Short Bio

I am an Honorary Professor in the Department of Computer Science at the University of Warwick and I am Professor of Distributed Systems in the School of Computing at the University of Leeds. While at Warwick, I led the Reliability and Fault Tolerance group, which is part of the AI theme. My group currently has 6 PhD students. I was previously a Fellow of the Alan Turing Institute.

Research Interests

The central theme of my research is dependability. A system is said to be dependable if trust can be justifiably placed in its correct operation, even in the presence of undesired events (e.g., network failures, malicious behaviours). My current interest lies at the intersection of large-scale distributed systems (e.g., wireless sensor networks, cluster systems), embedded and/or cyberphysical systems and dependability. My work has both an experimental and a formal flavour. I have been increasingly looking at the application of artificial intelligence techniques to the design of dependability.

I have several current research projects in the following areas:

• Reliability and Fault Tolerance
  • Global predicate detection in fault-prone distributed systems
  • Reliable mobile ad-hoc and sensor networks
  • Self-stabilization in distributed systems, including sensor networks and MANETs
  • Design of dependable software systems
  • Dependability in high performance systems
  • Fair exchange
  • Mechanism design
• Application of Machine Learning
  • Error detection/failure prediction in cluster systems
  • Root cause analysis
  • Design of dependable software
• Computer Security
  • Trusted mobile ad-hoc networks (MANETs)
  • Security issues in sensor networks
  • Computer/digital forensics

• Data Science/ support system
  • Dependability-driven design and analysis of large-scale systems
  • Data driven design and analysis of dependable/secure systems and software
  • Data driven design of network protocols for (sensor) networks
  • (Computer/digital) forensics
