My research is focused primarily on early Paleozoic biotas and their relationships to environmental changes. This time interval embraces some of the most significant evolutionary events in Earth history, setting the agenda for life as we know it. I work chiefly as a micropalaeontologist. Our "tools of the trade" comprise fossils in the microscopic size range that are extracted from their enclosing rocks in great abundance. Subsequently these fossils are studied to assist us in understanding ancient ecosystems and solving various geological problems. At the present my major research projects are on: (1) Paleozoic jaw-bearing polychaetes - palaeobiogeography, palaeoecology, taxonomy and evolution; (2) Cambrian faunal dynamics, exceptional preservation, biostratigraphy and event stratigraphy; (3) Diet and trophic structures in ancient ecosystems, and (4) Middle Ordovician high-resolution biostratigraphy and faunal dynamics.
