I am a sedimentary geologist and taphonomist most interested in studying terrestrial and marginal
marine depositional systems, especially those with abundant fossils. My current research focuses on
understanding how fossilization of vertebrate remains transpires in different depositional settings (lakes vs. rivers vs. soils).
To this end, my students and I have been exploring the diagenesis of vertebrate fossils from the Cretaceous of Montana
(specifically the Two Medicine and Judith River Formations) and Madagascar using a variety of analytical techniques,
including SEM-EDS, LA-ICP-MS, and standard petrographic microscopy. My other on-going research interest is the
reconstruction of terrestrial ecosystems using sedimentological
and taphonomic lines of evidence. This work has
taken me to the Cretaceous foreland basin of Montana, the Triassic Ischigualasto Basin of Argentina, the
Triassic-Jurassic Karoo-equivalent rocks of southern Zimbabwe, and the Mahajanga Basin of Madagascar.
I teach a selection of courses at Macalester College that relate to my research interests, including: (1) History
and Evolution of Earth (GEOL 165), (2) Paleobiology (GEOL 300), and (3) Sedimentology and Stratigraphy
(GEOL 265). A significant part of my time is spent mentoring student research, and I work with students
both in the laboratory and in the field. For more information on our department curriculum and student research
opportunities, please see the links above.
