I have a broad and interdisciplinary research focus on cyber security, data analytics and digital forensics, where I seek to understand how data can be acquired from contemporary computing devices for both malicious (e.g., criminal / malicious exploitation – cyber offensive) and legitimate (i.e., digital forensics / digital investigation) purposes. The understanding of how data can be acquired (or exfiltrated), particularly in terms of criminal / malicious exploitation, will then inform the design of cyber defensive and privacy-preserving solutions (e.g. using technical approaches such as blockchain and artificial intelligence, and non-technical approaches). I also understand the importance of ensuring my research is relevant to policy and practice, and is aligned with major and ongoing government policy directions and strategies. For example, the cryptographic primitive in one of the three regular U.S. patent applications I filed in 2019 is currently been deployed by a UK cryptocurrency start-up, where I also serve on its advisory board. My patent applications entitled "Lightweight Distributed Signature Protocol For Mobile Computing And IoT Devices" and "Efficient and Secure Distributed Signing Protocol for Mobile Devices in Wireless Networks" were approved on April 19 and November 29, 2022, respectively. 

I have had the opportunity to apply my research knowledge and provide expert opinion on policy developments, such as the Australian Government Department of the Prime Minister and Cabinet’s Cyber White Paper as a member of the Australian Computer Society Cyber Task Force of experts (2011), and the Australian Bureau of Statistics Draft Conceptual Framework for Cybercrime (2012 and 2013). I have also been engaged as an external paid expert to provide expert advice to two companies on their U.S. Department of Energy SBIR/STTR Phase I proposals in 2020 and 2021, and to provide expert insights in writings to inform North Atlantic Treaty Organization (NATO) Allied Command Transformation (ACT) Innovation Hub’s Warfighting 2040 report in 2020. I am also one of two experts involved in the review of the finalized “NISTIR 8006: NIST Cloud Computing Forensic Science Challenges” report.

I also developed the “All About IoT Security” program in collaboration with a number of subject matter experts, as part of IEEE Educational Activities with support from IEEE Internet of Things Technical Community. 

I am serving on the technical advisory board of two U.S.-based start-ups (since Jan 2022), and have been a keynote / plenary speaker at a number of conferences (see Keynotes and invitations presentations), as well as an invited lecturer at the Bangladesh Institute of International and Strategic Studies (2012), Australian Graduate School of Policing and Security (2014), Singapore Polytechnic (2014), Malaviya National Institute of Technology Jaipur (2017), delivered a one week course funded by the Indian Government’s Global Initiative of Academic Networks), and the International School on Internet of Things & Edge AI: Computing, Communications and Systems (2022) at  the University of Calabria in Italy. In 2015, I was an Invited Expert at UNAFEI Criminal Justice (Focus on Investigation, Prosecution, Adjudication, and International Cooperation) Training, at INTERPOL Cyber Research Agenda Workshop, and I was also a Distinguished Speaker at the 1st International Summer School on Computational Forensics (SuCoFo 2016) at Norwegian University of Science and Technology. 

I am the founding co-Editor-in-Chief of ACM Distributed Ledger Technologies: Research and Practice, and the founding Chair of IEEE Technology and Engineering Management Society (TEMS)’s Technical Committee on Blockchain and Distributed Ledger Technologies. I also serve as the Senior Editor of Forensic Science International: Digital Investigation, the Department Editor of IEEE Transactions on Engineering Management, and the Associate Editor of IEEE Transactions on Dependable and Secure Computing, and IEEE Transactions on Big Data, etc. More recently, I was involved as a member of the IEEE Transactions on Big Data - 2020 Best Paper Award Selection Committee and IET Fellow Assessor (see also Other professional activities).

My (limited) media presence is available on Media presentations.


I am the recipient of the following grants: 



Citations of my research include governmental reports: 

One of my published cryptographic protocols was included in two independent submissions to the IEEE 802.11, the working group setting the standards for wireless LANs, by computer scientists from Fujitsu Labs in America; and the Internet Engineering Task Force (IETF) / Network Working Group by a team of computer scientists from Tropos Networks (US), Toshiba, Huawei, and University of Murcia. A protocol jointly proposed with Sherman Chow (formerly of New York University, US) was used in the P2P solution of the Milagro TLS (pairing-based cryptography for Transport Layer Security) presented to the IETF by researchers from MIRACL Ltd in 2016.

My published design principle about how session keys should be constructed in cryptographic (key establishment) protocols that result in significant benefits for their security was cited in a special publication (SP 800-56A) – Recommendation for Pair-Wise Key Establishment Schemes Using Discrete Logarithm Cryptography – by the US National Institute of Standards and Technology. This is one of four academic (i.e. non-NIST and non-international standard) citations, and the other three academic citations are publications of (1) Professor Alfred Menezes (University of Waterloo), Professor Phillip Rogaway (UC Davis), Professor Mihir Bellare (UC San Diego), and Professor Dan Boneh (Stanford University) – the top scholars in the field, and NIST Special Publication 800-56A Revision 3 (April 2018). My cloud forensics research is also cited in the NIST Cloud Computing Forensic Science Challenges report (Draft NISTIR 8006, 2015) and the final NISTIR 8006: NIST Cloud Computing Forensic Science Challenges report.
