My research interests center upon developing a multidisciplinary understanding of ancient life during key intervals in earth history. I am especially intrigued by the interplay between animals and environments (particularly animal-substrate-microbe interactions) and the role of metazoans as ecosystem engineers in both modern and ancient settings. I am also interested in the processes of fossilization and the role preservational processes play in modifying the stratigraphic records of both ecosystems and environments. My research is heavily field- as well as laboratory-based.
I am currently investigating the biogeochemical, taphonomic and diagenetic pathways responsible for the exceptional silicified preservation of Ediacaran and lower Paleozoic soft-bodied faunas (‘Ediacara-style’ preservation), using a combination of field-based, paleontological, petrographic, experimental and geochemical techniques.
Other research interests include the advent and development of infaunal mixing by burrowing animals in the early Paleozoic; modern marine microbialite-infauna interactions; Ediacaran taphonomy and paleoecology; turnover between Ediacaran and Cambrian faunas; and the role of environment, taphonomy and tracemaker diversity in the formation, preservation and distribution of trilobite-produced trace fossils such as Rusophycus and Cruziana.
