We are very honoured to give our support to Charles Leytem (IMO team leader), Pascal Zeihen (IMO team deputy leader and trainer), Bernard Felten (BxMO team leader), Pierre Haas (EGMO team leader) and Mike Dostert (general secretary for all competitions and trainer) for their work to promote mathematics.

**Who we are:**

He participated with Colombia in the math Olympiads between 2004 and 2008, obtaining a silver medal at the IMO. He studied mathematics in France, in Paris, at the École Normale Supérieure and the University Pierre et Marie Curie, where he obtained his PhD in 2017. After a year in Nancy, he arrived to the University of Luxembourg as a research assistant in the Geometry and Topology team.

* When I was in the math Olympiads, I had very good moments and I could learn many fascinating things,
while being challenged by mathematical problems. It was during this time that I decided that I wanted to work on math.
I am very grateful to the Olympiads in general and to the Colombian Math Olympiads in particular!

He studied Mathematics in Germany at the University of Trier, where he graduated with a PhD in 2011. He then became a postdoctoral researcher at the University of Luxembourg in the domain of Geophysics, before he joined the Scienteens Lab in early 2017, where he is responsible for the workshops in Mathematics.

* At the Scienteens Lab, one of our main goals is to arouse young people's interest for mathematics.
By joining the Maths Team and supporting this online training course,
I hope to make a further contribution to motivating pupils for this beautiful subject! *

In 1999 she was selected to train with the italian IMO-team, and was admitted at only 17 to the Scuola Normale Superiore in Pisa. She then worked in several countries (I, CH, F, NL, B, CA, D) before joining the University of Luxembourg. Her research areas are Number Theory and Algebraic Geometry.

*Because of mathematical contests I have met amazing people, and discovered a whole new world...
I was also better prepared for University tests and for challenges in general. I would do it again, anytime!*

He completed his Bachelor in Mathematics in Trento, Italy. Later he completed the Algant Master Programme and obtained a joint Master degree from the universities of Milan (IT) and Leiden (NL). Since 2018 he is a PhD student at the University of Luxembourg, working in Number Theory and Arithmetic Geometry. He has competed multiple times in Mathematics and Computer Science contests (IOI).

*Until high school, I thought Math was boring and I didn't like it.
But then I discovered the Olympiads and other contests, and I found out that Math problems can be so much fun!*

He studied mathematics in Heidelberg and Cambridge, and then worked in France, The Netherlands and Germany before moving to Luxembourg in 2011 as a professor of mathematics. He does research in Number Theory and Computer Algebra.

*When I was at school, I loved to play with mathematics.
But it was only at the university that I got challenging problems, and truly learnt to appreciate the beauty of mathematics.
By accompanying this course, I hope to help some pupils have fun with mathematics.*
