John Stavrakakis

Dr. John Stavrakakis is a Lecturer at the School of Computer Science within the University of Sydney. His research focuses on machine learning, graph algorithms, and 3D graphics optimization, particularly in developing efficient computational methods for spectral clustering, deep learning architectures, and network-aware visualization systems.

• Current research emphasizes random projection techniques for graph convolutional networks and topology-aware clustering methods
• Specializes in 3D graphics streaming and distributed visualisation environments
• Collaborates on network security behavior through computational models of protection motivation

His recent publications highlight innovations in graph construction, k-NN search efficiency, and parameter-free optimization frameworks. Dr. Stavrakakis supervises PhD students including Michael Ashshiddiq Podbury, with expertise spanning data mining, network security, and interactive visualization.
