Carl Falk is an associate professor of quantitative psychology at McGill University with a decade of experience developing and implementing advanced latent variable models across behavioral and health sciences. He combines deep methodological expertise in item response theory, structural equation and multilevel modeling with practical skills in Bayesian statistics, categorical data analysis, and network modeling. A former computer/web programmer, he writes custom implementations in R, Python, Java, C/C++ and Stan and co-authors multiple R packages, often pairing theoretical innovation with large-scale simulation studies. His research spans theory-to-practice: detecting item misfit and aberrant or bot-driven responses in surveys, handling messy real-world data, and designing model selection tools that help substantive researchers make defensible inferences. Based in Montreal, he is known for translating complex quantitative methods into accessible tutorials and collaborative applied work that directly improves measurement and causal inference in applied domains.
