I'm a member of the Research On Logical Expressivism (R.O.L.E.) group, led by Robert Brandom and Ulf Hlobil. We work on developing a conception of logic according to which logic is, as Brandom puts it in Making It Explicit, "the organ of semantic self-consciousness." For some idea of what that might mean (if this diagram here isn't self-explanatory), check out our website.
As far as my own contributions are concerned, most of them have involved bringing the formalism of billateral logic, proposed by Timothy Smiley and Ian Rumfit, to bear on the sort of logical expressivism proposed by Brandom that is of principle concern to the group. If you'd like to take a look at some of the stuff I've done in this regard (which is all rather rough), feel free to send me an email.
