[School of Natural Sciences PhD Scholarships] Mixed-Precision Randomized Numerical Linear Algebra

About the project

About the Project Modern scientific computing and data analysis increasingly involve matrices that are too large for traditional numerical algorithms to handle efficiently. Randomized numerical linear algebra addresses this challenge by using random sampling and sketching to construct smaller problems that retain the important information in the original data. At the same time, modern CPUs and GPUs increasingly provide very fast arithmetic at reduced precision, driven in part by developments in artificial intelligence. This PhD project will explore how these two rapidly developing areas, randomized algorithms and mixed-precision computing, can be combined to design faster and more efficient numerical methods without sacrificing the accuracy and reliability required in scientific computing. The student will develop and analyse new algorithms for problems such as low-rank approximation, least squares, and eigenvalue or singular value computation. The project will combine mathematical analysis, algorithm design, and computational experiments, providing training at the interface of numerical linear algebra, randomized algorithms, and high-performance scientific computing. This project is expected to start in September 2027. Before you apply: We strongly recommend that you contact the supervisors for this project before you apply.
