I am a Professor in the Department of Economics and Business Economics at Aarhus University. My expertise lies at the intersection of quantitative research methods and business analytics.
My research advances statistical methodology in organizational science through the development of techniques for statistical and causal inference. I have made contributions to statistical practices through my work on sample size-dependent alpha levels, multiple imputation for multilevel data, generalized linear models, Bayesian multilevel models, and sensitivity analysis using the Impact Threshold for Confounding Variables (ITCV).
While my primary focus is on resolving statistical challenges in management research, I regularly apply my data science expertise to interdisciplinary projects spanning corporate finance, social epidemiology, and public administration.
My research appears in Journal of Management, Organizational Research Methods, Journal of International Business Studies, The Leadership Quarterly, Public Administration Review, Journal of Corporate Finance, and Strategic Organization.
I currently serve as an Associate Editor and Method Reviewer for The Leadership Quarterly and as a Methods Consultant for the Journal of Management Methods Task Force, where I help shape methodological standards in organizational research.
