Research Interests
My experience running various campus computing centers has allowed me to interact with a wide range of scientific projects in a diverse set of fields.  I've worked with small codes developed by individual researchers, to large, international collaborations with a mature code-base.  I am aware of the many pitfalls associated with the growing-pains of numerical projects, such as going from a single programmer working in isolation, to large groups of developers with varying expertise all working together on the same code base.  I have experience with code optimization, parallelization, regression testing and the various tools necessary to see any scientific computational project succeed.
