Janne-Mieke Meijer: Unravelling the origin of disorder during self-assembly

Nowadays, the spontaneous self-assembly of nano- and micro-particles is used for the development of many new and innovative materials. Unfortunately, for building blocks with specific shapes and interactions, we lack critical understanding about the disorder that emerges during assembly. Added to that, control is inadequate, and this limits the fabrication and exploitation of these new materials.

The goal of of the project of Janne-Mieke Meijer (department of Applied Physics and Science Education) is to unravel on the smallest scale how during self-assembly processes the particle properties lead to disorder. This insight will be important for nano- and biomaterials, and Meijer plans to create new materials as part of the project.

鈥淚t is an honor to receive this funding amid so many talented peers in the field, and I鈥檓 excited to get started with my new research team,鈥� says Meijer.

Meijer will use the funding to perform advanced microscopy studies on how and when disorder emerges during the self-assemble of tiny particles. 鈥淲e need an understanding of these processes as many future materials will rely on this type of fabrication process,鈥� notes Meijer. 鈥淎nd that鈥檚 good news for materials for applications in healthcare and energy storage.鈥�  

Wouter Meulemans: Algorithms for effective information visualization

Data is often visualized, supporting analysts in understanding the data and make informed decisions. To achieve this, reliable and accurate algorithms are needed to create visualizations in an automatic fashion. These algorithms should place all visual elements in an optimal manner so that the visualization is as legible as possible for the end user.  

However, visual complexity is currently not properly accounted for in visualization algorithms, and thus the visualizations they create. Instead, simple indicators are used that do not relate well with visual complexity, while inadequate complexity hinders interpretation. 

For his Vidi project, Wouter Meulemans  (department of Mathematics and Computer Science) will integrate visual complexity with algorithms for visualization, such that the complexity can be controlled explicitly, and facilitate a structural trade-off between different quality aspects. This will allow for the portrayal of the underlying data, with its trends and patterns, in the best possible way. 

鈥淚t鈥檚 an amazing opportunity to start my research line with a PhD student and a postdoc,鈥� says an enthusiastic Meulemans. 鈥淲ith this team, we aim to the plan is to develop ways to elevate information-visualization algorithms to the next level. I can鈥檛 wait to get started!鈥� 

The impact of Meulemans鈥� research could be multifold: 鈥淎lgorithms explicitly controlling visual complexity will reliably create high-quality visualizations of data that allow users to better understand complex behavior and phenomena in nature, science, society, and business.鈥� 

Tugce Martagan: Increasing patient access to lifesaving medicines

For some patients, the price of many drugs exceeds 100,000 euros per year. As a result, patients can struggle to access these lifesaving, yet expensive medicines. Added to that, insurance companies are struggling to cover the costs of the medicines.

In her project, Tugce Martagan (department of Industrial Engineering and Innovation Sciences) will examine pharmaceutical drug production from the perspectives of governments, industry, insurers, and pharmacists. She seeks to develop new incentives and public policies to increase patient access to affordable medicines. In addition, optimization models will be developed to achieve cost-effective and safe production of drugs in pharmacies.

Martagan: 鈥淭his funding provides me with the opportunity to explore the applications of operations research methodologies in personalized medicine and healthcare policymaking. I鈥檝e always been passionate about healthcare, and I鈥檓 grateful to NWO for providing the support and funding to help me follow my passion.鈥�

For the project, Martagan will seek to recruit two PhD researchers and work with them together with an interdisciplinary team of end-users consisting of government agencies, industry, insurers, pharmacists, and patient advocates. 鈥淚 look forward to collaborating and co-creating with my colleagues from the Dutch life sciences and healthcare community!鈥� adds Martagan.

Ruud van Sloun: Neuroscience-inspired ultrasound imaging

Ultrasound, which involves the use of acoustic waves to image tissue, is the most widely-accessible and sustainable medical imaging technology. Magnetic Resonance Imaging (MRI) is diagnostically superior, but expensive in comparison.

For his Vidi funded project, Ruud van Sloun (department of Electrical Engineering) aims to push ultrasound quality towards that of MRI through the development of a unique neuroscience-inspired approach to imaging.

鈥淯ltrasound systems should become intelligent active perceivers, just like our brain鈥�, says van Sloun. 鈥淭hey should be systems that do not merely passively interpret incoming data but instead actively influence their observations in order to maximize crucial diagnostic information.鈥�

Van Sloun is delighted to receive the NWO Vidi grant: 鈥淚t gives me the freedom and momentum to pursue the research that I really want to do鈥�.

The biggest challenge that van Sloun and the team of researchers who will work on the project relates to the design of autonomous ultrasound systems. 鈥溾�橦ow can we design autonomous ultrasound systems that actively seek to maximise diagnostic information for every patient?鈥�, that is a key question that I鈥檓 seeking to answer in this project,鈥� adds van Sloun.

About the NWO Vidi grants

Vidi fellowships are aimed at experienced researchers who have carried out succesful research for a number of years after their PhDs. Together with the Veni and Vici scholarships, Vidi is part of the NWO Talent Programme. With this program the  wants to stimulate curiosity-driven and innovative research.

A total of 551 researchers submitted an application for a Vidi grant this year, of which 97 were awarded grants. That amounts to an award rate of 18%. The gender ratio of awarded grants is 54 men and 43 women, with the award rate among both men and women being 18%.
