## Short Bio

Chao Yang got his Ph.D in computational mathematics from Rice Universisty in 1998. He worked at NEC Systems Lab, Inc, a subsidiary of NEC from 1998 to 1999. He was awarded the 1999 Householder fellow in scientific computing by Oak Ridge National Laboratory. He joined Lawrence Berkeley National Laboratory in 2000, and is currently a staff scientist. His research interests include:

- developing numerical algorithms and fast implementation to accelerate scientific simulations
- developing efficient and robust algorithms and implementations for solving inverse problems

His core expertise is in numerical linear algebra, optimization, and high performance computing. Over the last several years, he has successfully applied the latest development in these areas to solve problems in electronic structure calcuations, nuclear structure calculations, cavity design for accelerator models, single-particle analysis for cryo-electron microscopy, single molecular diffractive imaging, phase retrieval, ptychography etc.
