The Netherlands Organisation for Scientific Research (NWO) has awarded Vidi grants to Roeland Merks and Joost Batenburg. Each of them will receive the grant that allows  both reserachers to develop their own lines of research and build up their own research groups over a five-year period. The Vidi is one of three types of grants under the Innovational Research Incentives Scheme of NWO.

Roeland Merks is awarded a Vidi grant for his research project ‘Reconstructing the interactions between cells and extracellular matrix during angiogenesis'. The outgrowth  of new blood vessels is a crucial step in physiological and pathological processes including wound healing and tumor growth. A better understanding of the mechanisms of blood vessel growth will help us to steer and control blood vessel growth much more rationally in the future. In addition to research at the molecular level, this requires research into the interactions between the molecular level, the cellular and the tissue level.

An important mechanism of blood vessel growth is self-organization: blood vessel cells coordinate their movements by deforming a surrounding protein network, the so called extracellular matrix (ECM), and depositing signaling molecules into it. In his research Merks will develop new numerical techniques to simulate ECM dynamics and the interactions between cells and the ECM. The development of new computational models of the deformation of the ECM would mean a  breakthrough in this research area. The research will take place in collaboration with the VU medical centre and the Netherlands Consortium for Systems Biology (NCSB).

Joost Batenburg received a Vidi grant for his research project ‘Quantitative electron tomography by simultaneous parameter estimation and reconstruction’. Electron tomography is a mathematical technique for creating three dimensional images of microscopic objects such as biological cells and nanomaterials. The electron microscope  takes several pictures of the specimen, from varying angles. Next, these images are processed in a complex calculation yielding a three dimensional image. In practice, these computed images are often blurred because of a variety of distortions during recording; for example, the specimen may shift during recording.

In his research project Batenburg will develop computational models that are able to determine the distorting influence of these effects and by which three-dimensional images can be made much more accurate. These models will help to create sharp images of nanomaterials. Knowledge of the structure of these materials is essential in developing more efficient solar cells and computer chips.

The Vidi grant is targeted at excellent researchers who have completed their doctorates and already spent some years conducting successful post-doctoral research, thereby demonstrating the ability to generate new ideas and bring them independently to fruition. The researchers are among the best ten to twenty percent in their field. They will be given the opportunity to develop their own innovative lines of research during a period of five years.
