This prestigious Fellowship honours SIAM members who have made outstanding contributions to these fields. Laurent, who is a member of the management team of CWI and a professor at Tilburg University, receives the fellowship for her contributions to discrete and polynomial optimization and revealing interactions between them.

Rubicon grants for David de Laat and Alessandro Zocca

CWI researchers David de Laat and Alessandro Zocca both received an NWO Rubicon grant. De Laat will study new techniques to compute optimal packings at MIT for one year, and Zocca will study renewables and uncertainty in future power systems at Caltech for two years. NWO granted these subsidies to 22 young, highly promising research talents to gain international research experience at foreign top institutes.

EATCS Presburger Award 2017 for Alexandra Silva

The 2017 Presburger Committee has unanimously selected Alexandra Silva, a Senior Lecturer at University College London as recipient of the prestigious 2017 EATCS Presburger Award for young scientists. She received the award for a large part of her PhD research, which she carried out in the Formal Methods research group at Centrum Wiskunde & Informatica (CWI) in Amsterdam.

Better estimation of financial risks possible with maths

Due to the recent financial crisis, the requirements imposed on banks have been made stricter. Banks must model the credit risk of the counterparties now in their portfolios, for instance. A measure for this is the credit value adjustment (CVA): the difference between the value of a portfolio without credit risk and the value if a possible bankruptcy of the counterparty is included. Qian Feng, PhD student from CWI, modelled CVAs and designed a new algorithm that can help banks estimate the risks precisely, so they can take appropriate measures if necessary.

Cécile Pierrot wins Cercle K2 Cybersecurity Trophy 2017

Cécile Pierrot from the Cryptology research group at CWI won the first Cybersecurity Trophy granted by Cercle K2. This French think tank awards prizes in 22 topics every two years. It aims at stimulating interdisciplinarity and promoting young researchers. The Cybersecurity Trophy 2017 rewarded Pierrot’s PhD thesis, which she defended at UPMC in Paris on 25 November 2016. The jury praised her for both theoretical and practical impacts of her results.

The Netherlands’ smallest supercomputer is here

A team of Dutch scientists has built a supercomputer the size of four pizza boxes. The Little Green Machine II has the computing power of 10,000 PCs and will be used by researchers in oceanography, computer science, artificial intelligence, financial modeling and astronomy. CWI researchers Joost Batenburg and Kees Oosterlee, who were part of the development team, will use the machine for computational imaging and machine learning for time series respectively. The computer is based at Leiden University (the Netherlands) and developed with help from IBM.

National Blockchain Coalition Presents Action Agenda

On 20 March, Minister of Economic Affairs Henk Kamp received the action agenda of the National Blockchain Coalition. The agenda is a joint initiative of over 20 organizations active in the logistics, energy and financial sectors, as well as governments and research institutes - Centrum Wiskunde & Informatica (CWI) being one of them. With this initiative, the Netherlands aims to be an international leader in the application of blockchain technology.

CWI researcher makes higher turnover in hotel bookings possible

With a new mathematical method, hotels can receive on average 5% more turnover in the long term when taking online reviews into account. Dirk Sierag, PhD student of CWI, analysed with historical data the behaviour of consumers booking rooms. Based on the results he designed mathematical models that can support hotels in determining optimal prices of hotel rooms. The research results can also be applied on movies, concerts, sporting events and, for example, Uber taxi rides.

ERC Advanced Grant for CWI cryptographer Ronald Cramer

CWI cryptographer Ronald Cramer has been awarded an ERC Advanced Grant of 2.5 million euro for his proposal 'Algebraic Methods for Stronger Crypto'. He leads the Cryptology Research group at Centrum Wiskunde & Informatica (CWI) in Amsterdam and is a full professor at the Mathematical Institute of Leiden University. The European Research Council awards these most prestigious personal grants to outstanding, well-established scientists with novel ideas towards high-risk, groundbreaking research that impacts both science and society at large.

CWI & Databricks: Big Data in Amsterdam

Amsterdam wants to play a leading international role in the development of data science research. In Big Data Amsterdam, Financieele Dagblad journalist Job Woudt interviews Amsterdam Data Science researchers on the functioning of the ecosystem where companies and knowledge institutions in Amsterdam collaborate in the area of ​​Big Data.

Cells’ own contractions stimulate growth orientation

During the growth of embryos cells align with forces from the surrounding tissue. These forces originate from differences in growth rates, muscle contractions or gravity. Mathematicians at the CWI research centre in Amsterdam now showed for the first time that active cell contractions can accelerate and facilitate this reorientation of cells. Their research was recently published in the leading Biophysical Journal (112).

CWI DIS group in Red Bull doc 'This is the Future'

The CWI Distributed and Interactive Systems group cooperated in a revolutionary tech project called 'Red Bull Playrooms' during ADE 2016. Red Bull has now published a documentary that gives insight to the unique elements and the work of all partners including our DIS group regarding this project. In the documentary you will see our researchers in action, together with other contributors to the project.

CWI and Google announce first collision for Industry Security Standard SHA-1

'Industry deprecation proved to be too slow' Today, Thursday 23 February 2017, researchers at the Dutch research institute CWI and Google jointly announce that they have broken the SHA-1 internet security standard in practice. This industry standard is used for digital signatures and file integrity verification, which secure credit card transactions, electronic documents, GIT open-source software repositories and software distribution.

CWI develops strategies for compression and transmission of reconstructed 3D data

Internet is used for communication via video conferencing, voice calls, chatting, photo sharing, online gaming and virtual reality. These technologies are changing our daily lives and the way we interact with each other. Highly realistic reconstructed 3D representations that combine real and synthetic contents in a virtual world will be part of this online interaction more and more.
