Summary
👤
Senior🎓
Top SchoolPetra Lenzini is a research statistician with nine years of experience improving data and informatics pipelines for trans-omics and neuroimaging research at Washington University in St. Louis. She designs and implements reproducible pipelines that harmonize clinical, imaging, and genomic data from sources like UK Biobank, HCP, REDCap, and XNAT, and she has hands-on expertise with cloud-enabled tools (DataLad, brainlife.io) and high-throughput bioinformatics workflows. Her technical toolkit spans SAS, R, Python, Bash, LSF/Grid Engine, and a wide array of genomics packages (minfi, MMAP, Epacts, SHAPEIT, Minimac) as well as microbiome and expression analysis pipelines. Petra pairs rigorous statistical methods—mixed GLMs, survival analysis, EWAS/GWAS workflows, and power analysis—with clear stakeholder communication to streamline data movement and reduce redundancies across multi-center studies. She also provides public user support, writes grants and protocols, and has a background in fine arts, giving her a distinctive blend of analytical precision and visual/communication sensibility.
