Research Overview

Stable isotope geochemistry of biogenic apatite and of carbonate minerals with interpretation of ancient climatic conditions; vertebrate paleontology and biostratigraphy; annual-scale studies of ancient climate and dietary sources of fossil vertebrates using stable isotopes of tooth and bone apatite; annual-scale studies of ancient climate using stable isotopes of fossil mollusk shell aragonite; uranium hydrogeochemistry and its relation to uranium ore deposition and fossil preservation; vertebrate taphonomy; isotopes in biostratigraphy and global correlation; application of GIS to problems in paleontology; the conflict between evolution and creationism (including Intelligent Design).

Research Opportunities for Graduate Students

I am currently unable to take on graduate students. However, I do regularly take on undergraduates for senior thesis or independent study projects, working on some aspect of the research described above. Occasionally, I will also take an undergraduate out to Wyoming with me as a field assistant. For field assistants, I typically select students that have completed my Principles of Paleontology course.

Furthermore, I regularly take on one or two high school students for summer internships to assist me in completing the laboratory work needed for my research. It is an opportunity for college-bound students to gain some practical science and laboratory experience while learning and working on a specific scientific problem.
