Career
In the past he also worked as a visiting scientist at the University of California, Los Angeles bone research laboratory. His work has focused on the research and development of bioceramics that resemble the composition of bone. He has developed two types of bioceramic, namely bulk ceramics (dense, porous, large and small) for mechanically unloaded bone fillers, and coatings for improving the bone bonding of strong, but less biocompatible, metallic orthopedic and dental implants.
His group also studied the incorporation of drugs and growth factors such as Bone Morphogenetic Proteins (BMP) into such ceramics and coatings, as well as the use of calciumphosphate particles for plastic surgery, id est (that is) filling and augmenting soft and hard tissues for cosmetic reasons (together with The Communications Advertising and Marketing Implants BV(Now called Cam Bioceramics)).
His research products are being marketed by The Communications Advertising and Marketing Implants (now Cam Bioceramics), IsoTis and Stryker (United States of America). Prior to his present appointment he worked at Vrije Universiteit (VU), Amsterdam (until 1988) and Leiden University (until 2001), at both places as head of the department of biomaterials.
He has published more than 350 articles and he is the co-inventor of about 10 patents.
