RESEARCH INTERESTS

Much of my  past work has centered around software for solving challenging applications problems in computational fluid dynamics, combustion, atmospheric modeling and lubrication modeling, together with the development and analysis of the underlying algorithms..

Partrticular research Interests are 
  • Software Abstractions for Extreme-Scale Scalability of Computational Frameworks
  • Extreme-scale parallel solution of complex science and engineering problems
  • Runtime systems for DAG-based software at extreme parallel scales.
  • The Mathematics of the Material Point Method
  • Analysis of numerical methods and adaptive computational algorithms in scientific computing
  • Interdisciplinary solution approaches to challenging applications
  • High performance solution of large graph-based applications

My research is concerned with developing algorithms and software for the solution of challenging science and engineering problems both serial and parallel computers. Much of this research at present involves the use of the Uintah computational framework on a number of challenging example cases from combustion and multi-scale materials science. For example, the uintah code was used to solve complex engineering problems on some of the fastest and most powerful computers in the world.
