I am a postdoctoral researcher in the Stochastics group at Humboldt-Universität zu Berlin, working with Markus Reiß. I am also part of the Collaborative Research Centre 1294 “Data Assimilation”.
My research lies at the intersection of statistical inverse problems, Bayesian nonparametrics, and inference for partial differential equations. I develop statistical theory for linear and nonlinear inverse problems. A particular emphasis is on spectral-cut-off estimation, posterior contraction, noise and model misspecification, uncertainty quantification, and minimax-theory.
I received my PhD in Mathematics from Heidelberg University in July 2026 under the supervision of Jan Johannes. During my doctoral studies, I was a member of the STRUCTURES Cluster of Excellence and undertook research visits at the University of Cambridge.
