Summary

Senior🎓
Top SchoolLeah Comment is a Senior Principal Statistical Scientist with 11 years of experience applying Bayesian and frequentist causal inference to real-world health data, currently shaping statistical research at Genentech. She builds methods at the intersection of causal inference and decision theory to enable scalable clinical decision support and evidence-generation tools, drawing on prior leadership roles in decision sciences and causal modeling at Foundation Medicine. Her technical toolkit includes Bayesian modeling, ensemble learning, and data-driven sensitivity analysis, informed by training in health policy, economics, and human biology. A Harvard-trained biostatistician, Leah has tackled problems from semicompeting risks to data integration for unmeasured confounding, and she’s driven by a vision of learning health systems that deliver personalized care. Less obvious: she pairs deep methodological research with pragmatic prototyping of ML-driven decision support for oncology, bridging theoretical rigor and real-world deployment.
