RESEARCH INTERESTS AND CAPABILITIES

My educational background and work experience are in numerical analysis and parallel computing, with an emphasis on the solution of partial differential equations. My current research interests include:

parallel algorithm design and implementation. My parallel algorithm work ranges from theoretical investigations into what is feasible based on information theoretic concepts to the design and implementation of parallel algorithms in coupled climate and fusion energy simulation models.

performance evaluation of parallel applications and computer systems. My work on performance evaluation has three aspects: (1) performance data collection, visualization, and analysis, (2) benchmarking and benchmarking methodology, and (3) performance modeling and prediction.

software and performance engineering for scientific computing. My software and performance engineering work focuses principally on performance portability, i.e. empirical methodology and software infrastructure that support the quick optimization of performance of a simulation model when problem specification or target computer system changes, and as the model evolves or is ported to a new computer system.
