Professional Activities

Infrastructure Development

SSEVOLVE
A flexible C++ code base for calculating stellar and stellar binary evolution. The code's hallmarks include a complete separation between the ODE system to be solved, the input physics, and the implementation of the relaxation-method solver. The code also makes heavy use of virtual classes and inheritance to allow redefinition of the input physics and ODE system in a trivial manner.
XML Vitae
An XML Schema for curriculum vitae and resumes that allows use of a single source document from which, via accompanying XSLT stylesheets, targeted versions of resumes and vitae in different output formats (currently HTML and PDF) may be produced. Based on the XML Resume Library.
