Elizabeth Qian

von Kármán Instructor at Caltech

I am a von Kármán Instructor in the Department of Computing + Mathematical Sciences at Caltech. My research lies at the intersection of computational science and engineering application, and is motivated by the need for computational methods used in engineering decision-making to be efficient and scalable. In particular, I am interested in model reduction and scientific machine learning for engineering systems, and in multi-fidelity formulations for uncertainty quantification and optimization.

I completed my PhD in Computational Science & Engineering at MIT, where I worked with Karen Willcox as a student in both the Center for Computational Science and Engineering and the Department of Aeronautics & Astronautics. As a graduate student, I was supported by the NSF Graduate Research Fellowship and the Fannie and John Hertz Foundation Fellowship. Prior to starting graduate studies, I spent a year on a Fulbright at RWTH Aachen University working with Karen Veroy-Grepl and Martin Grepl. I obtained my SB and SM degrees in Aerospace Engineering from MIT in 2014 and 2017.

Upcoming talks & activities

Jan/Feb 2022: I will chair Caltech's Computational Mathematics + X Seminar in our winter term. Very excited to host speakers Alexandria Volkening, Talea Mayo, Ron Buckmire, and Chad Topaz.

April 2022: At SIAM UQ 2022, I will present our work on Balanced truncation for Bayesian inference on Tuesday, April 12. I am also co-organizing with Sven Wang a minisymposium on Statistical and Computational Guarantees for Bayesian Inverse Problems on Thursday, April 14.

Recent news

December 2021: I presented our work on Balanced truncation for Bayesian inference at the Women in Inverse Problems virtual workshop hosted by Banff International Research Station Dec 5-10.

November 2021: Our manuscript, Model reduction for linear dynamical systems via balancing for Bayesian inference, is on arXiv. This work is a collaboration that grew out of the ICERM Semester Program on Model and Dimension Reduction.
