Research Interests and Recent Research Directions

I am interested in developing numerical algorithms and software for scientific computing. My researches usually involve numerical linear algebra, computational optimization, parallel computing, and their applications. Here is my publications list.

My recent projects include the following topics.

Matrix Computations with Applications in Physical and Data Science.
We consider large-scale linear systems, nonlinear eigenvalue problems, and matrix factorizations arising in numerical simulations and data analytics. The applications include three-dimensional photonic devices, dimension reductions for big data, and healthcare. The main focuses include Krylov type algorithms, randomized methods, and accelerations on parallel computers with GPU.

Data-Driven Modeling and Statistical Computing.
Many computer experiments require performance analysis and optimization in which only objective function values are available. Our main focuses are design of experiments and surrogates models assisted techniques with emphasis in software auto-tuning. We also develop efficient methods for statistical computing and optimal experiment designs.

GPU and High-Performance Computing.
We study how GPU, multicore-CPU, and heterogeneous CPU-GPU clusters can be used to accelerate scientific computations. The focuses include CPU-GPU accelerated solvers for linear systems and eigenvalue problems, fast medical image reconstructions on computed tomography, and particle swarm optimization with applications in medical and statistical sciences.
