Stéphanie van der Pas wins the Leiden University Thesis Awards 2014 - published on (13-2-2014)

image Stéphanie van der Pas won the Leiden University Thesis Awards 2014 with her thesis "Almost the Best of Three Worlds: The Switch Model Selection Criterion for Single Parameter Exponential Families."

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 .

The jury described the thesis of Van der Pas, who completed the Master of Applied Mathematics with honors, as "brilliant, humorous and of broad significance for scientific practice ".

Stephanie is currently PhD student at the Mathematical Institute.


Prof. dr. Lenstra in tv show 'De Wereld Draait Door' - published on (7-2-2014)

In the tv show 'De wereld draait door' of Tuesday 4 February, Prof. Hendrik Lenstra, together with Prof. Barry Koren, gave an explaination of the so-called 'Milleniumproblems'. In 2007, the Clay Mathematics Institute offered 1 million dollar for each solution of 7 mathematical problems. The Kazach mathematician Muktharbay Otelbayev now claims to have found the solution for 1 of the problems. To view the show of 4 February, click here.

NWO Gravitation Programme awarded 10-year grant to research consortia 'Networks' - published on (20-12-2013)

image Professor Frank den Hollander has been awarded a 10-year grant through the NWO Gravitation program, jointly with colleagues from the University of Amsterdam, the Center for Mathematics and Computer Science in Amsterdam, and the Technical University of Eindhoven. The grant supports a project called "Networks", which aims to address the pressing challenges posed by large-scale networks. The focus is on modeling, understanding, controlling and optimizing networks that are complex and highly volatile. The project brings together researchers from stochastics and algorithmics.

The total funding is 22.7 Million Euro from the Dutch Ministry of Education, Culture and Science (OCW), with an additional matching of 5 Million Euro by the participating institutions. On 18 December 2013 the laureates were welcomed at NWO by the minister of OCW and were handed the prize.

In March 2013, 41 proposals were submitted by universities, of which the international selection committee selected 6 proposals for funding.


Stéphanie van der Pas wins ASML Graduation Prize Mathematics for analysis new research method - published on (25-11-2013)

On November 29, Stéphanie van der Pas receives the ASML Graduation Prize for Mathematics at the Royal Holland Society of Sciences (KHMW) in Haarlem. 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 stops and risk- optimality. After many calculations and formulating a proof of twelve pages the new method appeared to be good in multiple areas.

By colleague statisticians and the jury the graduation work of Stéphanie is considered a mathematical masterpiece. The jury praises her elegant mathematical reasoning beyond the standard methods in the field.

Since her graduation Stéphanie works as a PhD student at the Mathematical Institute.
