Senior Researcher

ifb Bamberg


I am Senior Researcher at the State Institute for Family Research at the University of Bamberg and Deputy Managing Director of the Journal of Family Research.

Previously, I worked as research assistant at the National Educational Panel Study and the Professorship of Demography at the University of Bamberg, as research fellow in the research group Demography and Inequality at the WZB Berlin Social Science Center, and Assistant Professor for Sociology in the Department of Sociology at the University of Mannheim. In 2011 I was a visiting pre-doctoral fellow at the Center for Research on Inequalities and the Life Course (CIQLE) at Yale University, New Haven. In 2014, I completed my PhD (“Family Effects on Family Formation”) at the University of Bamberg.

Sequence Analysis Resources

Sequence Analysis - Companion Site
Companion website for the little green QASS book on ‘Sequence Analysis’ by Marcel Raab & Emanuela Struffolino providing data and code to replicate the examples shown in the book & some bonus material
ggseqplot - ggplotify sequence data plots
This library (available on CRAN) provides functions to render sequence plots using ggplot2 instead of base R’s plot function which is used TraMineR::seqplot
seqquality - Sequence Quality Index
A little R function available via GitHub which computes a generalized version of the sequence quality index proposed by Manzoni and Mooi-Reci (2018).


Since I am working at the ifb, I reduced my teaching load and only teach one course per year at the University of Bamberg. In addition, I regularly offer sequence analysis workshops together with my colleague Emanuela Struffolino.
