Frank den Hollander was one of the leading researchers in mathematics taking part in the Commission Deltaplan Mathematics. Commission chairman Jacob Fokkema announced that the Deltaplan is a starting point for a solid impulse of Dutch Mathematics. It contains an integrated policy for research, education, teacher training and society and innovation. PWN and NWO are committed to realize the Deltaplan. In a later stage, the plan will be presented to the Ministry of Education, Culture and Science (OCW).
Platform Wiskunde Nederland published its Vision document for Dutch Mathematics in 2014. The Deltaplan is a translation of the recommendations from the Vision document in concrete actions. It’s based on consults with rectors, deans, mathematicians, industrial partners and related parties. The result is a widely supported plan that is, just like the Vision document, written by policy makers of the Ministry of OCW and the Ministry of Economic Affairs, NWO, university presidents, deans and directors of mathematical institutes and mathematicians themselves.
PWN and NWO decided to collaborate and to for a Commission Implementation Deltaplan (CIΔ) under the supervision of prof. Frank van der Duijn Schouten. To stimulate the start of the realization of the Deltaplan, the chairman of the NWO division of Physical Sciences (NWO EW) prof. Arjen Doelman announced that NWO EW reserved around 2 million euro for the consolidation of mathematical clusters; one of the most important actions in the Deltaplan.

Stéphanie van der Pas wins the Leiden University Thesis Awards 2014 - published on (13-2-2014)
She proved that a new method to choose a research model works better than the usual standard method. The most commonly used selection method, the hypothesis test, has some disadvantages. She proved mathematically that the switch criterion, a Bayesian selection method, is more flexible than the known standard method. She looked at consistency, robustness against optional stopping and risk- optimality. After many calculations and formulating a proof of twelve pages the new method appeared to be good in multiple areas.
Van der Pas received the prize, a check for € 3000 , during the Dies Natalis for alumni on February 8, 2014 from Professor Carel Stolker, Rector Magnificus and Chairman of the Executive Board of Leiden University .

Phd student Frits Veerman selected for a Rubicon research grant in Oxford - published on (7-8-2013)
After his PhD defense on 25 September Frits Veerman will go to the University of Oxford to do research at the Centre for Mathematical Biology. Frits is the only researcher from Leiden University that was granted a Rubicon research grant. The Rubicon Program enables recently graduated scientists to carry out research at a foreign top institute, which is vital for building a scientific career. In the past four years, Veerman has been carrying out mathematical research under supervision of dr. Vivi Rottschäfer and Prof. dr. Arjen Doelman. His research focusses on applied analysis, in particular on pattern formation. It turns out that patterns in natural phenomena can often, from a mathematical perspective, be described in a similar manner. Veerman: ‘The remarkable thing about my research proposal for Oxford is that I am asking: How do patterns occur in environments that are themselves constantly changing?’ The researchers at the Centre for Mathematical Biology of Oxford University already have experience with studying patterns on growing biological domains, says Veerman. ‘Biologists and mathematicians work together to address questions at the interface between biology and mathematics. That’s why I chose Oxford. I’m looking forward to coming into contact with scientists from other disciplines. You can learn from each other’s research methods and approaches.’
