Research Interest

We use the principles of functional and evolutionary morphology to the study of complex structural systems of model organisms to answer causal, “how?” questions and evolutionary, “why?” questions. Specific hypotheses can be tested within clinical or evolutionary contexts through experimental means or through natural experiments that compare carefully selected vertebrates. A focus in my lab is to understand the causal relationship between body postures/movements and tissue degeneration using force analysis methods on 3D and 4D models generated from CT data. Current projects are investigating the use of biotensegrity as a conceptual framework to (1) analyze the relationship between whole body postures/movements of the horse and the resulting degeneration of the skeletomusculofascial system and (2) analyze the functional, symbiotic relationship between horse and rider.

Teaching Interest

I am a broadly and classically trained comparative morphologist, and my teaching expertise includes gross anatomy and gross- and micro-dissection, histology, developmental biology, biomechanical analysis, and visualization. The morphological sciences provide the foundation on which veterinarians stand as they treat animals. Integrating and establishing conceptual connections between gross anatomy, histology, embryology, and physiology provides an understanding of the “normal” animal that is necessary to treat the unwell one. I am invested in not only helping students build a strong foundation of anatomical knowledge, but also in developing the skills (e.g., communication, collaboration, observation, time management, development of personal study strategies) necessary to do well as they proceed in their education and training.

Clinical interest

In addition to my clinically-based research, I enjoy collaborating with clinicians by providing expertise in anatomy and visualization. I have used (or adapted for my use) several techniques, including biometrics and statistics, micro-dissection,and static force analyses for functional and clinical applications. I also use various graphics, imaging and animation computer programs for the presentation, computation, and analysis of research in 2D, 3D, and 4D.
