Biographical Data
Main areas of research
Christian has a broad, interdisciplinary interest within the areas of systems & control, optimization and machine learning. Specifically, he is interested in synergies that arise from positivity/invariance theory. This includes positive/monotone systems, harmonic analysis, sparse/low-rank optimization, model order reduction, system identification, nonnegative matrix factorization and deep learning.
