Director

Drew Moshier, Professor of Mathematics and Computer Science, has been at Chapman University since 1994.  His research interests include real number computation, bitopolopgical spaces and their applications in logic and information theory, and computational linguistics.

Full-time Faculty

Michael Fahy, Professor of Mathematics and Computer Science, is interested in computational methods for generalizing the Ore condition to explore the structure of localizations of non-commutative rings.

Peter Jipsen, Professor of Mathematics, is an expert on algebraic logic and ordered algebraic structures. He is particularly interested in residuated lattices, including Linear logic algebras, Basic Logic algebras, MV-algebras, lattice-ordered groups and relation algebras, as well as lattices and semilattices with operators in general.

Founding Members

Frederick K. Dashiell, Jr., Ph. D. in Mathematics, Visiting Scholar at UCLA. Dr. Dashiell investigates areas in pointfree topology, lattice theory, topological questions related to computer science, rings of continuous functions, descriptive set theory, and Banach space theory. The interplay between algebra and topology remains a long time theme in his research.

Joanne Walters-Wayland, Ph. D. in Mathematics. Research interests include frames (locales), σ-frames, Lindelöf frames and other aspect of point-free topology.

External Members

	Rick Ball, Professor of Mathematics, University of Denver
	Bernhard Banaschewski, Emeritus McKay Professor of Mathematics, McMaster University, Canada. Current research involves (1) various aspects of pointfree topology including compactification, essestial completion, and rings of real- or integer-valued continuous functions, (2) lattice-ordered groups and rings and their interaction with pointfree topology, and (3) the realation of the Axiom of Choice and the Prime Ideal Theorem to results in these areas.
