He has over twenty years of experience in the areas of Metallurgical and Materials Engineering research. His specialties include ceramic and inter-metallic biomaterials for bone engineering and the analysis of tissues as materials. He is on the forefront of metallurgical and bio-mechanics research, and as a result has undertaken the study of dozens of issues in the field of biomechanics. His research experience is impressive in its range and volume. He has published over 60 articles and book chapters in the course of his career, which he began as a Mass Properties Engineer in the private sector before transitioning to academia and research. He has since performed research at the University of Colorado and Colorado State University, and is now an Assistant Clinical Professor of Orthopedics at the UC Denver School of Medicine and an Assistant Professor of Engineering at the Colorado School of Mines.
