My specialty is theoretical high energy physics. This is the area of physics that deals with the most fundamental constituents of matter. My interests center mainly on the properties of relativistic quantum field theory, the theoretical framework used to describe elementary particles and their interactions.
I also have an interest in high-performance scientific computing, including parallel computing and visualization.
TSIL is a software library, written with Steve Martin, for the numerical evaluation of dimensionally-regularized two loop self-energy integrals with arbitrary masses and external momentum.
Project NANO is a National Science Foundation sponsored effort to bring nanoscience and nanotechnology into the science curriculum at Otterbein. Project activities include a workshop for high school science teachers, new laboratory activites using scanning tunneling microscopes, and joint Chemistry/Physics advanced laboratory exercises.
The Center for Computational Science was created in June 2003 with the acquisition of a 16-processor "Beowulf" cluster, and serves as a resource for teaching and research in all disciplines with an interest in computational science. The system was acquired initially via a grant from the Ohio Supercomputer Center as part of their Cluster Ohio program, and was a distributed-shared-memory parallel computer. It had eight nodes, each containing a pair of 733 MHz Intel Itanium (IA64) processors and 4GB of main memory. The system is currently being reconstructed by students with 16 single-processor nodes, each with a 2.4 GHz P4 CPU and 2GB of memory. Total system memory is 32GB. Each node also contains a 17Gb SCSI hard drive for use as temporary storage. Inter-node communication (for message passing) is handled via Myrinet.
The software environment is Linux, with Intel C, C++ and Fortran compilers, the Etnus Totalview debugger, and various libraries and other tools. The MPI and OpenMP parallel programming standards are supported, and batch requests are handled by PBS with the Maui scheduler.
Peak performance will be more than 150 GFLOPs.
