Specialization in sedimentary geochemistry with applications to paleoceanographic and global systems analysis.  Research is directed along three broad themes: Environmental change at the Permian/Triassic boundary, the relationship of land plant evolution to weathering rate changes and global events during the Middle to Late Devonian, and the development of trace-metal redox proxies to study paleomarine systems.

Dr. Brett's research focuses on relating regional and global changes in sea level, climate, and the carbon cycle to episodes of biotic change (bioevents) and extinction, and time-specific sedimentary facies. Projects involve establishing regional and global patterns of Paleozoic sequence stratigraphy and relating them to prolonged intervals of relative biotic stability, or "coordinated stasis", and episodes of abrupt change. He also maintains active research in taphonomy, including comparative fossil preservation and modern experimental approaches designed to test the concept of taphofacies, pursuing studies of ancient organism interactions including organism-substrate relationships and the mid Paleozoic predator revolution, and the paleobiology of marine invertebrates, especially echinoderms and arthropods.

I study the ecological information contained in natural accumulations of bones (death assemblages). Through a multidisciplinary approach that brings together ecology, wildlife management, conservation biology, paleobiology, and GIS, my research explores the ecological data contained in bone accumulations from the modern, sub-fossil, and fossil realms. Using fieldwork, quantitative analyses, and statistical modeling, I am refining our understanding of the biological data that is contained in bone accumulations and providing new tools for recovering those data from recent, historical, and fossil accumulations.

My research program examines the response of biological communities to environmental and human stressors. The sustainability and integrity of ecological resources are increasingly uncertain as climate warms and Earth faces a biodiversity crisis. To remedy this situation, scientists must understand the magnitude, direction and rate of biotic responses to environmental and human impacts. However, environmental and anthropogenic factors operate simultaneously and therefore, they are difficult to discriminate using short-term ecological/human-lifespan scales. My work incorporates a longer-term (geological) dimension through three sequential intervals in the recent geologic past: (1) before humans, which I study with paleontological records, (2) during aboriginal (pre-industrial) occupation, by investigating archeological sources; and (3) in post-industrial times, by measuring modern and historical ecological records. The group of organisms I use to examine biotic-environment-human interactions belong to the Phylum Mollusca (primarily terrestrial gastropods) because they are plentiful, sensitive to environmental and human interference, and less investigated yet more threatened than other present-day major animal groups. To investigate molluscs, I integrate data and techniques from multiple disciplines including isotope geochemistry, taphonomy, paleoecology, Quaternary geochronology, archeology and the emerging field of conservation paleobiology.
