ServiceI have worked on the following OECD projects as a research analyst -
1. Causal Effects of Health on Literacy and Training Participation. (with Clemens Lechner)
2. PIAAC Field Trial Study
3. Comparative Analysis of Student Skill Scales in the Study of Social and Emotional Skills (with Clemens Lechner and Matthias Blümke) To top
ResearchBroadly, my main research interests are in data quality assessments, latent variable modeling, categorical data analysis, and research methods. I like to use these methodologies to answer pressing research questions in the field of social sciences.
Specifically, my current research interests are:
Response Quality Assessment
Modeling Zero-Inflated Count Data
