Ziyi “Francis” Yin - 尹梓屹
About me
I will be joining the subsurface innovation lab at Occidental Petroleum Corporation as a geophysicist resident.
I earned my PhD degree in Computational Science and Engineering at Georgia Institute of Technology in 2024, advised by Prof. Felix J. Herrmann. I earned my BSc degree in Mathematics and Computer Science at Emory University in 2019, advised by Prof. James G. Nagy.
A super 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
