About Me

Ali KhodabakhshAli Khodabakhsh obtained his B.Sc. degree in electrical engineering from the University of Tehran in 2011. He received his M.Sc. degree in computer science under the supervision of Dr. Cenk Demiroglu from Ozyegin University, Istanbul, Turkey, in 2015.

During his M.Sc. studies, he worked on Automatic Speech Recognition, Automatic Speaker Recognition, Spoofing Automatic Speaker Recognition Systems and their Countermeasures, and Speech-Based Assessment of Alzheimers’ Disease. He contributed to the Spoofing and Anti-Spoofing (SAS) corpus, and consequently the Automatic Speaker Verification Spoofing and Countermeasures Challenge Special Session at Interspeech 2015 conference. He was an intern researcher under the supervision of Prof. Laurent Besacier in the Laboratory of Informatics of Grenoble (LIG), Grenoble, France, during summer 2015.

He is currently a Ph.D. candidate at Norwegian Biometric Laboratory (NBL) at Norwegian University of Science and Technology (NTNU) under the supervision of Prof. Dr. Christoph Busch.

His research interests include speech and face biometrics, speech and video processing, and deep learning.
