Ingeborg Waernbaum

Ingeborg Waernbaum is a Professor at the Department of Statistics, Uppsala University, and a Researcher at the Institute for Evaluation of Labour Market and Education Policy (IFAU). Her work bridges biostatistics, causal inference, and epidemiology, with a focus on observational studies and methodological innovations.

• Primary Affiliation: Department of Statistics, Uppsala University
• Secondary Affiliation: IFAU (Institute for Evaluation of Labour Market and Education Policy)

Her research centers on:

• Causal inference methodologies for observational data
• Propensity score modeling and doubly robust estimation
• Selection bias bounding and sensitivity analysis
• Applications to diabetes epidemiology and socioeconomic health disparities

Recent publications (2023-2025) highlight her dual focus on theoretical advances in causal effect estimation (e.g., entropy balancing, mediation analysis) and applied biostatistical studies in diabetes and public health. She has developed R packages for selection bias bounding and covariate selection, emphasizing practical tools for researchers.

Key methodological contributions include:

• Clarifying limitations of doubly robust estimators
• Advancing sensitivity analysis for unmeasured confounding
• Examining efficiency trade-offs in propensity score methods

Applied work spans:

• Diabetes incidence trends and complications
• Socioeconomic determinants of health outcomes
• Fracture risk analysis in pediatric populations

She actively engages in:

• Register data analysis
• Statistical software development (R packages)
• Methodological critiques and robustness studies
