I am Assistant Professor of Statistics at the University of Bonn.

My research interests focus on functional data analysis, semi- and nonparametric statistics, and longitudinal data analysis.

Work in Progress

  • Super-consistent estimation of points of impact in nonparametric regression with functional predictors (with Poß, D., Kneip, A., Eisenbarth, H., Wager, T. D., and Feldman Barrett, L.)

  • Take off your shoes! Analyzing the foot strike behavior of habitual shod runners when running barefoot (with Willwacher, S., Hamill, J., and Brüggemann, G. P.)

  • Footstrike adaption to barefoot running (with Willwacher, S.)

  • A subsampled penalty criterion to estimate the number of non-vanishing common factors in large panels (with Bada, O.)

  • On the minor role of bandwidth selection when smoothing sparse to dense functional data

  • Observe the unobservable: Firm value and firm-specific heterogeneity in time trends (with Gider, J.)

  • Life-cycle wage trajectories with missing data: A factor analytic approach (with Pinger, P.)

Software

  • Together with my co-author Oualid Bada, I am the creator and maintainer of the R-package phtt. The package provides estimation procedures for panel data with general forms of unobservable heterogeneous effects.

  • R-package PartiallyFD (developed by my co-author Stefan Rameseder)

  • R-package ReconstPoFD
