Dr. Hildreth obtained his BS degree in Biology from East Carolina University and his DVM from the North Carolina State University College of Veterinary Medicine. He then went on to complete a small animal rotating medicine and surgery internship at the University of Florida College of Veterinary Medicine and then a small animal surgical residency at the Ohio State University College of Veterinary Medicine. During his surgical residency, he received an extensive training in general, orthopedic, and neurologic surgery and completed a concurrent MS degree evaluating the use of parathyroid hormone-related protein (PTHrP) as an in vitro bone-forming agent with Dr. Ramiro E. Toribio.

After his surgical residency at Ohio State, he stayed to complete a PhD under the guidance of Drs. Thomas J. Rosol and Ramiro E. Toribio. His PhD focused on evaluating the roles of PTHrP in musculoskeletal development and stem cell differentiation using multiple transgenic mouse models. He also investigated the use of PTHrP as a bone-forming agent in mice using a novel bone implant system and advanced imaging modalities (radiography, microcomputed tomography (microCT), and bioluminescence and fluorescence imaging) for the potential treatment of both human and veterinary diseases (osteoporosis, fracture healing, spinal fusion, total joint arthroplasty, bone marrow transplantation). During his PhD, he was funded as a post-doctoral fellow of the National Institute of Health Center for Arthritis, Musculoskeletal, and Skin Diseases and the C. Glenn Barber Fund for Protein Research. During his PhD, he developed an intense interest in the advanced imaging of bone using microCT, particularly in response to bone-forming therapies or genetic modification. This resulted in collaborations where he performed microCT analysis for the bone biology and cancer research laboratories of Drs. Keith A. Hruska and Toshifumi Sugatani at Washington University in St. Louis and Dr. Michael C. Ostrowski of the Ohio State University College of Medicine’s Comprehensive Cancer Center.

Upon completion of his PhD in August 2014, he was hired as an associate faculty member within the Ohio State University College of Veterinary Medicine as an Instructor of Small Animal Surgical Practice. In this role, he teaches bone biology and orthopedics within the first year veterinary curriculum and general surgery and orthopedics within the third year veterinary surgery laboratories. He officially joined the Ostrowski laboratory within the Ohio State University College of Medicine’s Comprehensive Cancer Center as a Post-Doctoral Fellow in May 2015 after a long-standing collaboration. In this role, he is funded by a Pelotonia Post-Doctoral Fellowship and continues to teach within the veterinary curriculum. His current research focus is the investigation of 1) the role of osteoclasts in breast cancer bone metastasis and 2) transcription factors regulating both osteoblast and osteoclast formation.

Eason married his wife Emily in June of 2014. They live in Logan, Ohio with their young American Cocker Spaniel named Raleigh. He is an avid fan of NASCAR’s #48 Lowe’s Chevrolet driver Jimmie Johnson, the NFL’s Carolina Panthers, and Liverpool FC of the English Premier League.
