My research is focused on analyzing infeasible constraint systems, specifically on extracting information that either points to "causes" of their infeasibility or indicates portions of a problem that are irrelevant to the conflict. Much of this work is implemented in MARCO and CAMUS, both tools for performing such analyses - source code is available for both. See my publications for more details.


Every now and then I make a small script or other program to scratch an itch. I collect these on the tools page in case others might find them useful as well.
