Prof. Dionysios Papachristou is a physician and specialized pathologist. He obtained his MD and PhD at the Medical School of the University of Patras,. He had postdoctoral training on bone biology and pathology at the Department of Pathology, University of Pittsburgh, School of Medicine, Pittsburgh, PA, USA (2004-2006), where he also served as full time faculty member (2007-2009). He was a visiting clinician at the Department of Pathology at the Mayo Clinic, Rochester, MN, USA at the Division of Bone Pathology (2006). Currently, Dr. Papachristou is Associate Professor of Anatomy-Histology-Embryology, University of Patras, School of Medicine and Assistant Professor (Adj.) of Pathology at the University of Pittsburgh.

His research interests focus on: 1) the pathogenesis of bone and soft tissue tumors, 2) the pathobiology of metabolic bone diseases and other related conditions, 3) the investigation of the mechanisms of bone metastases. 4) the role of mechanotransduction in bone metabolism 5) Molecular mechanisms of fracture healing
