Projects
My projects translate cryptographic research into practical technologies for trustworthy digital systems, with current work spanning blockchain privacy, digital finance, threshold cryptography, and post-quantum security.
Current projects
Implications of Cryptocurrencies for the Pacific
Role: Primary Chief Investigator
Period: May 2026 – February 2027
This interdisciplinary project examines the implications of cryptocurrencies for Pacific Island countries. It considers how digital assets and related financial technologies may affect economies, institutions, communities, and policy development in the region.
NextGen Blockchain Privacy & Security: Practical and Quantum-Safe Solutions
Role: Chief Investigator
Period: January 2026 – January 2029
Funding: Australian Research Council, A$557,398
This project develops practical and quantum-safe cryptographic tools for blockchain privacy and security. Its research includes confidential transactions, secure digital wallets, and privacy-preserving payment channels, aiming to improve the security, efficiency, and trustworthiness of digital payments.
Efficient Weighted Threshold Signature
Role: Chief Investigator
Period: September 2025 – September 2026
This project investigates efficient weighted threshold-signature mechanisms, where participants can hold different signing weights. Such mechanisms support flexible and accountable joint authorisation for distributed digital systems.
Completed projects
More Efficient and Scalable Post-Quantum Multi-Signatures
Role: Chief Investigator
Period: August 2024 – December 2025
This project investigated more efficient and scalable multi-signature schemes designed for the post-quantum setting. It contributes to the development of cryptographic tools that can remain secure against future quantum-computing threats.
