Among the early areas of my interest was the performance of BLAS kernels and their usage in single processor and parallel solvers for large dense linear systems. I have also looked into the effects of using Strassen's matrix multiplication algorithm in the blocked algorithms for these problems. Recently, I have worked with S. G. Sedukhin. The topic was generalization of matrix multiplication (and its applications). Obtained results have been summarized in the following publications (all papers listed here are "Technical Report" quality and copyrighted originals should be used for all purposes over and above plain curiosity):
