Rockstar🎓
Top SchoolWaldir Leoncio is a Research Software Engineer in Oslo with 11 years of experience applying rigorous statistical training to build reproducible research software and scalable data pipelines. With a Ph.D. in Statistics from Padova and a background merging large administrative datasets at Brazil’s AGU, he blends deep methodology with practical engineering—authoring R packages and automating heavyweight ETL and reporting workflows. At the Oslo Centre for Biostatistics and Epidemiology he serves as a senior scientific programmer, translating complex measurement and epidemiological problems into reliable code and tools. He has a track record of shipping open, reproducible research artifacts from his Ph.D. and visiting research, and he teaches statistical measurement principles as well. Quietly versatile, he moves between hands-on R development, research dissemination, and production-grade data engineering, making him a bridge between statisticians and software teams.
