About Hao Zheng

I work at the intersection of healthcare data and business decisions.Most of my work focuses on patient-level data — not just analyzing it, but making sure the conclusions are actually valid. In commercial and real-world data settings, results can often look reasonable but be biased depending on how comparisons are structured.I specialize in stress-testing analyses, identifying hidden biases, and ensuring that insights hold up to scrutiny before they inform decisions. My work spans vaccine analytics, commercial program evaluation, and real-world evidence, with direct experience partnering with pharma stakeholders.I’m particularly interested in roles where data complexity is high and getting the analysis right truly matters — especially in areas involving heterogeneous patient populations and real-world data.
