My students and I develop software as part of our research, and
some of it exists as reusable tools, libraries, or end-user applications. (The
rest are programs designed for non-reusable purposes, such as for conducting specific experiments.)
The following downloads are posted as-is free of charge, without warranty or guarantee
of any kind. To the best of our knowledge, everything here is bug-free... but you know
how that goes. Please
let me know
if you find something useful.
