**Dr Atle Hahn** (right in picture) is a mathematician with a PhD in Applied Mathematics
from the University of Bonn (2001, Department for Probability Theory
and Statistics). From 2007-2017 he worked as a Researcher in Pure and Applied Mathematics and as a Lecturer at the University of Lisbon.
His fields of specialization are Mathematical Physics, Stochastic Analysis,
Statistical Learning Theory, and Deep Learning (in particular, Deep Reinforcement Learning).
He received scholarships from the “Studienstiftung des deutschen Volkes”
and the “Alexander von Humboldt-Gesellschaft”, and was an invited speaker
at research institutions in Berkeley, Tokyo, Kyoto, Nagoya, Beijing
and the MPI for Gravitational Physics in Potsdam. He is fluent in German, English, Portuguese, and Norwegian. Atle’s favourite programming language is Python but he also occasionally uses C.

**Dr Erich Steiner** (left in picture) is a mathematician and did his PhD in numerical
analysis and optimization at the
University of Edinburgh and his Bachelor/Master at Cambridge University.
He worked as a software engineer in the area of data management, analysis and statistical prediction
models for various companies for 15 years. He is also very interested in the mathematical modelling
of optimization problems. In this category falls automated dispatching with heuristics and
combinatorial optimization.
He lived in Britain for 8 years and speaks fluent English. German is his mother language.
He also worked in France and Italy and speaks French and Italian enough for explanations in courses.
His favourite programming language is Python but he used to program a lot in Java and Fortran95.
