Welcome to my academic homepage! I'm a Ph.D. candidate in Computer Science, at the University of Toronto. My research interests lie in the areas of: storage reliability and performance, file systems, operating and distributed systems, systems modeling and simulation, databases, and networks.
My current research objective is to enable collaboration between tasks that access the same large body of data, either for data analytics purposes, or as part of maintenance. Such tasks may range from MapReduce jobs to backup, virus scanning, and layout reorganization. In this context, collaboration is possible by adjusting the tasks' data access patterns in a manner reactive to other tasks running in the system. This enables tasks to leverage data availability in system caches, and collectively reduce the I/O needed to reach their goals, which in turn reduces their runtime.
