Research

Applying formal methods such as model checking and concepts from artificial intelligence, especially preference reasoning techniques, to address problems in requirements analysis for component-based and other compositional systems.

Current work

  • Developing more efficient techniques for identifying conflicting preferences in a conditional importance network (CI-net). Collaborators: Samik Basu (Iowa State), Ganesh Ram Santhanam (Iowa State).
  • Visualizing software requirement preferences and conflicts as modeled in a conditional importance network (CI-net). Past collaborators: Josh Leinberger (UW-W student), Pablo Martinez (UW-W student). Previously supported in part by UW-Whitewater Strategic Initiative grant (Lopamudra Mukherjee, PI).

Recent publications

Links

  • PhD Comics: A Web comic about life in graduate school. Funny and often very true.
  • XKCD: Another Web comic I like.
  • The RISKS Digest: Weekly (or more frequent) summary of computer-related risks to the public, mostly caused by designers and developers (and customers, too) who don't think hard enough about security and safety. Sometimes funny; sometimes rage-inducing. Important reading for those of us who want to see technology used responsibly.
  • Hacker News: Community-moderated news site with news and discussions about technology and anything "that good hackers would find interesting" (where "hacker" means "clever technical problem-solver", not "person who cracks into systems that they're not authorized to access"). The comments are usually as good as, or better than, the posted links. A daily read for me.
  • rachelbythebay : Writing: Stories from an experienced system administrator who has worked in Silicon Valley for many years. Entertaining and informative, especially if you're interested in DevOps, just Ops, or IT work in general. (Note: not much about software development here.)
  • The Jargon Lexicon: An extensive dictionary of hacker slang. Useful for understanding tech people's jokes, and as a window into the history of the field.
  • College radio stations I like: KURE (Iowa State), WSUW "The Edge" (UW-Whitewater), WSUM "The Snake on the Lake" (UW-Madison)
