Broad Research Areas
The Department of Geography and Geology actively encourages and supports undergraduate and graduate student research. Our students participate in research projects covering many aspects of the geosciences. In the past, students have been involved in projects such as investigating hydrothermal venting at mid-ocean ridges, monitoring groundwater wells, studying ancient fossils of the southeastern coastal plain, reconstructing sea levels, mapping patterns of change in African savannas, and multiple other activities. Being a highly interdisciplinary department, we encourage interested undergraduate and graduate students to contact faculty members working in their research area of interest. Below, we list broad research areas faculty members in the department are involved in, followed by more specific research laboratories in our department. We welcome students with diverse interests: chances are, you will find your passion with us!
Specialized Research Laboratories
The Basin Analysis Research Laboratory (BARL), led by Dr. Todd LaMaskin, is an applied learning research lab that uses a wide array of tools to address problems in sedimentation, stratigraphy, tectonics, and geologic time in a broad theme of understanding the evolution of sedimentary basins over time. Current research in the LaMaskin lab falls into two broad categories: (1) Using sedimentary provenance to understand the evolution of plate margins and continental sediment dispersal systems, and (2) Using stable isotope stratigraphy to establish a chronostratigraphic signature for the Late Triassic, Carnian-Norian Boundary interval. The lab maintains its primary workspace in the group-use Advanced Microscopy Laboratory, a 400 sq. ft facility housed in DeLoach Hall (RM 215). The Advanced Microscopy Laboratory is houses research-grade petrographic microscopes (Olympus BX-60 and Leica M165C with HD camera) and research-grade stereo microscopes (Leica DM2700P with attachable Leica DFC 450 camera and Leica DMEP). The lab also hosts a fume hood used for sodium polytungstate heavy mineral separation, a magnetic separator, light table, a sink and cabinets for storage. BARL researchers also routinely utilize workspace in the Clean Laboratory, the Geologic Materials Laboratory, Isotope Ratio Mass Spectrometer (IRMS) Laboratory, and Spatial Analysis Laboratory.
The Crustal Dynamics and Geophysics Laboratory, led by Dr. Scott Nooner, makes available the following equipment:
Mac workstations and PC laptops with Matlab, COMSOL finite element software, ArcGIS, Adobe Illustrator, and LabView, Broadband Seismometer, pressure gauges (for seafloor geodesy), Solinst water level recorders and air pressure recorders, Deadweight tester (for pressure gauge calibration), Ground Penetrating Radar, GPS antennas and receivers, Starfish towed sidescan sonar and a Soldering workstation.

The director of the Invertebrate Paleontology Lab, Dr. Patricia Kelley, in collaboration with Thor Hansen (Western Washington University) has compiled a database on predation by shell-drilling naticid gastropods in the Gulf and Atlantic Coastal Plain; collections now include >150,000 mollusc specimens of Cretaceous through Pleistocene age.Recent and current work in collaboration with graduate students includes: the ecological response of the Iceland molluscan fauna to the invasion of predatory gastropods during the Pliocene; taphonomy of an ophiuroid mass mortality bed in Mexico; geographic variation in drilling predation in Brazil and Argentina; relationship between drilling predation and prey diversity in the US Coastal Plain and Europe; conditions under which cannibalism by drilling predators occurs; metabolism and extinction susceptibility in Plio-Pleistocene bivalves; escalation, coevolution, and drilling predation on bivalves and gastropods; factors affecting durophagous predation in ammonites, bivalves, and gastropods; live-dead comparisons of molluscan assemblages as tools in conservation paleobiology; life span bias in the fossil record. Kelley also directed (with Greg Dietl, Paleontological Research Institution) a Research Experiences for Undergraduates in Biodiversity Conservation program investigating paleoecological changes in the Plio-Pleistocene of the Carolinas (based on collections amounting to >75,000 mollusc specimens) as an analog for the modern biodiversity crisis.

The second is a Thermo Finnigan Gasbench II system that can be used for the isotope analysis of carbonates (C and O), headspace (C, N, O, H), dissolved inorganic carbon (C, O), and water (O, H). The third is a Thermo 1310 gas chromatograph and interface for C,H, and N compound-specific isotopic analyses. The fourth is an Aurora 1030 TIC/TOC analyzer that can be used to analyze the stable carbon isotope composition of dissolved inorganic and organic carbon. The Isotope Mass Spectrometer Lab also houses an Thermo 1310 GC-MS/FID system for the identification and quantification of organic compounds, two high-precision microbalances, and a micromill.
