My graduate studies and work experience were in numerical analysis and parallel computing, with an emphasis on computer performance on high performance computing (HPC) systems. Specific activities included the following.
a) parallel algorithm design and implementation
My parallel algorithm work ranged from theoretical investigations into what is feasible based on information theoretic concepts to the design, implementation, and optimization of parallel algorithms, most recently in earth system and fusion energy simulation models.
b) performance evaluation of parallel applications and computer systems
