Ron's research introduced structured lattice problems, in particular, the Polynomial-LWE problem (a common variant of Ring-LWE) and established their quantum security foundations and cryptographic applications. He also established the first quantum security foundations for NTRU-based encryption and signature algorithms. Variants of these structured lattice problems and algorithms are now routinely used in practical lattice-based cryptography, including the NIST Post Quantum Cryptography (PQC) standard algorithms Kyber, Dilithium, and Falcon. He was awarded the ASIACRYPT 2015 best paper award for Rényi divergence based analysis techniques bridging a gap between theory and practice in lattice-based cryptography, which form the basis for practical implementations of lattice-based cryptography. He has over 20 years of research experience in cryptography and information security. He has published more than 80 research papers in international refereed conferences and journals, more than 10 of which have each been cited over 100 times.  He received more than AUD$4M in research and consulting funding,from organisations including Australian Research Council, Data61/CSIRO, and the cybersecurity industry. He has served as Technical Program committee member in numerous top-tier international research conferences worldwide (EUROCRYPT, CRYPTO, ASIACRYPT), has been an editorial board member of journal Designs Codes and Cryptography (2017-present), and consulted in cryptography design for the software industry.

Research interests

Ron's main research interests are in the design and analysis of cryptographic algorithms and protocols, and the formulation and proof of their security properties. He is especially interested in the area of quantum-safe cryptography and its applications.
