About

Hi, I’m Konstantin. I am a research fellow in the Social Data Science group at Bielefeld University and at the Leibniz ScienceCampus SOEP-RegioHub, a joint project of Bielefeld University and DIW Berlin. Since September 2026 I am also a doctoral researcher in sociology at the Bielefeld Graduate School in History and Sociology (BGHS).

In my dissertation I study short-form video: which parts of a clip carry its meaning (the picture, the sound or the words), and what this means for researchers who want to code such videos at scale. At SOEP-RegioHub I build search tools that help people find survey and regional data. Besides that, I work on content sharing in the German regional press, on how diets spread within households, and on political language in parliament.

If any of this is close to your own work, I would be glad to hear from you.


Research Interests


Dissertation

My dissertation has the working title Short-Form Video as Data for the Social Sciences: Validated Multimodal Measurement of Online Communication. I started it at the BGHS in September 2026, and Simon Kühne supervises it.

It consists of four papers. I begin with everyday videos, where most things are easier to measure, and then move on to political content.

Papers
Paper What it is Status
P1 Which modality carries which construct in everyday short-form video In progress
P2 A typology and reporting standard for multimodal coding, with S. Kühne Conceptual
P3 Model choice and annotation budgets Planned
P4 The same questions for political short-form video Planned

Projects

Academic projects

Eating Together, Eating Alike

With Simon Kühne and Kerstin Ostermann, I look at how vegetarian and vegan diets spread within households and how long they last, using the German Socio-Economic Panel. A working paper is in progress.

Content Sharing in the German Regional Press

Many German regional newspapers print the same articles. I trace which titles share text with which, and how ownership, size and geography shape these flows. The newspaper texts are licensed, so only aggregated results leave the corpus. Two manuscripts are in preparation.

Semantic Drift in Parliamentary Speech

Together with Leon Gawenda, I use text embeddings to follow how political language, and the way politicians speak about places, changes over time in parliamentary speech.

Who speaks for the left-behind? Framing of spatial inequalities in the House of Commons (1988–2019)

With Chen Zeng and Leon Gawenda, I look at how British MPs speak about regional inequality in the House of Commons over three decades.

SOEP-RegioHub projects

GeoLAB

At SOEP-RegioHub I work on GeoLAB, which supports regional analyses with the SOEP: finding regional data, linking it to the survey, and keeping the way to the data reproducible.

Metadata search

The search behind GeoDB and the SOEP Variable Finder. It indexes the descriptions of datasets and variables, and the data themselves stay with the institutions that publish them.

Tools

GeoDB

GeoDB, short for GeoDataBase, lets you search German regional data from statistical offices and other public sources, by spatial level, theme and year. Each result takes you to the portal that holds the data.

Parliamentary Speech Finder

Search Bundestag speeches since 1949 (GermaParl) by topic. You get the original speeches, ranked by how close they are to your query, and no generated summaries.

badata

An R package with regional labour-market data from the German Federal Employment Agency, by district and occupational group. I am one of its authors, together with H. Long Nguyen and Dorian Tsolak.
