South San Francisco, California, United States
Summary
👤
Senior🎓
Top SchoolCharles Greenberg is a Machine Learning Engineer with 12 years of experience applying deep learning and probabilistic methods to health sensing, biomedical imaging, and large-scale sensor data. After a PhD in Biophysics at UCSF and early physics research, he built clinical-risk and explainable-deep-learning systems at Lumiata, advanced health sensing and bias-mitigation methods at Apple, and now works on next-generation wearables at Meta. He specializes in self-supervised learning, model validation that extrapolates study results to populations, and interpretable approaches that reduce demographic bias in deployed models. Equally comfortable with Bayesian uncertainty modeling from his structural-biology work and production ML pipelines, he blends rigorous research instincts with product-focused delivery in regulated health contexts. An understated strength is his track record of translating complex academic methods (Gaussian processes, Monte Carlo sampling) into robust, explainable systems used by cross-functional teams and executives.
