Senior🎓
Top SchoolZixuan Z is a postdoctoral fellow in statistical genetics at the University of Pennsylvania with eight years of experience developing scalable statistical and computational tools for genetic association and single-cell eQTL mapping. Holding a PhD in Biostatistics, they built JAX-powered software (FactorGO and jaxQTL) that scales to millions of variants and thousands of traits and was validated on large biobank and single-cell datasets. Their work spans Bayesian and count-based modeling, cloud-scale data processing, and interactive R Shiny apps for results exploration, reflecting a rare combination of statistical rigor and production-grade software engineering. Zixuan has taught parallel computing and HPC workflows, interned in industry on Bayesian trial design, and brings hands-on experience optimizing models for CPU/GPU/TPU—helpful when translating research methods to reproducible tools.
