Joshua Rubin is Head of AI Science at Fiddler AI with a decade of experience applying deep learning and statistical modeling to real-world problems, from calibration and signal processing to AI explainability and dataset shift detection. He rose through multiple technical and leadership roles at Fiddler, combining hands-on model development with team direction and product-focused research. Trained as an experimental particle physicist (PhD, UIUC) he brings rigorous measurement, uncertainty quantification, and reconstruction expertise to ML problems. Joshua is particularly interested in semantic matching and building interpretable tooling that surfaces when models and data diverge. His background includes founding a startup and contributions that span industry consulting and national-lab experiments, reflecting a mix of entrepreneurial drive and scientific rigor. Off the clock he cultivates patience and attention to detail as a devoted vegetable gardener.
