Interests (Work Related):
I am currently working on experiments at Thomas
Jefferson National Accelerator Facility (Jefferson Lab) to measure strangeness
production in electron-nucleon reactions and to study the excited states of the nucleon. These
experiments use the CEBAF Large Acceptance
Spectrometer (CLAS). This first of its kind superconducting toroidal magnet allows for
the precise identification of multiple particle final states. Commissioning of this
detector began in November of 1996. The first
experiment began in December 1997 and was completed in March 1998. As part of the
international collaboration building this device, my efforts have focused on the software
and computer hardware needed to run the device and to collect and analyze the data from
experiments done using CLAS.
- I am also interested in science education and have devoted a significant
fraction of my effort toward improving the computer technology in the undergraduate
physics labs, developing and improving science demonstrations, and exploring the potential
of the world wide web as a teaching device.
- Recent Activities:
- Developing distributed software for the CLAS
experimental program, including software for data acquisition, detector simulation, event
analysis, and experiment database management.
- Building a distributed computing cluster from
commodity priced computers for CLAS data analysis and have just begun a project to build a
similar computer system for on-line event analysis at CLAS.
- Developing the specifications for a computer
system for data acquisition and analysis for a Meson Physics Facility
at Jefferson Lab
- Taking Part in Grand Challenge in High Energy and
Nuclear Physics Focussed on Efficient Data Access for Relativistic Heavy Ion Collider
- Past-Chairman for the Jefferson Lab User's Group
Board of Directors
- Chairman of the Jefferson Lab Physics Computing Advisory Committee.
- Rewrote the software for Physics 2048C (General Physics A) laboratories.
- Developed and am currently maintaining Web resources for Physics 2048 and Physics 2049.
- Developed Web-4M (now a commercial product) for
on-line collaboration and education
- Developed and currently maintaining a science and mathematics activities page, Cyberspace Middle School, on the
World Wide Web
