Dr. Jiangshan Yu (于江山)

Associate Professor
ACS (Australian Computer Society) Fellow

Director, Sydney Blockchain Centre
Director, University Collaboration
Elected Member, IFIP Working Group 10.4
Australian Representative, IFIP TC 10

About Me

I'm an Associate Professor at the School of Computer Science, University of Sydney, serving as the Director of University Collaboration and the Director of the Sydney Blockchain Centre. I'm the Australian Representative for International Federation for Information Processing (IFIP) Technical Committee 10 on Computer Systems Technology, an elected member of the IFIP Working Group 10.4 on Dependable Computing and Fault Tolerance. I'm a Fellow of the ACS (Australian Computer Society).

I'm a recipient of multiple awards recognising my research contributions, including the ACS Fellowship (2025), IEEE TEMS Technical Achievement Award (2024), ARC DECRA Fellowship (2021), IBM Academic Award (2020), and several Best Paper Awards, among others. I have served as Chief Investigator on research projects totaling over 10 million dollars. I serve on the program committees of top-tier dependability and blockchain conferences, including ACM CCS, USENIX Security, USENIX ATC, VLDB, DSN, ICDCS, FC, and AFT. Additionally, I am an Associate Editor for journals including ACM Distributed Ledger Technologies (ACM DLT).

My Journey

I received my PhD in Computer Science from the University of Birmingham (UK), supervised by Prof. Mark Ryan, followed by a postdoc with Prof. Paulo Esteves-Verissimo (IEEE and ACM Fellow) at SnT, University of Luxembourg. Before joining the University of Sydney, I held positions as Lecturer and Senior Lecturer at Monash University, where I served as Research Director of the Monash Blockchain Technology Centre, and was elected as a 2023 Monash Research Talent Accelerator (RTA) Fellow.

What I Work On

My research addresses real-world challenges in building practical systems that prioritise dependability, trust, security, privacy, and scalability. I design robust, high-performance digital infrastructures by leveraging dependable computing, decentralised systems, cryptography, and security protocols.

Impact

My research has advanced the resilience and performance of blockchain systems and services, with findings adopted by major blockchains such as Ethereum, Monero, Nervos, and NEO. I have also developed security protocols adopted by exchanges and wallet services to better protect their user assets. Beyond industry impact, my work has supported governments in advancing digital transformation and cybercrime investigations, contributing to research-informed policy-making in practice.
