Research Interests

Dimitris currently pursues a PhD in AUEB under the supervision of Associate Professor Themos Stafylakis. His research interests include audiovisual deepfakes and audiovisual deepfake detection, biometric verification with a focus on face recognition and speaker recognition.

PhD research on "Synthetic Speech Source Detection using Metric Learning"
Abstract: This study investigates synthetic speech source tracing by adapting speaker recognition methodologies. Experimental results demonstrate that a ResNet-based, metric-learning pipeline achieves performance competitive with, and at times superior to, self-supervised learning systems. These findings underscore the efficacy of ResNet architectures for audio forensic analysis of manipulated media.
