Areas of Interest

Paleontology

Research

My research interests include paleontologic principles and methods, quantitative methods in paleontology, and paleoecology. I also publish on the taxonomy of Paleozoic brachiopods. Current research projects involve:

Quantitative biostratigraphy
Facies models based on facies transition counts
New approaches to community paleoecology
Investigation of the evolution and distribution in time and space of Silurian and Lower Devonian Spiriferid brachiopods
Analysis of fining/coarsening upward sequences of strata
