Germany - Last active: 05/02/2014 - Tests: 1

Simply put I love solving real life problems through mathematics and data science is the ideal way to keep enjoying science while answering exciting business questions and turning ideas into business opportunities. As applied mathematician, I will combine my experience of interdisciplinary scientific research and of international team work. I worked in ONERA, the French aerospace lab during my awarded PhD in applied probability and succesfully at BASF in the polymer engineering department as a model developer. Besides, I have completed this experience with statistics skills and machine learning knowledge. Furthermore, I have a friendly communicative personalty. Actually, I can convey technical content in a very simple way. The clarity and the simplicity of my communication style precisely earned me the ONERA PhD Award 2011 atop the quality of my research and my publications. I know how to walk my audience through a technical problem so that the added value is seen and understood, which is the alpha and omega of creative discussion and innovative solutions. Eventually, my appetite for international environment led me to become the president of the local group of a Pan-European student network and will facilitate working with colleagues from all over the world. I would be delighted to add my skills to the success of your projects.
