Padma Raghavan conducts research in high performance computing and its applications. Research by Raghavan's group concerns sparsity as a unifying abstraction toward increasing computational performance defined by metrics such as execution time, parallel speed-ups, energy costs and resilience. Sparse representations of data arise from many different contexts, for example, from largely local connections in a system represented as a sparse graph or network or from partial differential equations models where the number of nonzeroes in an associated matrix is bounded by a small constant times its dimension. Algorithms that exploit sparsity can deliver performance improvements by constant factors to orders of magnitude. Consequently, they enable the solution of larger or more complex problems for computation and data enabled science and engineering "at scale" in a variety of disciplines.
