Work Experience
Massachusetts Institute of Technology (Sept 2007 - Present)
Cambridge, MA
Research Assistant to Prof. Saman Amarasinghe in the Commit Research Group. Developing novel algorithms aimed at simplifying the task of programming, debugging and testing parallel applications by making them run deterministically. Created Kendo, a novel deterministic locking library that efficiently enforces deterministic execution of lock-based parallel applications on today's commodity chip-multiprocessors.
Teaching Assistant for Performance Engineering of Software Systems (6.197). Developed new course material for the first offering of the class.
Sun Microsystems Laboratories (June 2008 - Sept 2008)
Burlington, MA
Graduate Student Research Intern with the Scalable Synchronization Research Group. Created a number of novel reader-writer lock algorithms that are first to scale near-perfectly under read-only workloads without introducing additional space and time overhead when there is little contention. Contributed to SkySTM, a scalable software transactional memory system that efficiently supports implicit privatization.
Google (June 2007 - Aug 2007)
Kirkland, WA
Software Engineer Intern in the Google Video Ads group. Focused on improving targeting of contextual video advertisements for text and in-stream video advertisements. Wrote large-scale distributed programs to examine large amounts of data from various web-based sources to extract information describing the targeted videos.
University of Toronto (Sept 2005 - Sept 2007)
Toronto, ON
Research Assistant to Prof. J. Gregory Steffan in the Department of Electrical and Computer Engineering. Created Judo, a fast and lightweight dynamic binary rewriting system for the x86 ISA. Developed JIFL (JIT Instrumentation Framework for Linux), a tool that allows kernel developers to rapidly debug, profile, and monitor live kernel code through efficient instrumentation performed by a kernel version of Judo. Developed JudoSTM, a dynamic binary rewriting based software transactional memory system. JudoSTM supports arbitrary C and C++ code within transactions, as well as calls to shared libraries and system calls.
Teaching Assistant for Programming Fundamentals, Computer Organization (engsci/enriched offering), and Computer Systems Programming (Head TA, assisted in designing the course).
Microsoft (June - Sept 2005)
Redmond, WA
Intern Software Design Engineer in the Base Class Library Team of the Microsoft .NET Framework. Independently designed and implemented API specifications for new inter-process communication classes. Led numerous group-wide meetings aimed at discussing and obtaining feedback on the design. The work resulted in a patent.
Microsoft (June - Sept 2004)
Redmond, WA
Intern Software Design Engineer in the Common Language Runtime (Microsoft .NET Framework) Port Team. Primarily focused on improving 64 bit performance. Contributed to several components of the runtime, yielding performance increases of up to 45% on certain managed benchmarks. Also ported a working-set analysis tool to the AMD64 architecture.
University of Toronto (May - Aug 2003)
Toronto, ON
Undergraduate Research Assistant to Prof. Michael Voss of the Runtime Optimization for High-Performance Computing Group, funded by the McAllister Summer Fellowship. Developed a framework for automatic install-time construction of empirically optimized parallel sorting algorithms.
