Software

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 following tools 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.
