Developed a probabilistic multi-tenant model for characterizing performance of a group of workloads (for example, multi-tier applications) serving on modern cloud platforms, such as Amazon AWS EC2.
The proposed model is of great benefit for cloud brokers or small-to-mid enterprises to operate and manage their own cloud services by giving the provisioning balance between performance and pricing
Proposed a greedy heuristic resource allocation (or load balancing) algorithm for achieving best computational performance in cloud computing environment with rigorous proof of the optimality
Resource Allocation in Distributed Systems
Developed and implemented a lattice algorithm, which highly outperformed the previous algorithms in terms of idea clarity, code readability and computational complexity, for solving problems of coupled difference equations
Successfully solved a tricky problem which is to analytically characterize the probability for the first-time consensus by creatively using conditioning method recursively
Cascading Failures in Power Grids
Built a novel continuous-time Markov chain model to understand and approximate cascading failures in power grids. The model embeds the details of physics in power but is still analytical and linear in complexity.
Successfully derived asymptotic analysis on the proposed model by having carefully observed some of the imperceptible features when performing matrix operation
