### Author Details

David W. Lewis

The research interests of Professor Lewis are in the general areas of algebra and topology, and more specifically in the algebraic theory of quadratic and hermitian forms, and in the theory of algebras with involution. He was manager of the Dublin branch of the European Union TMR network on "Algebraic K-theory and Linear Algebraic Groups" 1997-2002, and is currently manager of the Dublin branch of the European Union Research Training Network KTAGS on "K-theory, Linear Algebraic Groups and Related Topics" 2002-2006. He co-organized international mathematics conferences on "Quadratic forms and their applications" in UCD, 4 -11 July 1999, and on "K-theory, algebraic groups and related structures" in UCD, 5 - 8 July 2004.
