"Logic is the foundation of the certainty of all the knowledge we acquire."

In my opinion, for every problem there is always a satisfying solution. Even though it might be easy to find a solution for a given problem in the first place, this solution might be far from being optimal. Sometimes it might even be impossible to find the solution we are seeking and we might end up choosing the lesser of the two evils. I always liked thinking about how to crack down on a problem, which might be one of the reasons why I started studying mathematics in the first place. The latter not only taught me the tools to look efficiently for that mysterious X everybody is talking about, but sooner than later I noticed that it helpes me to analyze and solve problems in general, which do not necessarily need to be related to mathematics.

I am largely interested in optimization, modelling, machine learning, problem solving, cryptography and all sort of applying mathematics to the problems our society is facing. The beauty in mathematics lies in the fact that it enables us to solve complex problems, to make life easier and to provide the necessary knowledge to help our society.

I hold a Bachelor and Master in Mathematics from the University of Luxembourg, during which I specialized in Industrial Mathematics as well as computer science, programming and data analysis. At the moment, I am an applied mathematician at IEE S.A. doing my Ph.D. in Deep Learning.
