group at EPFL, Switzerland, as a post-doctoral researcher, I joined Istanbul Technical University (ITU), Dept. of Electronics and Communications Engineering, as a faculty member. I served as a faculty member (assistant/associate professor) at ITU for seven years. Following that, I worked at Analog Devices Inc. (Boston, MA, USA) and Siemens (Princeton, NJ, USA) at a senior/staff research scientist positions. I am currently a staff signal processing engineer at Whoop Inc., Boston, MA. My past research interests spanned time-frequency frames, sparse signal processing, algorithms for reconstruction problems, estimation/tracking and machine learning (deep or classical) for signal processing problems, covering applications on audio, microphone arrays, radar, and biomedical signals.
