RESEARCH INTERESTS


I am a field-based geologist interested in reading Earth history from the sedimentary record. Earth-system interactions have galvanized my interests in paleoclimate, as Earth’s climate is the nexus of the Earth system. The theme that permeates much of my research is the late Paleozoic world of 300 million years ago. This interval archives the global mountain building that culminated in the assembly of the Pangaean supercontinent, and preserves the record of Earth’s last great “icehouse” and collapse of that icehouse. If we wish to learn about glacial climate systems and associated glacial-interglacial shifts like those of today, glacially driven sea-level changes, major tectonic disruption, the effects of atmospheric dust, and biotic responses to these varied forcings, no time beats the late Paleozoic.




TEACHING AND ADVISING


Teaching and Advising Philosophy

Science is useless without communication of results. Furthermore, communication skills remain a hurdle for most students. Hence, I strongly encourage all my advisees to present their work at national meetings and ultimately publish results in refereed journals. Preparation of a publishable manuscript is extremely demanding, but personally rewarding, an ideal learning experience, and ultimately incumbent upon us as scientists and funding recipients.

I emphasize study of real rock data in all class and research projects, as the field is the ideal forum for geological education, and the ultimate source of geological truth. For my advisees, this means a strong field or core (if subsurface) component to their research. Many students will progress to employment that requires geologic interpretation based on remotely sensed images or models of rock data; accordingly, students must gain experience with real rock data.


Special Note to Prospective Graduate Students

I am particularly interested in students willing to consider fieldwork as well as laboratory analyses. To date, my field sites have included the western U.S. and Canada, Japan, France, and Antarctica. If you are interested in sedimentary geology studies aimed at addressing questions about “deep-time” paleoclimate or allied subdisciplines, please contact me. Future projects will address climatic, and tectonic-climatic interactions in tropical Pangaea, atmospheric dust as a climatic archive and agent in Pangaea, climatic controls on chemical and physical weathering, and origins of Martian dust. I have high expectations: my students work hard, and have a passion for the science and a willingness to do the work required to publish research results in peer-reviewed journals. My goal is to train students to think critically and broadly in our discipline, and contribute to the field.


Courses Taught

I regularly teach upper-division undergraduate and graduate-level courses in Earth’s Past Climate (co-taught with Meteorology professor Dr. Susan Postawko), Carbonates & Sequence Stratigraphy, and Depositional Systems & Stratigraphy. The latter two courses involve a substantial fieldtrip to world-class outcrops in the Sacramento and Guadalupe Mountains (pictured below) of New Mexico and West Texas. I also teach Introductory Geology, an Honors course in Earth-Sustainability topics, and lead seminars on various “soft-rock” topics.
