Ziyi “Francis” Yin - 尹梓屹
About me
I am a PhD candidate in Computational Science and Engineering at Georgia Institute of Technology, advised by Prof. Felix J. Herrmann. I am a member of the SLIM (Seismic Laboratory for Imaging and Modeling) group.
A high-level summary of my research is high-dimensional Bayesian inference for computationally expensive parameter-to-observable maps. Generally, my research interests include:
- scientific machine learning
- large-scale inverse problems
- high-performance computing
- PDE-constrained optimization
- numerical modeling and simulation
- uncertainty quantification
- simulation-based inference
- and their application in geophysical inversion
Before coming to Georgia Tech, I graduated from Emory University in 2019, with a summa cum laude Bachelor of Science degree in Mathematics and Computer Science. I conducted research on regularization methods for image reconstruction from CT scans, advised by Prof. James G. Nagy and wrote my honors thesis, Edge Detection and Enriched Subspaces.
