Jeremiah Easley

Jeremiah Easley, D.V.M.

Director

Dr. Easley serves as the director of the Preclinical Surgical Research Laboratory located within the Translational Medicine Institute at Colorado State University. He is a Diplomate of the American College of Veterinary Surgeons with over 10 years of experience working with industry and institutional partners. His area of expertise focuses on the evaluation of orthopedic, spine, and sports medicine-related medical devices, and orthobiologics, utilizing both large and small animal translational models. Additionally, Dr. Easley’s research focus is aimed at developing new large animal models that more comprehensively mimic the human orthopedic conditions. Dr. Easley acquired his Doctor of Veterinary Medicine from the Virginia-Maryland Regional College of Veterinary Medicine in Blacksburg, VA. He then went on to pursue large animal surgery by completing an internship at the Equine Medical Center of Ocala in Ocala, FL followed by a three-year large animal surgical residency at the University of Florida in Gainesville, FL.

Katie Sikes

Katie Sikes, Ph.D.

Study Director, Rodent and Rabbit Division Manager

Katie Sikes received her Bachelor of Science in biomedical engineering from the Rose-Hulman Institute of Technology in 2011 and her Doctor of Philosophy in bioengineering from the University of Illinois at Chicago in 2016 while completing her research at Rush University Medical Center. She completed her post-doctoral fellowship with Dr. Dave Frisbie at the Orthopaedic Research Center, where she was awarded a fellowship grant by the Orthopaedic Research and Education Foundation for her work studying metabolic injury mechanisms in a mouse model of tendinopathy. In 2019, Sikes became a research scientist with the Preclinical Surgical Research Laboratory to spearhead the development of the Rodent and Rabbit Division.

Ross Palmer

Ross Palmer, D.V.M.

Surgeon

Dr. Palmer’s career has included both private specialty practice ownership and academic roles as a clinician-scientist. He serves as principal investigator on selected orthopedic projects within the Preclinical Surgical Research Laboratory and has particular expertise in large animal models for bone healing and ACL repair.

Palmer holds a secondary appointment in the School of Biomedical Engineering, and has served multiple roles on the board of directors for the Veterinary Orthopedic Society, most recently as president. He was the recipient of the Educator of the Year award in 2020 by the Veterinary Meeting & Expo, the world’s largest veterinary educational conference. He is currently the associate director of education for the CSU Translational Medicine Institute.

Brad Nelson

Brad Nelson, D.V.M., Ph.D.

Surgeon

Dr. Nelson’s research interests are in orthopedic disease characterization and the investigation of novel treatments using translational large animal models. These interests are focused on the use of quantitative MRI and CT imaging for early joint disease detection and monitoring of healing in articular cartilage, though extend to all orthopedic tissues.

Holly Stewart

Holly Stewart, V.M.D., Ph.D.

Surgeon, Study Director

Dr. Stewart received her V.M.D. from the University of Pennsylvania, followed by an internship at Pioneer Equine Hospital in Oakdale, California. Following her internship, she completed a residency at the University of Pennsylvania’s New Bolton Center and became board certified in large animal surgery. After her residency, Holly earned a Ph.D. in clinical orthopedics at Colorado State University. Her research is focused on evaluation of bone edema/bone marrow lesions, including the development of translational experimental models for bone edema, and optimization of volumetric imaging for detection of fluid within bone.

Lindsey Burton

Lindsey Burton, Ph.D.

Study Coordinator

After receiving a B.S. in environmental health and an M.S. in toxicology from Colorado State University, Burton worked as an environmental health specialist prior to returning to CSU to complete a Ph.D. in toxicology. Burton’s Ph.D. focused on iron accumulation and knee osteoarthritis, a topic that she continues to investigate with Dr. Kelly Santangelo, an associate professor in the Department of Microbiology, Immunology, and Pathology.

As a postdoctoral fellow with the Preclinical Surgical Research Laboratory, Burton investigates molecular patterns contributing to the pathogenesis of both primary and post-traumatic knee osteoarthritis, interactions between knee joint tissues, and articular cartilage biology.
