March 2015 Master of Science at Freie Universität Berlin
I wrote my master thesis on
Approximating Primitive Integrals and Aircraft Performance (09/2014 - 03/2015) in the area of Graph Theory and Optimization under the supervision of
Prof. Dr. Ralf Borndörfer. The research was part of the
Flight Trajectory Optimization on Airway Networks project at the Zuse-Institute Berlin (ZIB). The main industry partner of this project is Lufthansa Systems Frankfurt. Furthermore it is part of the joint project
E-Motion - Energieeffiziente Mobilität which is funded by the German Ministry of Education and Research (BMBF).During the course of my research I was employed as a student research assistant at the ZIB (05/2014 - 03/2015).
September 2012 Bachelor of Science at Freie Universität Berlin
I wrote my bachelor thesis on
Numerical Pricing of Financial Derivatives (06/2012 - 09/2012) under the supervision of
Prof. Dr. Carsten Hartmann.
