Faculty Research

The program hosts several active areas of faculty research interests, and undergraduate students are an absolute integral component.  We are always looking for energetic, motivated, and driven students to be a part of vibrant team of researchers.  In addition, many of the classes that students take in Geology will also experience the research atmosphere at current topics and trends are discussed and experimented with.  Below are brief descriptions of focused research areas as well as the contributing faculty members.

Tectonics, thermochronology, geochronology, tectonic geomorphology and structures

Dr. Nahid Gani's research investigates landscape evolution through geologic time from the complex interplay among tectonics, erosion, surface and subsurface processes, climate and environmental impacts, to address grand challenges of  earth-systems feedback problem. The research tools she uses include low-temperature thermochronology from igneous, metamorphic and sedimentary rocks, geochronology of igneous (mostly granites and volcanics) rocks, quantitative geomorphology, field and lab-based structural modeling, thin section petrography and electron microscopic analysis, and GIS and remote sensing. Her study area includes geologically diverse places like the Ethiopian Plateau in the East African Rifts, which is the world’s longest continental rift, and the cradle for human evolution, the Nepalese Himalaya (one of the world’s highest mountain ranges), the Bengal Basin, various regions of the USA, and the Red Planet Mars.  Motivated undergraduate and graduate students interested to learn more about Dr. Gani's research, browse her homepage, and contact Dr. Nahid Gani for more information.


Sedimentary geology, paleoclimate, stable isotope geochemistry and human evolution

Dr. Roynan Gani's research primarily focuses on (1) sedimentary Geology, which includes basin analysis; sequence & seismic stratigraphy; hydrocarbon reservoir analog; unconventional resources (tight-gas, oil shale/sand); subsurface mapping by integrating well logs, 2D/3D seismic, and cores; ground penetrating radar (GPR); from source to sink; facies analysis and depositional environments; ichnology and paleoecology; paleoclimatology. (2) human evolution – Paleoclimate and hominin evolution of East Africa, and (3) paleoclimate and paleovegetation – multi-system stable isotopic analysis (δ18O, δ13C, and δD from paleosol carbonates and compound-specific analysis of organic materials) of the Cenozoic strata of Nepal Himalaya.  See the homepage of Dr. Royhan Gani for more information.


Energy and groundwater resources

My current research focuses on the integration of outcrop and subsurface databases in Kentucky and adjacent areas in Mississippian and Pennsylvanian rocks. I have a special interest in energy and groundwater resources straddling the sub-Pennsylvanian surface or what is formally known as the Kaskaskia-Absaroka Sequence Boundary. The energy resources research of late has been mostly in unconventional oil, asphalt rock or tar sands, particularly those in Edmonson County and nearby areas of Kentucky. This work involves both traditional sedimentologic and stratigraphic methods in the field and subsurface but also petrographic characterization of these rocks, petrophysics, and to a lesser extent analysis of fluids. This research engages undergraduate and graduate students and utilizes standard transmitted and reflective light microscopy, SEM, and we are also beginning to incorporate Raman microscopy and XRD analyses in our studies.  Contact Dr. Mike May for more information.


Carbonate sedimentology and paleontology

Dr. Fred Siewers is a sedimentary geologist with expertise in carbonate sedimentology, geochemistry and invertebrate paleontology. He received his Ph.D. in 1995 from the University of Illinois, where he worked on the origin and stratigraphic significance of discontinuity surfaces (hardgrounds and paleokarst surfaces) in Middle Ordovician limestones. He has extensive experience in field geology as well as with a variety of laboratory techniques, including sedimentary petrography, cathodoluminscence microscopy, scanning electron microscopy, and geochemical microanalysis. Current projects are focused on the petrology and origin of Middle Pennsylvanian coal-ball concretions and the use of ostracodes for paleoenvironmental reconstruction of Bahamian lakes. He teaches courses in Earth History, Geological Field Techniques, Sedimentology and Stratigraphy, Paleontology and Professional Preparation, and he advises undergraduate and graduate students in a variety of independent research projects. Recently, he has turned his research and teaching focus to clean energy, sustainability and climate change issues and has projects underway with the Illinois State Geological Survey focused on geological carbon sequestration.  Contact Dr. Fred Siewers for more information.


Petrogenetic history of volcanic rocks in the Chilean Andes and Mojave Desert

Dr. Andrew Wulff's recent research interests include the petrogenetic history of volcanic rocks in the Chilean Andes and Mojave Desert, the health effects of residential radon and airborne particulate quartz dust, and connections to anthropology/archeology such as the sourcing of chert artifacts using trace element signatures, and the modeling paleoenvironments associated with early hominid finds in Java. These research interests involve quantitative analysis of a wide variety of geological materials using XRF, XRD, ICP-MS, SEM and electron microprobe, and he is pleased to have both undergraduate and graduate students as colleagues in all aspects of these investigations. Dr. Wulff also has a strong interest in developing innovative teaching strategies for all levels and is active in contributing to the earth science curricula in the local school district. Andrew is the 2013 winner of the WKU and Ogden Faculty Award for Outstanding Teaching. He is active in training and leading workshops for pre- and in-service earth science teachers. Contact Dr. Andrew Wulff for more information.


Advancement of geoscience education

Dr. Margaret Crowder is a geologist focused on geoscience education and the advancement of women in areas of science, technology, engineering, and mathematics (STEM). She has an MST in geology from the University of Florida and an EdD in educational leadership from Western Kentucky University. Her specific research interests from a pedagogical perspective are in the classroom incorporation of student-centered, problem-based learning for enhanced student engagement and understanding. She is currently working to develop more hands-on, inquiry focused laboratory experiences for introductory geology students. From an educational leadership perspective, Dr. Crowder is also interested in gendered organizations and the effects that gendering has on women in STEM disciplines and on women in the wider world of academia. In her dissertation The University as a Gendered Organization: Effects on Management Type, Climate, and Job Satisfaction, she studied faculty job satisfaction and perceptions of organizational management type and climate, particularly focusing on the differences in these areas between genders and among college disciplines. Contact Dr. Margaret Crowder for more information.
