About Me

(in about 587 words)

I am currently a postdoctoral researcher in the Mathematics and Computer Science division at Argonne National Laboratory with Stefan Wild. I obtained my PhD in Statistics from Virginia Tech in July 2019, where I worked on Stochastic Computer Model Calibration and Uncertainty Quantification with Prof. David Higdon.

Research Interest

My broad research interests include, but not limited to, scalable algorithm for calibrating large scale computer models, inverse problem, uncertainty quantification, and bayesian optimization. I am particularly interested in finding ways to represent model inadequacy that is meaningful and facilitates extrapolation. Check project page for more details into my research.
