Jeremiah Easley, D.V.M.

Director, GLP Test Facility Manager

 Dr. Easley serves as the director of the Preclinical Surgical Research Laboratory located within theTranslational Medicine Institute at Colorado State University. He is a Diplomate of the American Collegeof 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-relatedmedical 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 morecomprehensively mimic the human orthopedic conditions. Dr. Easley acquired his Doctor of VeterinaryMedicine from the Virginia-Maryland Regional College of Veterinary Medicine in Blacksburg, VA. He thenwent on to pursue large animal surgery by completing an internship at the Equine Medical Center ofOcala in Ocala, FL followed by a three-year large animal surgical residency at the University of Floridain Gainesville, FL.

Drew W. Koch, D.V.M., Ph.D.

Surgeon

Drew joined PSRL in 2023 and is a veterinary surgeon, principal investigator, and an Assistant Professor. He completed his DVM and large animal surgery residency at Colorado State University and his PhD in Comparative Biomedical Sciences at North Carolina State University. He is a Diplomate of the American College of Veterinary Surgeons. His research focuses on elucidating the role of stromal cell senescence in the progression and treatment of musculoskeletal and orthopedic injuries, as well as advancing and refining large animal models to study these conditions.

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.

Katie Bisazza, Ph.D.

Preclinical Surgical Scientist

Katie has been a part of the Preclinical Surgical Research Laboratory team at Colorado State University since 2016. After receiving her PhD from Colorado State University in 2024 in Clinical Sciences, Dr. Bisazza has taken on the role of lead preclinical study director in the large animal division of PSRL. In her role, she oversees a multitude of both GLP and non-GLP preclinical studies using small ruminant models (i.e., sheep and goat) for industry and academic partners. Her previous research focused on characterizing the progression of bone loss in an ovine model of osteoporosis using advanced imaging and proteomic techniques.

Andrés Bonilla, D.V.M., Ph.D.

Preclinical Surgeon Scientist

Andrés has been a member of the Preclinical Surgical Research Laboratory (PSRL) at Colorado State University since 2019. He came from Colombia as a Fulbright Scholar and completed his PhD in Clinical Sciences at Colorado State University in 2024. Since joining PSRL, he has focused his work on advancing translational research in spine surgery, with a strong emphasis on computer-assisted surgery, surgical navigation, and the development of large animal models for musculoskeletal disease.

His research interests center on the integration of image-guided technologies and navigation systems to improve precision and reproducibility in preclinical surgical models, supporting the translation of innovative techniques into clinical practice. In addition to his research activities, he is actively involved in education and mentorship, guiding veterinary students and surgical residents in preclinical methods, experimental design, and the application of computer-assisted surgical technologies.
