About:
Ryan is an associate professor of anthropology and information sciences and technology as well as co-director of the Center for Quantitative X-Ray Imaging at Penn State. He earned a B.A. in anthropology from the University of New Orleans and an M.A. and Ph.D. in anthropology from the University of Texas at Austin. Ryan is primarily interested in primate and human evolutionary morphology, skeletal biology, and bone biomechanics. His research makes use of advanced computational techniques such as high-resolution microcomputed tomography imaging and three-dimensional quantification to understand bone function and biomechanics. Ryan’s research seeks to answer questions related to normal bone development, the responsiveness of bone to mechanical loading, and the relationship between specific human activity patterns and bone structure. Ryan is also interested in developing techniques for effective 3D imaging and scientific visualization.
Research Interests:
• Bone biomechanics
• High-resolution computed tomography
• Primate and human evolutionary morphology
• Primate locomotion
• Skeletal biology
• Three-dimensional scientific visualization
Teaching:
• Primate and human evolutionary morphology, skeletal biology, and bone biomechanics
