Research Projects

My research is focused on the development and advances in methods for interpreting taphonomic histories of vertebrate fossil material using a variety of interdisciplinary techniques. My work incorporates molecular biology techniques such as next generation DNA sequencing of bacteria and fluorescent in situ hybridization (FISH) to better understand and interpret the microbial communities involved in the early decay process of bone. My work also involves using surface characterization techniques to quantify bone weathering analyses. My research goals include applying techniques I’ve developed (weathering and microbial) to better interpret taphonomic processing of Wyoming vertebrate fossils and ultimately apply them to invertebrate fossils as well.
