Graduate Studies

Our graduate students in stratigraphy and stratigraphic paleontology study a range of problems mostly centered on some aspect of sequence stratigraphy and its application to paleontologic problems. Some test particular claims of the sequence stratigraphic paradigm, such as the correlatability and synchroneity of surfaces. Others apply sequence principles to particular field problems. Recent work emphasizes the relationships between sequence stratigraphic architecture and many aspects of paleontology, including morphometrics, biostratigraphy, and paleoecology. Students with interests in combining paleontology and stratigraphy are highly encouraged to apply. The Stratigraphy Lab emphasizes field work, the pursuit of outside funding for their research, and the publication of research.

My advising style is hands-on: I generally meet with each of my students for half an hour to one hour every week, and we have an informal lab meeting every week. I have an open-door policy and encourage students to stop by when they have questions. We also try to have a Stratigraphy Lab field trip at least once a year, plus movie nights every semester. We strive to keep a positive lab environment, and diversity is important.
