Stephan's main research interests are geometry and topology with a focus on low-dimensional manifolds. He uses techniques from algebraic geometry, hyperbolic and projective geometry, geometric group theory, representations of finitely generated groups, differential geometry as well as tropical geometry.
A principal aim of his current research is to understand the relationship between triangulations of, geometric structures on, and surfaces in 3-manifolds with view towards new topological results about 3-manifolds, practical algorithms, and applications to group theory.
