I retired in 2008, and I now have the title 'Emeritus Professor'. A second edition of Markus Brodmann's and my book 'Local cohomology: an algebraic introduction with geometric applications' was published in November 2012.

My research interests are in commutative algebra. Some of my fairly recent work (such as papers 68, 70, 72, 73, 74, 75 and 83 in my list of publications) has resulted from enthusiasms and ideas generated during the writing (with Markus Brodmann) of the book on 'Local cohomology'. A second edition of 'Local cohomology' has now been published. Other fairly recent work (see papers 65, 69 and 77) concerns linear growth of primary decompositions, and connections with tight closure (see paper 77). My most recent work is concerned with use of the Frobenius skew polynomial ring in the theory of tight closure and Frobenius closure: see papers 78, 79, 80, 81, 82, 84, 85 and 87. Preprints are placed on the Commutative Algebra arXiv after acceptance for publication.
