Biography

Teresa joined Sandia in January 2020. Her research focuses on assessing and enhancing model prediction fidelity to inform high-consequence decisions for national security applications, especially in the presence of uncertainty. She has expertise in methods to characterize model-form uncertainty, sensitivity analysis, Bayesian methods, and multifidelity uncertainty quantification. She has worked on a range of applications, including disease modeling, nuclear waste repository modeling, ablation modeling for hypersonics, thermal batteries, and structural dynamics for aerospace problems.
