The Research Group Evolutionary Developmental Biology at Ghent University focuses on development, plasticity, and remodeling of skeletal tissues; in particular bone, cartilage and teeth in teleost fish. Processes are analyzed in a comparative developmental and evolutionary context.  We study mechanisms underlying continuous tooth replacement, we do biomedical research on various skeletal tissues and we study how to prevent vertebral column malformations in famed fish.  We organize the intentional conference “Interdisciplinary Approaches in Fish Skeletal Biology” (

Two PhD projects (ESR11 and ESR12) address questions about dietary phosphorus requirements and how dietary phosphorus alters bone and tooth development.  Farmed Atlantic salmon is studied to prevent vertebral column malformations.  Zebrafish is studied as a model for osteomalacia in humans and related skeletal diseases.
