Biography
I am from Seoul, Korea. Currently, I am a Ph.D candidate in Department of Electrical and Computer Engineering. My advisor is Prof. Salim Hariri. My research interests are autonomic computing (self-healing), fault tolerance system, and distributed high performance systems.
I am on the job market this year. Here is the link to my resume.
Current Projects
One of the important design criteria for distributed systems and their applications is their reliability and robustness to hardware and software failures. The increase in complexity, interconnectedness, dependency and the asynchronous interactions between the components that include hardware resources (computers, servers, network devices), and software (application services, middleware, web services, etc.) makes the fault detection and tolerance a challenging research problem. In this paper, we present an innovative approach based on statistical and data mining techniques to detect faults (hardware or software) as well as root-cause analysis of system and application faults. In our approach, we monitor and analyze all the interactions between all the components of a distributed system. We use data mining and supervised learning techniques to obtain the rules that can accurately model the normal interactions among these components. Our anomaly analysis engine will immediately produce an alert whenever one or more of the interaction rules that capture normal operations is violated due to a software or hardware failure. Our analysis show that our approach is superior when compared to other techniques. For example, the precision value that is trained with Tranining with PN equals to 0.998 in 50% noise value and the missed alarm and false alarm rate is near 0%. We also developed algorithms to automatically acquire new rules of the environment and load changes over time.
Our approach is based on autonomic computing paradigm that requires continuous monitoring and analysis of the system state, and then plan and execute the appropriate actions if it is determined that the system is not meeting its requirements.
The overall objective of this research is to investigate key technologies to enable the development of Autonomic Applications that are context aware and are capable of self configuring, self composition, self optimizing and self adapting. Specifically, we will investigate the definition of autonomic components, the development of autonomic applications as dynamic composition of autonomic components, and the design of key services on top of the existing middleware and runtime to support these applications.
