About Me

I am a PhD Candidate at Cheriton School of Computer Science, University of Waterloo under the supervision of Professor Bernard Wong and Professor Khuzaima Daudjee. I have completed my BCS and MMath at University of Waterloo in 2013 and 2015 respectively.
My research interests include distributed systems, cloud computing, distributed storage systems and software-defined networking.

Projects

MicroFuge Performance Isolation in Cloud-based Storage Systems.
Cloud computing has significantly improved resource utilization by having multiple tenants share the same resources. However, this reduces the isolation between tenants which may lead to inconsistent and unpredictable performance. Providing predictable performance is particular important for cloud storage systems because they are the performance bottlenecks for many cloud-based services. MicroFuge is a new distributed caching and scheduling middleware that provides performance isolation for cloud storage systems.
