Joscha Diehl graduated from TU Berlin in 2012, with a thesis on stochastic differential equations and rough path theory.
Having a background in stochastic analysis, he recently became interested in algebraic questions related to the signature of curves. These signature tensors carry relevant (nonlinear) information about the curves and appear in control theory, stochastic analysis, and time series analysis.
The algebraic questions he is addressing during his stay at MPI MiS connect to non-commutative algebra, commutative algebra, invariant theory, and combinatorics.
