Research
My research investigates the spatial distribution and variability of trace fossils in Pleistocene and modern carbonate shoreface environments on Crooked-Acklins Platform (CAP), southeastern Bahamas. Neoichnology and modern sedimentology will be applied to the stratigraphy of CAP to link traces with depositional environments and facies in the rock record. This research will produce a conceptual ichnofacies model that will aid in understanding and predicting the distribution and effects of trace fossils on carbonate strata in ancient shoreface systems.

Thesis Title
Soil biota community’s response to C3-C4 transition in the Brady soil, Central Great Plains

Research
My research will focus on how soil biota in the Brady soil responded to climate change during the Pleistocene-Holocene boundary. The Brady soil records a change from a cooler climate to a much warmer and dryer climate. I will determine if this had an effect on the biota by using burrow size as a proxy for body size. My research will examine the distribution of taxa, any individual response to the C3-C4 transition, and an ichnotaxonomic analysis of the trace fossils. My areas of interest include paleoecology, paleoenvironments and paleontology.

Thesis Title
Sequence Stratigraphy of the Fayetteville Shale: Significance for Shale Gas Reservoirs

Research
My general area of interest is sedimentology and stratigraphy, particularly in relation to petroleum. My research focuses on the sequence stratigraphy and depositional environments of the Fayetteville Shale in the Arkoma basin. This Late Mississippian formation is a producing natural gas source in Arkansas. I hope to construct a genetic framework for use as a predictive tool for petroleum exploration. My project will incorporate outcrop, core, well log, and thin section study to determine and interpret the sedimentology, trace fossils, depositional environments, and sequence stratigraphy of the Fayetteville Shale.

Thesis Title
Ichnotaxonomy of Permo-Triassic Trace Fossils from the Beacon Supergroup, Beardmore and Shackleton Glacier areas, Antarctica

Research
My research focuses on the ichnology of the Pagoda, Mackellar, Buckley, and Fremouw formations in the Beardmore and Shackleton Glacier areas of the Transantarctic Mountains, Antarctica. Specifically, I am constructing an ichnotaxonomic database of trace fossils found in collected specimens from these localities. I am morphologically describing and naming these trace fossils and determining the tracemaking behavior represented by the organism-media interactions. Trace fossils are important because they represent hidden biodiversity, i.e., organisms that are thought to have existed based on trace fossil evidence, though their body fossils are not present. My analysis will help refine interpretations of the paleobiodiversity, paleoenvironments, paleohydrology, and paleoclimatology of Permian-Triassic strata in the Beacon Supergroup, as it represents a unique polar ecosystem.
