My research focuses on evolutionary and ontogenetic studies of normal and pathologic bone growth in modern and fossil vertebrates, principally archosaurs (including crocodylians, dinosaurs, and birds).  I deal with skeletal change both at the gross level and through histological studies of bone microstructure.  I am also interested in vertebrate taphonomy and paleoclimate studies.

Current and ongoing projects (including supervised undergraduate research) include:

• Paleopathology of archosaurs and mammals
• Implications of changes in vertebrate bone surface textures for assessing relative ontogenetic age
• Taphonomic indicators of climate change during the Eocene-Oligocene Transition in the White River Group

Research projects by former M.S. students include:

• Histology and geochemistry of polar dinosaur bone tissue
• Histology, mineralogy, and geochemistry of normal vs. pathological bone tissue in dinosaurs and modern birds
• Cladistic analysis of craniofacial ontogeny in ceratopsian dinosaurs
