Research

My research focuses on later phases of human evolution with an emphasis on the distinctive craniofacial morphologies of Neandertals and modern humans.  My current projects focus extensively on linking evolutionary changes in upper respiratory tract anatomy to physiological demands for respiratory air-conditioning (heat and moisture transfer) in different climates.  In particular, my laboratory specializes in the 3D modeling and geometric morphometric analysis of upper respiratory tract anatomy using high-resolution medical imaging modalities (e.g., CT, μCT, MRI).  I have also developed a strong collaborative relationship with Dr. Brian Dennis, director of the NSF/DOE/DARPA-funded Computational Fluid Dynamics Laboratory at the University of Texas at Arlington.  By merging our two areas of expertise, we have successfully established protocols for quantitatively assessing functional relationships between upper respiratory anatomy and airway physiology under controlled environmental conditions.

Current Projects

• Climate and ecogeographic variation in human nasal anatomy

• Evolutionary “mismatches” and modern respiratory health (e.g., asthma, sinusitis, sleep apnea).

• Developmental integration of nasal/sinus morphology and surrounding facial anatomy

• Climatic and energetic influences on Neandertal facial morphology and evolution
