While carbonate petrology and Paleozoic depositional environments have long been among my research interests, these have until recently served my emphasis on conodont ecology and biostratigraphy. While I continue to work in these areas, I am increasingly involved in studying the nature of carbonate sedimentation and subsequent diagenesis. Click Research Interests for more.
