My name is Paweł Lenartowicz. I am an independent scientist devoted to statistics and metascience, with a lean towards social sciences, psychology, and neuroscience. I currently study psychology and computational mathematics at Jagiellonian University in Kraków, Poland.
I believe that good statistical tools and education should not be limited by unnecessary complexity, mathematical jargon, or programming requirements. I spend my time creating methods, software, and educational resources that help scientists and students better understand and simply use statistics.
Research Interests
- Monte Carlo methods — simulation-based approaches to power analysis, permutation tests, and bootstrapping
- Publication bias and metascience — detecting and quantifying biases in scientific literature, estimating replicability
- Neurocorrelates of consciousness — data-driven verification of neural theories of consciousness
- Open science — promoting transparency, replicability, and good research practices
Affiliations
- Society for Open Science — Chairman and founder. The association promotes collaboration, transparency, and methodological rigour in research.
- Center for Brain Research, Jagiellonian University — Working on neurocorrelates of consciousness in the project "Verification of assumptions of neural theories of consciousness in a data-driven approach".
