Doctoral students associated to the research training group

In order to establish a vibrant research environment and to enhance the structured PhD education in statistics at the universities of Heidelberg and Mannheim the research training group associates externally funded PhD students. The students participate in training events and contributed with their knowledge to the research of the funded PhD students and research students.

Nicolas was born in Mulhouse, France, in 1989. He received his B.Sc. (2010) at University of Upper Alsace (Computer Science and Mathematics) and M.Sc. (2012) at University of France-Comte (Statistics and Mathematical Statistics). Since 2012 Nicolas is a PhD Student and teaching assistant at Université catholique de Louvain, Belgium. His research focuses are adaptive non-parametric estimation, mini max theory and statistical ill-posed inverse problems.

Stefan was born in Marburg, Germany. He received a diploma in Taxation and Finance at the VFHS Rotenburg a.d.F. and subsequently worked for the government.  During this time he got in contact with topics in the area of business mathematics. This motivated him to study business mathematics at the Philipps-University Marburg where he completed his Bachelors Degree in 2012 and his Masters Degree in 2015. Since January 2015 he works as a PhD student and research assistant at the institute of mathematics at the University of Mannheim in the team of Prof. Dr. Martin Schlather. Stefan’s research field is the extreme value theory concerning weather extremes and econophysics.
