Area of Interest


My research focuses mainly in the area of orthopedics. I utilize advanced imaging, in the form of micro-computed tomography, to evaluate boney tissues within a wide range of fields in various species including bone regeneration, bone & joint pathologies, bone resorption & remodeling, and craniofacial formation & defects. Ongoing studies in my lab also include utilizing contrast agents to image soft tissue structures, including articular cartilage, soft tissue structures of the equine hoof, and embryos of various species. In addition to basic science research, I also have interests in educational research, specifically utilizing computer-aided instruction & additional technologies to enhance learning by professional veterinary students in gross anatomy.
