About Me
I am a staff research scientist in the Optimization and Uncertainty Quantification department at Sandia National Laboratories. Prior to my current position at Sandia, I was a PhD Student in the Computational Science, Engineering and Mathematics PhD Program, housed in the Oden Institute for Computational Engineering and Sciences at UT Austin. My research interests include:
- model-form uncertainty (model-form error/model inadequacy/model discrepancy)
- Bayesian inference
- sensitivity analysis
- multimodel (multilevel/multifidelity) uncertainty quantification
- validation and reliability of computational models used for prediction
I am an avid cook, choral singer, and photographer.
