Craig Costello

Professor Craig Costello is a leading cryptographer at the Queensland University of Technology (QUT), affiliated with the Faculty of Science and the School of Computer Science. His work focuses on post-quantum cryptography, particularly isogeny-based and lattice-based cryptographic constructions, contributing to global efforts in securing digital infrastructure against quantum computing threats.

Notable research trends include:

• Advancements in supersingular isogeny key exchange (SIKE/SIDH)
• Exploration of pairing-friendly abelian varieties for cryptographic cycles
• Efficient genus 2 isogeny algorithms and Kummer surface optimizations
• Development of twin smooth integer detection for cryptanalysis

His publications emphasize quantum-resistant protocols, mathematical foundations, and practical cryptographic implementations. Contact: craig.costello@qut.edu.au
