The goal of my research is to study ecological responses to natural and anthropogenic environmental disturbances. In particular, I use the fossil record as a natural laboratory to test ecological and evolutionary responses that operate at timescales beyond direct human observation and I determine the pristine ecological baseline of modern ecosystems in need of conservation or restoration. Research approaches that I employ include:
- Geographic Information Systems (GIS) and PaleoGIS, including the study of how abiotic and biotic factors govern species distribution and species invasions in deep time.
- Evaluation of multiple stressors on ecosystems, including commercial fishing, eutrophication, and hypoxia, by combining modern geochemical evidence with that from live (and recently dead) organisms, archaeological shell middens, and Holocene fossils.
- Stable isotopes (N and C) to evaluate trophic position.
- Morphometric analyses to study placement of predatory drill-holes to investigate changes in predator-prey interactions and evolutionary trends.
- Taphonomic and feeding experiment approaches that evaluate the amount and kinds of data we can reliably obtain from shells, including changes in predatory behavior, predator identity, and predation intensity.
