René van Donkelaar obtained his PhD degree in 1999 at the Maastricht University, after which he moved to the Biomedical Engineering Department of the Eindhoven University of Technology in The Netherlands, where he is currently appointed associate professor in cartilage mechanics. Using fundamental insights on the mechanical behavior of cartilage, he established a well-recognized computational model of cartilage mechanics. The main asset of this model is that it directly links biochemical contents (distributions of proteoglycans and collagen) and structural features (collagen fiber orientation), to mechanical properties. This fundamental work on cartilage mechanics has been applied to develop loading protocols for cartilage tissue engineering, and understanding tissue adaptation and degeneration. Present focus is on adopting the insights on how adverse mechanical loading leads to progression of osteoarthritis, to develop diagnostic tools and superior methods for clinical intervention for treatment of osteoarthritis.
