Dr. Tegan Emerson is a Chief Data Scientist in the National Security Directorate at Pacific Northwest National Laboratory. She leverages her mathematics background to develop data science solutions in support of the DOE mission. Specifically, Dr. Emerson focuses on assuring AI in high-consequence settings; both developing models that are assured by design and improving, evaluating, and understanding assurances for frontier models. Her work and technical leadership has supported innovations in hyperspectral imaging, overhead image analysis, models of atmospheric turbulence, signal processing, neuroscience, medical imaging, materials science, and many other application domains. Dr. Emerson’s research interests include geometric and topological data analysis, dimensionality reduction, image processing, generative AI, and optimization. In 2022 Tegan, along with two of her PNNL colleagues, founded a collaborative research community in topology, algebra, and geometry in data science which has grown to include over 1000 researchers across the world.
