Dr. Steffen Schuldenzucker

Since September 2019, Steffen is a PostDoc at the Algorithms and Complexity Research Group at Goethe University Frankfurt funded by an SNF Early Postdoc.Mobility Fellowship.

Steffen joined the Computation and Economics Research Group as a PhD student in 2014. In 2019, he completed his dissertation, advised by Sven Seuken, titled A Formal Analysis of Complexity and Systemic Risk in Financial Networks with Derivatives (grade: summa cum laude). Steffen holds a BSc (2012) and a MSc (2014) in Mathematics from the University of Bonn, Germany.
