Research Interests
My research group focuses on high-performance computing. In particular, we have been accelerating various scientific computing applications on GPUs and multicore CPUs. We also conduct basic research on algorithmic improvements for high-performance computing.
Note: Although I'm no longer doing research on the following topics, you can find more information about my prior research in wireless sensor networking and interconnection networks at my archived website.
As part of our research efforts, we contribute to the software development of two open-source software projects: GOMC and JETSCAPE.
GOMC
GOMC is open-source software for simulating molecular systems using the Metropolis Monte Carlo algorithm. The software has been written in object oriented C++, and uses OpenMP and CUDA to allow for efficient execution on multicore CPU and GPU architectures. GOMC employs widely-used simulation file types (PDB, PSF, CHARMM-style parameter files). GOMC can be used to study vapor–liquid equilibria, adsorption in porous materials, surfactant self-assembly, and condensed phase structure for complex molecules.
JETSCAPE
The Jet Energy-loss Tomography with a Statistically and Computationally Advanced Program Envelope (JETSCAPE) collaboration is an NSF funded multi-institutional effort that brings together experimental and theoretical physicists, statisticians, and computer scientists to design the next generation of event generators to simulate the physics of ultra-relativistic heavy-ion collisions. An open-source software framework is available to researchers to use existing simulation packages contributed by members of the collaboration as well as to develop and test their own models.
