Deptartment of Computer Engineering
Sharif University of Technology

I received a Bachelor of Computer Engineering at Shiraz University (2010) and an MSc in Computer Engineering at the Sharif University of Technology (SUT) (2012). I am currently a Ph.D. student and a member of the Speech Processing Laboratory at SUT.

My research interests focus on Speech Processing, Pattern Recognition and Machine Learning. My previous research in MSc was Speaker Identification. In Ph.D., I mainly focused on Robust Speaker Verification. In addition to academic research, I have been working in Asr Gooyesh Pardaz company since 2011.
