Biography

Tian Yu joined Sandia as a postdoc in 2021. His current research focuses on methods of aleotoric and epistemic uncertainty quantification for inverse problems as well as techniques for quantifiying uncertainty in machine learning algorithms. He has a background is in measure-theoretic inversion, Bayesian inference, and statistical density estimation. His personal vision and mission statement is included below.

"Through my career in mathematics, I aim to train and mentor the next generation of STEM professionals–especially those individuals who have faced systematic and historic barriers to the field. By pursuing impactful research and demonstrating inspiring leadership, I work to make rigorous mathematical thinking and advanced statistical tools accessible to all who seek them."
