Ph.D. in Information Security and Communication Science
Norwegian University of Science and Technology (NTNU)
Thesis Advisor : Prof. Christoph Busch
Ali Khodabakhsh obtained his B.Sc. degree in Electrical Engineering from University of Tehran, Tehran, Iran, in 2011, and his M.Sc. degree in Computer Science under the supervision of Dr. Cenk Demiroğlu from Özyeğin University, Istanbul, Turkey, in 2015. During his M.Sc. studies, he worked on Automatic Speech Recognition, Automatic Speaker Verification, Spoofing Automatic Speaker Verification Systems, and Speech Based Assessment of Alzheimers’ Disease. He coauthored a book chapter, 4 journal papers, and 7 conference papers during this time. He also 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 Laboratory of Informatics of Grenoble (LIG), Grenoble, France, during summer 2015.
