My research focuses on evolutionary and ontogenetic studies of 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.

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

• Comparison of thin-section and MicroCT analyses as sources of bone microstructure data
• Implications of changes in bone surface textures for assessing relative ontogenetic age
• Paleopathology

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
