Introduction
I have produced a few papers so far in my career. I have not concentrated on one specific area. Instead I have worked in a number of theoretical areas and several application that are related. The topics include multigrid, numerical simulation of flames, domain decomposition, numerical linear algebra, iterative methods, or esoteric computing methods.
The papers are in chronological order. You may download them in PDF format and view them using the Adobe Acrobat Reader, version 6 or later.

NSF Workshop Reports
Report N1 was used to create the DDDAS part of the ITR program. Report N2 demonstrated that the DDDAS program was a roaring success.

Orphans
These papers stand on their own, but are orphaned. Orphan O1 was accepted for publication by a now defunct German publisher. Orphans O2 and O3 were combined into a single paper, but are clearer in original form. Orphan O4 was deemed too theoretical (truly unbelievable) to publish in SISC.
