The aim of the BSSM is to present, in a<br>friendly atmosphere, to secondary school students, teachers and university students<br>different aspects of mathematical sciences and research, as well as their inherent<br>joy, beauty and usefulness. After 3 students in the first year (2007), the BSSM now<br>has each year about 100 participants (the 6th edition in 2013 was the last year he<br>took part in the organization). In 2012, he received the Wernaers Prize for the idea<br>and organization of the BSSM.<\/p>\n\n<p>In September 2024, he was invited to the Round Table as a participant at REEL2024 to discuss about digitalization, future and education in Cologne. Furthermore, he participated in several talks and events, such as &#8220;MATh.en.JEANS&#8221; with high-school students from the Lyc\u00e9e Classique Diekirch, giving valuable insights into his knowledge in the mathematical field.<\/p>\n<\/div><\/div><\/li>\n\n<li class=\"list-highlighted__item  wp-block-unilux-blocks-highlighted-list-item\">\n    <header class=\"list-highlighted__header wp-block-unilux-blocks-highlighted-list-item-header\">\n    \n<h4 class=\"title text-18 font-bold has-text-align-left wp-block-unilux-blocks-heading\"        id=\"awards\"\n    >\nAwards<\/h4>\n<div class=\"wp-block-unilux-blocks-bigtext\">\n    <span>\n        \n    <\/span>\n<\/div><\/header><div class=\"list-highlighted__body wp-block-unilux-blocks-highlighted-list-item-body\">\n    <div class=\"wp-block-unilux-blocks-highlighted-list-item-free-content-area\">\n    \n<ul class=\"ulux-list\">\n<li class=\"ulux-list-item\"><strong>2024: <\/strong>Teaching Award of the ±¬ÁϳԹÏÍø<\/li>\n\n\n\n<li class=\"ulux-list-item\"><strong>2024: <\/strong>Selected as candidate for the FNR Pairing Scheme &#8211; Politics Meets Research<\/li>\n\n\n\n<li class=\"ulux-list-item\"><strong>2024: <\/strong>Bernoulli Prize for an Outstanding Survey Article in Probability or Statistics for the<br>paper \u201cChristophe Ley, Gesine Reinert, Yvik Swan &#8220;Stein\u2019s method for comparison<br>of univariate distributions.&#8221; Probab.
