Curriculum Vitae and List of Publications

BOOK: "TOPOLOGICAL METHODS IN GROUP THEORY":

My book "Topological Methods in Group Theory" is Volume 243 of the series Graduate Texts in Mathematics (Springer 2008). For the book's home page click here.
To order from Springer click here. To see a table of Contents, click here.

BOOK: "THE ART OF PROOF":

This textbook, written with Matthias Beck, is published in the Springer series Undergraduate Texts in Mathematics. It is written for a one-semester course for undergraduates who are learning to read, write and do mathematics at a professioinal level. Usually, the course is taken after calculus and before analysis and abstract algebra. For the book's home page click here.

RESEARCH INTERESTS:

Topology, geometric group theory, fixed point theory, dynamics.

My primary field of expertise is topology. Within that large area I am particularly interested in the interplay between group theory and geometry/topology. Names of subfields create artificial boundaries in mathematics and I dislike them. But, with that disclaimer, my interests have led me in recent years to work in: geometric and homological group theory, fixed point theory, and certain parts of dynamical systems. Some of the questions motivating this work are algebraic, involving the algebraic K-theory of rings associated with the fundamental group; this is how I got interested in Nielsen fixed point theory, particularly parametrized versions of that theory. Other questions are about how an action by a discrete group on a non-positively curved space can lead to group theoretic information. I'm also interested in understanding the algebraic topology invariants of a group which come from studying the "end" of the universal cover of a suitable classifying (aka K(G,1)) space. There's a vein of information here that has not been mined. This is one of the themes of the above-mentioned book.
