Accepting PhDs



Dr. Edward Chuah is a Lecturer (equivalent to Assistant Professor in the US) in the Computing Science Department, University of Aberdeen.  He received his PhD in Computer Science at the University of Warwick (His PhD supervisor was Dr. Arshad Jhumka).  Before his PhD, he worked in Singapore as a research engineer, software engineer and lecturer (1.5 years in software engineering, 8 years in R&D and 2 years in teaching).  After his PhD, he continued his research in failure diagnosis and developed new research in network security as a post-doc at Lancaster University (His advisor was Prof. Neeraj Suri).  He also taught at the University of Exeter.  His current research focus is in High-Performance Computing (HPC) systems failure diagnosis and identifying attacks in large networks.  He has been working on the topic of failure diagnosis since 2010.  His work involves processing large volumes of real data to generate new insights into a distributed system and to improve its reliability and security.

Research topics: Large-scale systems dependability, Network security (attacks identification), HPC reliability (failure diagnosis, failure prediction, error propagation and error detection), Data analysis.

Prospective research students:  If you are interested in studying for a PhD in one of the aforementioned research topics, then email your CV, academic transcripts and proposal to Dr. Chuah at thuan.chuah@abdn.ac.uk for an informal discussion.

Research Overview

Research interests:

Edward's main research interest is in large-scale systems dependability.  His initial research interest is focused on reliability [1-5], one of the attributes of dependability.  Currently, his focus is on the security aspect of dependability where he investigate security in large networks [6].  He also has a general interest in machine learning, anomaly detection, causal inference and software security.


Edward's expertise is in system failure diagnostics and data analysis.  He is the main developer of FDiag, a system log-based failure diagnostics toolkit [5].  FDiag has been used by HPC systems administrators at the Texas Advanced Computing Center to uncover previously unknown causes of compute node soft lockups.  He also developed several more system log-based diagnostics tools.  ANCOR is a novel anomaly-correlation approach that linked system resource usage anomalies with system failures [4].  CORRMEXT is a new workflow that identified patterns of error propagation on large supercomputer systems [2].  FDiag, CORRMEXT, etc. are available on GitHub.
