My computer science research interests center on logic-based methods for answering queries
about large bodies of diverse distributed knowledge. I use semantic information,
that is, data about the data, to develop alternative, or cooperative,
answers to queries. In the years since my Ph.D., I have been exploring
problems in computational molecular biology using logic programming techniques
in general and cooperative answering strategies in particular. In collaboration
with genome sequencing groups in Canada, the U.S., and Europe I have built
a system called MAGPIE (Multipurpose Automated Genome Project Investigation
Environment) for analyzing DNA sequence data in real-time during and beyond
the lifetime of a sequencing project.
