Research Interests

My research has been dedicated to develop high quality computer models to solve large-scale complex problems using high performance scientific computation and information technology. Currently, as a Research Assistant Professor, my work (with Dr. Louis J. Gross, and Dr. Michael W. Berry) focuses on an NSF ITR project, Grid Computing for Ecological Modeling and Spatial Control. My main trusts include the development of Geographic Information System (GIS) enabled cyber-infrastructure (ArcGIS Server/Engine plus J2EE/Spring/Hibernate/Eclipse) for dynamic natural system simulation and fault-tolerant spatial control algorithms for PetaScale computers. In the past years, I was working on another NSF ITR project - Parallel and Grid Computing for Environmental Multimodling, which aims to explore the techniques and roadmap for next generation high-performance ecosystem modeling. Technically, I have developed a novel methodology to map a large-scale ecological multimodeling system (ATLSS) on a heterogeneous computing grid (SINRG), which, in turn, provides supercomputing power for many remote naive users (natural resource managers) at South Florida. Beside necessary multidiscipline knowledge requirements for the state-of-the-art large-scale practical ecological multimodeling, my approach also involves efforts on many frontiers of high-performance computing (with Dr. Jack Dongarra's Innovative Computing Laboratory), including parallel programming (using MPI, Pthread, OpenMP), metacompuing (using PVM) and grid and cooperative computing (using Globus, NetSolve, IBP, WebServices, J2EE). I taught a graduate level course Computational Science for Natural Resource Management and also a faculty member of ITR workshops. Beside the research at UTK, as a computational scientist, I also work with Dr. Joseph E. Flaherty, Dr. J. Russell Manson and Dr. Steve G. Wallis on Environmental Modeling on Distributed Computing Platforms, a continuous work from my Ph.D. dissertation.

Multi-disciplinary Background and Experience on High Performance Computational (HPC) Facilities

My strong multi-disciplinary background directly comes from research and education in many science and engineering fields, including Computer Science, Environmental Engineering, Civil Engineering, Chemical Engineering, Mathematics, Ecology, Planning and Management, Earth and Environmental Science, and Electrical, Computer, and Systems Engineering.  My extensive experience on high performance computing also directly comes from research on a variety of supercomputers, including SMP: SGI Origin 2000 (12@RPI), SUN E25K (128@TACC), SGI Altix (256@ORNL). CLUSTER: IBM SP2 (32(4)@RPI, 184(4)@UT), IA-64 Linux Cluster (32(2)@UI), SUN Fire Cluster (32(2)@UT), IBM Power4 (27(32)@ORNL), IBM BlueGene (1024(2)@SDSC), IBM p690(384(2)@SDSC), IBM p655(272(2)@SDSC), HP Alphaserver(750(4)@PSC), Cell Broadband Engine (20(9)@Terra), as well as a “do-it-self” Beowulf (7 nodes).
