The Exelixis Lab
Unlike in Biology, conference publications are much more important in computer science. We normally submit full papers to conferences which are then peer-reviewed and appear in printed conference proceedings or on CDs. If you look at the publication record of CS professors (for a representative example have a look at the homepage of Dimitris Nikolopoulos) you will find that they typically have much more conference than journal publications.
